21-Day Tummy Diet Review

The 21-Day Tummy Diet was written by Liz Vaccariello, who also wrote the Flat Belly Diet. In this book, Vaccariello addresses the proper foods to eat, as well as the ones to avoid, so dieters can successfully tackle heartburn, bloating, constipation, diarrhea, and irritable bowel syndrome.

The 21-Day Tummy Diet contains over 50 recipes of foods that are said to be “gut friendly.” These foods are typically ones that are high in magnesium, contain anti-inflammatory fats, and are low in carbohydrates. When followed properly, the 21-Day Tummy Diet is said to have dieters feeling better and see their tummy trim up all within the 21 days of the diet.*

Do Dieters Lose Weight On The 21-Day Tummy Diet?

The 21-Day Tummy Diet restricts many foods and food groups; because of this fact, it is very likely that a dieter will see a large reduction in their daily caloric intake.* So, some weight loss can be expected, especially in the short term.

However, long-term weight loss will depend on the dieter. Should the dieter partake in the optional exercise regimen, their results will likely be greater than those who do not. They will also need to remain true to the diet, even after the 21 days has come and gone.

Is The 21-Day Tummy Diet Easy To Follow?

The 21-Day Tummy Diet is a restrictive diet by nature; therefore, it will not be the easiest diet on the market to follow. Many mainstays in dieter’s lives, such as coffee and wine, are cut out completely. While a dieter can learn to live without such comforts, the initial process of weaning off of them can prove to be tough for many.*

In addition, the only exercise guidance that is given is in the way of breathing and yoga. While breathing exercises are not hard to learn, yoga is not for everyone,and those who have pre-existing injuries might find that doing the stretching and routines all but impossible.


The 21-Day Tummy Diet book retails for $26.99, but unfortunately the diet is not all it’s cracked up to be. The book claims that by eating a certain way and by doing limited exercises, you can target your tummy and flatten it in just 21 days.*

However, there is no such thing as targeted weight loss. Proper weight loss that will last can only come as the result of proper nutrition and full body exercise. For that, you will have to seek out a diet plan that is a bit more comprehensive than the 21-Day Tummy Diet.
