how does eating one meal a day hurt you
If you eat one meal a day, you're more likely to binge and eat a whopper of a portion size to make up for the lost meals during the day, which will develop more fat into your body. Contrarily, if you don't eat enough, and assume eating one meal a day will make you slimmer, it will actually do your body worse.
Nutritionist Tracie Hyam also advises against a one-meal-a-day diet. Although it can lead to initial weight loss, she says it cannot be sustained and you'll eventually need to eat more. When you resume eating normally, you may well regain weight and experience physical discomfort, even internal damage.
