Try not to Count Calories 

In case you're a competitor, model, or wellness coach, definitely, tally the calories you expend. Be that as it may, in case you're 200-something pounds, tallying calories isn't the correct method to begin your weight reduction experience. 

Why? This is a direct result of the hormonal lopsided characteristics you no doubt have. These hormonal harms incorporate the accompanying: 

A. Insulin obstruction 

Carbs are fine, yet perhaps not for you. Expending sustenances with high carbs substance wouldn't give you the vitality you need; they will simply be put away in your body on account of its protection from insulin. 

Insulin is the hormone in charge of moving glucose from the nourishment into the cell so you can utilize it as vitality. 

Insulin opposition causes weight gain. Cut down on your carbs consumption and present them later when your hormones are adjusted. 

B. Leptin opposition 

Leptin is the hormone in charge of sending a sign to the cerebrum that you're as of now full or have a few calories to consume. Since you're impervious to insulin, leptin is additionally getting blocked. 

This is likewise the reason you first need to concentrate on sustenance; exercise will fall into place easily once it's fixed. 

To adjust your leptin, expend veggies and lean protein, and take less carbs. 

Fix Your Gut 

Another conceivable issue on the off chance that you weight 200 lbs or past is gut irritation. Because of this, your body can't process and retain the nourishments you eat. Also, indeed, even the solid ones!

Warm water – 1 glass 
ACV – 1-2 tbsp. 
Lemon juice – 2 tbsp. 
Cinnamon – ¼ tsp – (must be Ceylon cinnamon, typical Cinnamon isn't alright for consistently Consumption. ) 
Cayenne pepper – 1 dash 
Ground ginger – ½ tsp (Too quite a bit of this makes it difficult to drink so 1/4 tsp is ideal) 
Crude nectar – 1 tsp. (Must be crude, or neighborhood nectar – discretionary to include some sweetness, suggest skipping for the time being)

Walk, Walk, Walk 

Since you ought not connect with yourself in an extreme exercise, a great option is to complete a ton of strolling. 

Strolling, however it sounds and is straightforward, is powerful in helping you on your weight reduction venture. 

More or less, strolling improves your stance and blood stream and consumes increasingly fat. In the event that you can't completely walk, don't constrain yourself. Do what you can now. 

Think about Your Emotions 

Many individuals experience the ill effects of enthusiastic and gorging, which are normally brought about by a flood of feelings or condition, including: 

↪Companion weight 

Tending to your feelings is critical in dispensing with enthusiastic and voraciously consuming food. 

The passionate part of weight reduction is as significant as the physical, so considering it within the sight of a care group can fundamentally help. 

Acknowledge and Love Yourself 

Self esteem and acknowledgment is a ground-breaking weapon to keep attempting to achieve your objective of improving as a form of yourself.

Rare Recessive Mutations Pry Open New Windows on Autism

Sunday, June 23, 2019 0
Comprehensive study offers previously unknown clues to autism's underlying biology

Over the past decade, autism spectrum disorder has been linked to mutations in a variety of genes, explaining up to 30 percent of all cases to date. Most of these variants are de novo mutations, which are not inherited, affect just one copy of a gene, and are relatively easy to find. The lab of Timothy Yu, MD, PhD, at Boston Children's Hospital chose a road less travelled, tracking rare recessive mutations in which a child inherits two "bad" copies of a gene.

The study, involving one of the largest cohorts to date, suggests that recessive mutations are more common in autism than previously thought. The findings, published June 17 in Nature Genetics, provide a likely explanation for up to 5 percent of all autism cases and offer new clues to autism's biological causes.

"This is the deepest dive yet into recessive mutations in autism -- but we're not done," says Yu, who led the study with first author Ryan Doan, PhD, in Boston Children's Division of Genetics and Genomics. "This study offers a glimpse of an interesting part of the puzzle we've yet to assemble."

Doubling down on double hits

Recessive mutations have been linked to autism in the past, mostly in small study populations in areas where marriages between relatives are common. When parents are fairly closely related genetically, their offspring are more likely to get "double hits" of genetic variants -- mostly harmless, but some of which may be disease-causing.

