If I eat at night will I gain weight?
There’s nothing wrong with eating a light, healthy snack after dinner as long as you plan for it as part of your daily calories. To keep from overeating, pay attention to your food while eating, avoid eating in front of the TV, and choose a portion-controlled snack. Some good options are packaged 100 calorie snacks, small servings of popcorn, ice cream bars, low-fat yogurt or fruit.
When you’re trying to lose weight, eat regular meals and consume 90% of your calories before 8 p.m. The benefit of eating meals every three to four hours is it helps regulate your blood sugar, and thus control hunger and cravings.
The bottom line: More research is needed on humans to determine whether calories eaten at night are more likely to cause weight gain than those eaten early in the day.
