Diets lower in carbohydrates or total calories may be helpful in losing body fat, but they come at a metabolic cost.
Over time, the body can become wise to the fact that you’re restricting energy and decrease production of thyroid hormone, which causes you to burn fewer calories. It’s part of your body’s survival instinct—it doesn’t want you to waste away. The problem becomes a double whammy when you eventually return to normal eating, as your metabolism will still be suppressed, making rebound weight gain an even greater concern.
Lower your carbs and calories gradually over time, making time for cheat meals once a week and re-feed days where you eat above maintenance levels.