The new study represented a much broader population: 8,195 individuals in the international Autism Sequencing Consortium, founded by study co-author Joseph Buxbaum, PhD, of the Icahn School of Medicine at Mount Sinai. The study included 2,343 individuals affected with autism from the U.S., the U.K., Central America, Germany, Sweden, the Middle East, and Finland. It examined whole-exome data, comparing DNA sequences for all protein-coding genes in these individuals with autism, versus 5,852 unaffected controls.

The researchers first looked for "loss of function" or "knockout" mutations that completely disabled the gene, such that the proteins they normally encode are truncated and non-functional. "The concept is simple, though the execution took a lot of careful work," says Doan, who was the study's first author.

The team identified loss-of-function mutations that were both rare (affecting less than 1 percent of the cohort) and biallelic (affecting both copies of the gene) in 266 people with autism. Overall, people with autism were 62 percent more likely than the control group to have disabling mutations in both copies of a gene.

The team also looked for biallelic missense mutations, which involve a change in a single amino acid (a "spelling error"). Missense mutations are more common than loss-of-function mutations, and some of them cause just as much damage. Biallelic missense mutations, too, were significantly more common in the autism group.

Biological clues

After excluding genetic variants that were also found in the control group and in a separate large cohort of more than 60,000 individuals without autism, Doan, Yu and colleagues were left with 41 genes that were knocked out only in individuals with autism. Overall, the researchers estimate that these genes explain another 3 to 5 percent of all cases of autism (2 percent from loss-of-function mutations, and 1 to 3 percent from missense mutations).

Eight of these had already been flagged in previous studies. The remaining 33 had never been linked to autism before, and several have intriguing attributes that call out for more investigation.

One gene, SLC1A1, for example, helps modulate activity of the brain neurotransmitter glutamate, and has been linked to a metabolic disorder associated with intellectual disability and obsessive-compulsive disorder. Another gene lost in two brothers, FEV, is critical for making the brain neurotransmitter serotonin, providing further support for the idea that dysfunction of serotonin signaling is central to autism.

Many of the double knockouts were found in just one individual and would need to be confirmed in other patients, Yu notes.

Male susceptibility to autism confirmed

Rates of autism are known to be higher among males than females, in a roughly 4:1 ratio. Yet previous studies, mostly looking at de novo mutations have found that boys tend to have milder mutations and girls tend to have more severe mutations, a seeming contradiction.

"One hypothesis is that the female brain is somehow more robust -- that it has more reserve and are more resistant to autism, so it takes a bigger hit to knock them down," says Yu. "We asked, does the same pattern hold true for recessive mutations? And we found that it does -- females had a higher rate of complete gene knockout than males."

In fact, a surprising 1 in 10 girls had a biallelic gene knockout caused by either loss-of-function mutations or severe missense mutations. And interestingly, one boy with autism lost a gene involved in estrogen signaling, suggesting that something in the estrogen pathway could be a risk factor for autism.

Supporters of the study include the National Institutes of Health, the Nancy Lurie Marks Clinical and Research Fellowship Program in Autism, the National Institute of Mental Health (NCRR 1S10RR028832-01, RC2MH089952, RO1MH083565, R01MH113761), the Simons Foundation Autism Research Initiative (SFARI), the National Institute of Child Health and Human Development (U19HD077671, U24HD0938487), and the Howard Hughes Medical Institute.

Lose Weight for Wedding in 2 Weeks

Saturday, June 22, 2019 0
How I did it and my secrets

1. Track your nourishment. 
That implies every last bit of it, from the spoonful of soup you tested for your gathering menu to the little chomps of cake you taste. These "concealed" calories are anything but difficult to bypass however can truly include. Furthermore, inquire about demonstrates that the basic demonstration of following your nourishment can enable you to lose twice as much weight than if you don't follow by any stretch of the imagination (mental following does not check). On the off chance that you don't do anything else during the last days and weeks before your wedding, track your nourishment industriously consistently. 

2. Test brilliant. 
A continuation of tip #1, on the off chance that you realize you will test an assortment of sustenances in a brief timeframe, keep the parts little. Only a couple of nibbles of cake or your food provider's mark fish dish ought to be adequate for taste testing. What's more, on the off chance that you realize you're going to test an assortment of desserts one day, cut back on sugary sustenances for the following couple of days to refocus. Choose which nourishments you'll have (and how much) and utilize SparkPeople's free Nutrition Tracker to remain inside your calorie extend. 

