The Flat Belly Diet is a program in a book which is co-written by the editor-in-chief of Prevention magazine, Elizabeth Vaccariello and a nutritionist named Cynthia Sass. It claims to be able to help its readers to flatten their bellies and lose up to fifteen pounds in the first month that they use the various diet plans that the book contains.

This makes the Flat Belly Diet appear extremely appealing.  After all, who isn’t interested in a weight loss strategy that brings results – particularly fast ones – targeting one of the most challenging areas for size reduction?

What’s Involved in the Flat Belly Diet?

This diet is not considered to be a restrictive one, having even fewer restrictions than the South Beach diet, which is known for being relatively lax. It suggests a diet plan with a combination of unrefined foods such as organic produce and whole wheat, but almost no meat, along with one “MUFA” (a food which contains a monounsaturated fat) per meal.

According to Vaccariello, the MUFA foods are central to minimizing belly fat and achieving a lean stomach without risk of bloating so that the result is slimmer and more muscular. Furthermore, the Flat Belly Diet includes what they call “sassy water”, which is a combination of citrus fruits, spices, and cucumber mixed in water. In this diet, exercise is only optional.

Flat Belly Diet Pros

The advantages of the Flat Belly Diet include the fact that:

  • It does put good nutrition at the forefront of the meal plans,
  • It focuses on unprocessed, natural foods that are high in vitamins, minerals, and other nutrients.
  • Some people feel that it is a benefit that exercising is not required in order to stick to the Flat Belly Diet rules.
  • There is no calorie counting required, making it less complicated to keep track of what can be eaten in a day. This being said, the daily caloric intake when following this meal plan is generally 1,600 calories.

Flat Belly Diet Cons

Conversely, the drawbacks of the Flat Belly Diet include the fact that:

  • The foundation of the diet claims that the consumption of monounsaturated fats can assist in reducing bloating in the belly area. This is not supported by large medical studies on human subjects.
  • Although it does allow for more flexibility and freedom in terms of caloric intake, the higher permitted calories every day are higher than what most calorie-counting diets allow and may therefore lead to slower weight loss or no weight loss at all.
  • Another struggle that some people experience with the Flat Belly Diet is that the food items it requires may be challenging to find in a grocery store.

Challengingly Easy

Though it may have been designed by names with hype behind them, there is little fact to support this diet. That being said, it is nutritionally sound and will be well balanced and healthy, if not effective for weight loss. Moreover, while there aren’t a large number of restrictions and the concepts behind this diet are quite straightforward, the Flat Belly Diet appears to be easier said than done.

Since the ingredients needed are hard to obtain, it means that people following the Flat Belly Diet will need to go out of their way to get them.  This suggests that while some dieters may keep it up for a time, it’s not something that will be maintained over the long term.  Any diet program that is not kept up beyond initial lost weight places the dieter at risk of regaining the pounds.

I am suffering from belly fat. Please help me;

Is “Flat Belly Diet” a right product for rid from belly fat?

This is a good diet if you’re focusing just on your belly. If you’re not worried about overall weight loss but you’re trying to slim down around the middle, this one’s pretty great.

I found that when I followed this to the letter and really kept up with exercises that focused on the tummy area, I got great results. Good luck for you, too!

I was also suffering a lot from belly fat, then my friend suggest me this diet, I did it and I am still looks good, This diet is really impressed me….!

I’m looking for something to help me with the mess around my middle, too. Is this a fast diet? How much did you lose and how quickly? I really want to choose something that will work. I’m done with getting myself into diet programs that won’t get me anywhere or that work for a short time and then I just bloat back up again and get fat all over. I’m trying to find something that real people have actually tried before me. I don’t trust the testimonials on the official sites.

I wouldn’t want to use this if I had to lose a lot of weight, but if you’re just trying to get that muffin top under control, this is pretty good. It just helps to slim things down and get rid of that extra jiggle. It isn’t all that hard and it feels pretty natural.

To be successful with any diet you have to make it part of your everyday lifestyle. I find that this diet does work for me. I have tried Weight Watchers and South Beach in the past, but with WW I was always hungry and if I fell off the wagon I would fall hard and have huge cravings. With S.B., I found it was pretty healthy but the second I ate any extra carbs the weight loss would stop. I also got a lot of headaches. With this diet, The four small meals and whole grains, nuts and seeds seem to be the best diet for my taste/hunger issues. It fills me up and carries me throughout the day. I also love avocado and dark chocolate.

That’s a very good point, Grace. No matter how good a diet may be if you follow it exactly, you still need to actually be able to follow it to make it successful!

My thoughts exactly, Grace. It’s not enough to make dramatic changes with the belief that you will be able to keep the fat off after you stop doing them anymore. Starving yourself or doing anything else that you don’t plan to maintain over the years is just asking for a yo-yo effect. The flat belly diet might help you to get your middle under control, but you’ll need a long term plan.

I did feel like I was eating all healthy foods on this diet, but I also felt like I was really starving myself. This really seemed like an ultra low cal diet to me. Maybe it’s just because I’m not used to counting calories.

This is a good diet because belly fat is the most dangerous kind
