21-Day Flat Belly Meal Plan

Flat bellies are fab. But they’re not just for celebrities with access to trainers and nannies. You can slim your middle, too, and our 21-day flat belly meal plan is a delicious place to start.

This flat belly meal plan incorporates foods that will help trim the waistline. Some foods, like salmon and chicken, offer protein to build muscle tissue, which burns more calories than fat tissue. Healthy fats, like those found in avocados, are an important part of this meal plan too because they boost belly fat burn.