3. Have breakfast. 
Breakfast is the most effortless feast to plan and it sets the phase for your day. Have an empowering breakfast to get your digestion started up, and after that you'll be bound to settle on sound decisions for the duration of the day—like requesting a shrewd lunch and swinging by the exercise center after work. Stunningly better: Eating breakfast can enable you to get more fit, as studies have indicated breakfast eaters will in general devour less all out calories during the day than individuals who don't eat a morning feast. 

4. Make wellness a need. 
I like to remind individuals that nourishment is just a single piece of the condition that decides if you'll lose or put on weight. Wellness is similarly as significant. Try not to release your exercises by the wayside. On the off chance that anything, you ought to give work a shot more than previously in the event that you truly need to drop a couple of pounds, particularly around the days that you're testing the majority of that rich and delightful sustenance. With a tumultuous timetable, by what means will you fit it in? That is the thing that this next tip is for. 

5. Treat your exercises like an arrangement. 
You wouldn't miss your cake tasting, pre-marriage mentoring session or dress fitting, OK? Add your exercises to your schedule with the goal that different commitments don't hinder your rec center time. When meeting to talk about plans with your life partner, guardians, marriage gathering or wedding organizer, head out for a walk (or walk about the room in case you're on the telephone) for a bit of performing multiple tasks. Furthermore, when your marriage gathering needs to plan your single woman party, reveal to them you'll be there, however not until after Pilates class lets out. 

6. Get support. 
It very well may be hard to remain solid and responsible to your objectives in the event that you don't have any other person applauding you. It very well may be significantly progressively hard to do as such when individuals are attempting to attack your endeavors, maybe unwittingly. The most ideal approach to get backing is to tell somebody—anybody—about your weight and wellness objectives and request their help. In the event that you feel too awkward to even consider sharing those subtleties with somebody you know, the SparkPeople people group is incredible for that. You can interface with individuals who have comparable objectives and get tips, inspiration and your very own cheerleading squad. Make certain to look at our ladies to-be SparkTeams too on the grounds that these ladies know precisely what you're experiencing. 

7. Farthest point liquor. 
It brings down restraints, making it almost certain that you'll disregard your sustenance plan and enjoy. In addition, liquor alone is quite high in calories. On the off chance that you can unwind and de-worry without drinking by any means, you'll be in an ideal situation. On the off chance that you should drink, nurture your glass gradually, pick diet-accommodating beverages, and breaking point the quantity of servings. Gracious and truly, liquor contains calories, so add each beverage to your Nutrition Tracker. 

8. Pick sound settings for pre-wedding merriments. 
There will be showers, gatherings, and trips in abundance as your wedding draws nearer. In the event that you have any state in how these occur, pick an invigorating café where you realize you can get a decent, nutritious feast without going over the edge. Need assistance? Allude to our Dining Out Guide for the most beneficial decisions at pretty much any chain café. Concentrate on your loved ones while you're there, getting a charge out of the great discussion and exercises as opposed to drifting around the hors d'oeuvres. Make enduring recollections that don't rotate around eating, and you won't feel like you're passing up a major opportunity. 

9. Catch your zzz's. 
Your brain and schedule might be brimming with to-dos, however is "a lot of rest" on your motivation every day? It ought to be. Too little shuteye can obstruct your weight reduction endeavors, expanding desires and prompting poor decisions. Remaining composed will help, yet do you best to adhere to a steady rest plan, going for at any rate 7-8 hour hours out of every night—including ends of the week. 

10. Try not to make mountains out of molehills. 
It's anything but difficult to go over your calories one day and feel like a disappointment. In any case, recollect that it takes significantly more than one day of gorging to defeat your advancement. Acknowledge your slip-ups, gain from them and proceed onward. Here are 25 different ways to refocus today. 

11. Avoid crazes. 
When somebody is urgent to get more fit rapidly, she'll for the most part go to some faulty measures. Be vigilant for craze counts calories and don't succumb to wellness tricks either. How would you spot them? By their unrealistic cases. Prevailing fashion diets don't work and their outcomes are passing. Instead of hazard a methodology like that, stay with basic, sound propensities that you know have any kind of effect, similar to the things on this rundown. 

12. Keep up a functioning way of life. 
Keep in mind that "running" errands as you plan your wedding isn't equivalent to really running—or practicing so far as that is concerned. Try not to mistake hecticness for wellness. The more physical action you can add to your days (notwithstanding arranged wellness) the happier you'll be. Attempt short exercises and discover basic approaches to transform vacation into dynamic time. 

