The Principles of the Belly Fat Diet
5 of 5
Limit your salt intake.
Salt doesn’t cause your body to gain fat, but it can still expand your belly. The major problem with sodium isn’t its calorie content but the fact that it causes water retention.
Your body contains many electrolytes, with one of the major ones being sodium. Electrolytes help control your body’s functions by carrying electrical impulses. The concentration of electrolytes must remain constant if your body is to function correctly.
So when your body has a high concentration of sodium due to an increased intake from the foods you eat, the kidneys retain more water in your bloodstream to help regulate your electrolyte levels. Water in the bloodstream moves into your skin through osmosis, giving you that puffy look and feeling.
If you’ve ever eaten a salty meal and had trouble removing your rings the next day, you’ve experienced this movement of water into your skin. Excessive fluid retention can also cause your stomach to look and feel bloated, making it difficult to have a flat belly.
