Do aerobic exercises daily. Sure, you can do 100 crunches a day, but if you've got a layer of belly fat covering up your ab work then what's the point? You need to burn the top layer of stomach fat to see the changes. Cardio exercises will heat up your core temperature and improve circulation, both of which will aid in acquiring a flat stomach. Strive for at least 30 minutes a day minimum, but include 1-2 days of rest each week.
Muscle is more metabolically active than fat, which means the more you have, the faster your metabolism is and the more calories you burn all day long—all key for a whittled middle.

For fat-melting cardio, all you need to do is your weight, he adds: If you’re 145 pounds, do 145 minutes a week, broken up however fits into your schedule—say, 60 minutes Saturday, 45 Tuesday, and 40 Thursday.

Wondering what C.R.A.P. is? Well, it is a group of food that does no good to your body. C for caffeine, R for refined sugar, A for alcohol and P for processed food. If you remove these four food groups from your life, you can live your dream of a flat belly. One of the biggest enemies of a flat stomach, these groups cling to your bodies and make it difficult for you to lose fat.
With our new 21-Day Tummy plan, you will be eating more anti-inflammatory foods, especially those rich in magnesium, and fewer carb-dense foods and FODMAPs (rapidly fermentable carbohydrates that can aggravate your gut). This plan helped my fellow testers and me shrink our stomachs (by up to 4 1/2 inches in one case!) and ease our tummy troubles. At least two people stopped taking prescription drugs for heartburn entirely, and GI symptoms disappeared completely for several testers.