13. Keep a crisis nibble available. 
Reserving some sound and versatile nourishments in your vehicle, handbag, and work area cabinet can help fulfill your desires and keep you from going over the edge on all the wrong sustenances. This is a smart thought when you're eager at work and treats sound enticing, or when you're out throughout the day and see the sparkling cheap food signs alluring you. 

14. Try not to give yourself a chance to get to hungry. 
Between brilliant nibbling and adjusted dinners, keeping your body appropriately energized can enable you to keep hunger under control. Eating pretty much nothing, then again, makes gigantic longings that are too difficult to even think about ignoring. When you let yourself become insatiable, you'll snatch anything, and as a rule a great deal of it, to suppress your distress. Keep hunger under control with legitimate arranging. Carry snacks with you. Keep solid alternatives close by. Furthermore, never go over 4 hours without eating. 

15. Oversee pressure. 
What future lady isn't stressed over the subtleties, the arranging, and even spasm of her dress? Life doesn't stop since you're arranging a wedding, and all that pressure can complete a number on your psychological well-being—and your waistline. Its a well known fact that perpetual pressure can add to weight issues, particularly in case you're inclined to enthusiastic eating. Ensure a little R&R makes it into your day, regardless of whether it's as basic as a 1-minute breathing activity or an additional couple of minutes in a hot shower. Obviously, practice is an incredible method to calm pressure and help you achieve your objective weight. 

16. Drink your water. 
Late investigations found that when individuals drink more water for the duration of the day, they end up eating less all out calories. Another new investigation found that drinking water before every feast brought about more prominent weight reduction. Water and water-rich sustenances can help top you off longer. Keep some water close by at gatherings, taste water among nibbles, and meet your day by day quantity to help avert gorging. 

17. Wake up with exercise. 
Individuals who exercise before anything else are bound to practice routinely than the individuals who exercise later in the day. Regardless of whether you're not a morning exerciser yet, a.m. exercises may be the most ideal approach to press wellness into your prior days different things come up. Additionally, when you practice first, you're less inclined to enjoy with nourishment later.

Treatment for Common Cause of Diarrhea More Promising

Friday, June 21, 2019 0
Intestinal parasite Cryptosporidium successfully grown in lab using new technique

One of the most common causes of diarrhea worldwide -- accounting for millions of cases and tens of thousands of deaths, mostly of small children -- is the parasite Cryptosporidium. Doctors can treat children with Cryptosporidium for dehydration, but unlike many other causes of diarrhea, there are no drugs to kill the parasite or vaccines to prevent infection.

Now, researchers at Washington University School of Medicine in St. Louis have figured out how to grow the most common type of Cryptosporidium in the lab, a technological advance that will accelerate e

"This parasite was described over 100 years ago, and scientists have never been able to reliably grow it in the lab, which has hampered our ability to understand the parasite and develop treatments for it," said senior author L. David Sibley, PhD, the Alan A. and Edith L. Wolff Distinguished Professor of Molecular Microbiology. "We now have a way to cultivate it, propagate it, modify its genes and start figuring out how it causes disease in children. This is a first step toward screening potential drugs and finding new drugs or vaccine targets."

The findings are published online June 20 in Cell Host & Microbe.

In wealthy countries, Cryptosporidium is notorious for causing water-borne outbreaks of diarrhea. The parasite goes through a complex life cycle, including a stage in which it is called an oocyst and becomes hardy, spore-like and hard to kill with chlorine, bleach or other routine sanitation measures. In 1993, 400,000 people in the Milwaukee area developed diarrhea, stomach cramps and fever after a malfunctioning water purification plant allowed Cryptosporidium into the city's water supply. Every year, dozens of smaller outbreaks are reported in the U.S., many associated with swimming pools and water playgrounds.

Diarrhea caused by the parasite can last for weeks. While this is miserable for otherwise healthy people, it can be life-threatening for undernourished children and people with compromised immune systems.

Until now, researchers who wanted to study the parasite had to obtain oocysts from infected calves -- Cryptosporidium infection is a serious problem in commercial cattle farming -- and grow the parasites in human or mouse cell lines. The parasite inevitably would die after a few days without going through a complete life cycle, so the researchers would have to obtain more oocysts from cattle to do more experiments.

