21-Day Tummy: Rids Bloat and Belly Fat

21-Day Tummy is a diet plan that targets excess weight and belly fat while also dealing with common digestive problems.


It is the creation of Liz Vaccariello, the editor of Reader’s Digest and bestselling author of The Flat Belly Diet. She states the following:

You will shrink your waistline, soothe your stomach and reduce your dependence on antacids and other medications.

Her sensitive stomach meal plan helps dieters address the root of the problem by reducing inflammation and balancing gut flora.

21 Day Tummy Diet Basics

21-Day Tummy is designed specifically for people with digestive issues.

You can lose up to 4 ½ inches off your belly as you learn about foods that protect your digestion.

21-Day Tummy can help you manage the 5 major digestive problems:

Diet for a Sensitive Stomach

Vaccariello details how chronic inflammation and the wrong diet can weaken immunity, imbalance gut flora, and damage digestive function. Even some seemingly “healthy” foods can cause gas and bloating, heartburn, indigestion, constipation, and IBS flare-ups.

This program helps you break the vicious cycle and alleviate your symptoms by eating foods that are right for your body.

You will learn how to identify potential problematic foods that may be aggravating your digestive issues. However, guidelines are offered on how you can eventually incorporate trigger foods back into your diet. This means you don’t have to give up your favorite foods forever.

Gut Friendly Recipes

The book includes over 50 recipes that follow these principles:

  • High in magnesium
  • Contain anti-inflammatory fats
  • Low in carbohydrates
  • Fewer FODMAP foods (a common cause of gas and bloating)
Each meal helps improve digestive function while simultaneously helping you achieve a flat belly.
