3. Myth: Yo-Yo Dieting Will Ruin Your Metabolism Forever.
Reality: As bad as yo-yo dieting is, luckily, it’s not going to permanently ruin your metabolism. That’s not to say that yo-yo dieting is healthy — it’s certainly not — but that, with hard work, you can repair your metabolism to its normal rate.
4. Myth: Eat an Extra 3,500 Calories, and You’ll Gain 1 Pound of Fat.
Reality: Doctors have long touted the idea that 3,500 calories equals one pound of body fat. So, in order to lose one pound of fat a week, you need to eat 500 fewer calories a day. Keep doing that for a year, and you’ll drop over 50 pounds. Sounds great, doesn’t it? If only it were that simple. For one, the human body is hardwired to protect itself against famine, so it’s going to do everything in its nature to prevent weight loss. Your weight also fluctuates considerably based on the time of the day, how much water you’ve had, where you are in your menstrual cycle, hormones, etc.