Sibley, along with co-first authors Georgia Wilke, PhD, who is a student in the Medical Scientist Training Program, and postdoctoral researcher Lisa Funkhouser-Jones, PhD, suspected that the problem lay in the cell lines traditionally used to grow the parasite. Derived from cancer cells, these cell lines were very different from the normal, healthy intestine that is the parasites' usual home.

To create a more natural environment, the researchers collaborated with Thaddeus S. Stappenbeck, MD, PhD, the Conan Professor of Laboratory and Genomic Medicine and a co-author on the paper. Stappenbeck and colleagues cultured intestinal stem cells to become "mini-guts" in a dish -- complete with all the cell types and structural complexity of a real intestine.

When the researchers added oocysts to the mini-guts, the parasites thrived. They emerged from the oocysts and went through their full life cycle to produce more oocysts. For the first time, every stage of the parasite's complicated life cycle could be studied in the lab. The researchers also showed that they could edit the parasite's genes with CRISPR/Cas9 and perform genetic crosses, making these powerful tools for studying biology more accessible than before.

"We put the parasite in this environment that is much more natural, and it's happy and it grows and develops and goes through the entire life cycle," Sibley said. "This opens up possibilities that were closed for a long time. There is only one FDA-approved drug, and it doesn't work in young children. There are potential drug candidates, but we couldn't screen them before because the parasites would just die anyway. How can you tell if the drug is killing the parasites if they are already dying? Now we can start screening drugs and also start asking questions about what makes this parasite dangerous."

The technique applies only to C. parvum, one of the two most common Cryptosporidium species that cause diarrhea in people. Its cousin C. hominis is even more difficult to grow in the lab. The two are closely related, but while C. parvum can infect young mammals of many species, C. hominis only infects people.

"There are only a few dozen genes that are different between parvum and hominis but somehow that's enough to make hominis very finicky," Sibley said. "It won't grow in mice or in calves or, so far, in mini-guts grown from mouse stem cells. Developing systems to work with hominis is an important goal of my lab."

The technique, while potentially powerful, will not immediately translate into better treatment or prevention for diarrhea, Sibley cautioned.

"These things take time," Sibley said. "There's a lot of basic research that still needs to be done. But this system provides an important path forward. We can now use genetic approaches to study the role of individual genes and thereby identify important targets for improved therapies."

Afraid of food? The Answer May Be In The Basal Forebrain

Wednesday, June 19, 2019 0
After fasting for 24 hours the typical laboratory mouse spends much time eating. Surprisingly, this is not what Jay M. Patel saw when he was studying basal forebrain circuits in mice.

"When I joined Dr. Benjamin Arenkiel's lab, they had just discovered a unique set of circuits in the basal forebrain, a region separate from the hypothalamus, the brain area that normally regulates how much you eat depending on how much energy you spend," said Patel, a student in the neuroscience Medical Scientist Training Program (M.D./Ph.D.) at Baylor College of Medicine. "I wanted to investigate what these circuits that are linked to the feeding center of the brain were actually doing."

Using cutting-edge technologies, including microendoscopy-imaging protocols, Patel and his colleagues first investigated what types of stimuli would activate the circuits. By recording the activity of the neurons, Patel found that food odors highly activated a subset of neurons in the basal forebrain identified by the expression of the molecule vGlut2.

"That was very interesting because we know that the sense of smell can drive appetite. For instance, after smelling dessert, you may want to eat it even though you just had a big meal. Or conversely, after smelling a spoiled dish you won't eat it, even if you are very hungry," Patel said.

Although researchers knew that the perception of food odors itself can affect neuronal activity in the hypothalamus, it was unclear how odor perception was relayed to the hypothalamus. They were excited at the possibility that the novel vGlut2+ basal forebrain circuits might provide an answer.

Surprising results Patel and his colleagues studied the effect of specifically activating vGlut2+ neurons in the basal forebrain and observed dramatically altered feeding behavior in mice.

"Surprisingly, four to five days after we began the experiment, the mice started to lose weight quickly," Patel said.

The researchers determined that the animals' rapid weight loss could not be explained by metabolic dysfunction, as they found no differences between the levels of pituitary or thyroid hormones, or in the levels of glucose, insulin or leptin between the experimental and control groups. The mice lost weight rapidly because they had stopped eating.

