After about two to seven days of following this eating routine, you go into something called ketosis, or the state your body enters when it doesn't have enough carbs for your cells to use for energy. Then it starts making ketones, or organic compounds that your bod then uses in place of those missing carbs—and oh, it also burns fat for more energy, says Beth Warren, R.D., founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.
Do not try to lose weight too rapidly. Crash diets and diet pills that promise weight loss are usually bad for you and actually don't help keep the weight off in the long run. Resist the urge to take the "easy" way out and instead stick with a healthier lifestyle. This way you lose the weight and improve your health, helping you keep the weight off in a way that won't harm you in the long run.
