Low-calorie frozen meals
“Some of my clients think it’s a good idea to eat frozen meals with just 150 to 200 calories, but instead of helping you lose weight, this type of meal when eaten regularly may actually slow metabolism because you need to eat enough calories throughout the day to help keep your metabolism revving,” says Gorin. Frozen foods also tend to be loaded in sodium and lacking in fiber. If you’re going to eat a frozen meal, Gorin suggests pairing it with some pulses (beans, lentils, chickpeas, or dried peas). “They offer satiating fiber and protein—and eating just ¾ cup of them daily could amp up your weight loss (in one study, close to a pound in a six-week period). Also add some veggies to your meal—they’re full of water, which is hydrating and filling!” See here for more way to get a metabolism of a 25-year-old.
