Your food cravings increase
Having the occasional craving for a snack between meals is normal. But if cravings are constant, and your meals aren’t satisfying your hunger, you might not be eating enough protein. Lisa DeFazio, RD, says that’s because protein helps regulate blood sugar. “Protein will slow down the absorption of your carbs—and slow down your blood sugars,” says DeFazio.
When you eat enough protein you’ll also feel fuller longer and won’t have mood swings, says DeFazio. A recent study published in Nutrition Journal also found that participants who ate a high protein breakfast had fewer “sweet and savory” food cravings. Some food cravings mean you’re deficient in other vitamins and nutrients like magnesium or potassium.
