12 Sneaky Food Additives That Are Destroying Your Metabolism

2. Monosodium Glutamate (MSG) – The Silent Appetite Booster

MSG is a flavor enhancer commonly found in fast food, canned soups, instant noodles, and frozen meals. While it makes food taste more addictive, it also disrupts the hypothalamus, the part of your brain that regulates metabolism and hunger. Research suggests that MSG consumption can increase appetite, promote fat storage, and contribute to metabolic syndrome. It may also cause inflammation, which is linked to slower metabolic rates and weight gain. Avoid it in: Chips, processed meats, flavored seasonings, and frozen dinners.
