It’s Important to Eat
If the rule of weight loss is to burn more calories than you take in, not eating should make you lose weight fast, right? Wrong.
Animal studies show that with less eating, the body goes into “starvation mode,” burning fewer calories to conserve energy. Also, you’ll be short on nutrients, making you tired and sluggish.
To get your pep back, you might be tempted to eat sugary or fatty foods, which will pack all those skipped calories back on.