"They did not eat even when they were hungry, which we found remarkable because animals are compelled to eat to survive," Patel said. Interestingly, further experiments showed that naturally aversive odors had a stronger effect on vGlut2+ basal forebrain neurons than food alone, triggering a food avoidance behavior in mice.

"It seemed that the animals were afraid of food," Patel said. "Even though they were hungry, they avoided locations where food was placed."

"We have identified a brain circuit driven by vGlut2+ neurons in the basal forebrain that suppresses appetite when it's active and stimulates feeding behavior when it's inactive," Patel said. "We also determined that this circuit, which is formed by just a couple of thousand neurons involved in perceiving the outside world, connects with and overrides feeding behaviors regulated by the hypothalamus."

"We think this work has potential implications that reach beyond feeding behaviors and mouse physiology," said Arenkiel, associate professor of neuroscience and molecular and human genetics and a McNair Scholar at Baylor. He is also a member of the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital. "This circuit is highly involved with how our brain perceives the outside world and brings this information to the hypothalamus, thus connecting with aspects of physiology like feeding, which relates to eating disorders that are associated with many neuropsychiatric conditions."

5 Fad Diets to Avoid

Tuesday, June 18, 2019 0
There are so many fad diets out there these days that attract people with there fast weight loss and celebrity lifestyle image. The fact is that nearly all of these diets only really offer short-term weight loss solutions and can be extremely unhealthy. Iv'e put together a list of 5 popular fad diets - along with reasons NOT to try them!

1.Detox Diet
Claims to lose a stone in 10 days, defeat cellulite, give glowing skin and no more bloating. This diet is meant to compliment other detox methods such as massages, colonic irrigation, saunas, fasting etc. Food such as fish, meat, eggs, dairy, wheat, salt, sugar etc are banned, while fruit, veg, beans, seeds, nuts are allowed. This results in a lack of nutrients, lowered immune system, a temporary weight loss, mainly water. It can lead to yo-yo dieting, nausea, sickness and headaches. It is said to causes food cravings, resulting in eventually giving up! It can also cause eating disorders and there is no good evidence of it actually working!

2.Low Carb / Atkins Die
The aim of low carb diets is to force the body to use its own fat as its main energy source. This produces something called ketone bodies to fuel body parts that can not use fat as an energy source such as the brain and red blood cells. This puts you in a state of ketosis - resulting in smelly breath and side effects like fatigue and nausea. These diets do produce short term results, which actually come from loss of muscle tissue and water. They are not a long term weight loss solution and are unhealthy if sustained.

3.Starvation Diet
Starving yourself is one of the worst diets that you could try. Ok, you may initially lose a lot of weight but the effect this has on your body is drastic! You will be extremely lacking much needed nutrition and this will lead to fatigue, lack of sex drive and hormones, sleep loss, possible hypothermia, poor concentration and judgement, depression, anxiety, personality changes, social withdrawal, your metabolism will dramatically slow down, you will lose organ tissue and muscles, you can get shakes, feel the cold more, and feel very week. Low calorie intakes actually slow down weight loss.

4.Hollywood Diet
This is basically a 24 or 48 hour 'Juice Fast' where you eat no food in this time. This diet has the same cons as the starvation diet. You are really just losing excess water in the body with this diet and it does'nt last long, you will soon put that weight back on. It is expensive to buy the juice, around $25! You will get no protein or iron in the body, and will be taking lots of sugar and carbs. Tastes good at first but soon turns very sickly.

5.Cabbage Soup Diet
This is a 7 day diet plan which supposedly offers a fast weight loss solution. This is a very short term solution and is not sustainable so is'nt a viable option for long term weight loss. There are a few benefits to this diet which include fast weight loss, a healthy beneficial change from eating junk food, and research has shown that cabbage helps to prevent cancer. However, the drawbacks do outweigh these benefits somewhat significantly. The soup is high in salt, lacking in good overall nutrition - low in protein, calcium, essential fatty acids, high in sodium and MSG, requires much will power as the soup tastes very bland and is extremely repetitive, gives you gas!, and most of all this is not a healthy sustainable solution to long-term weight loss. This diet will most probably make you GAIN weight as it has a very low calorie intake and you can get bloated!

There really is no substitute for a healthy diet and regular exercise if you want to lose weight and live an overall healthier and more active lifestyle.
