Researchers found that the rate of weight loss does not affect the rate of weight regain. Moreover, rapid weight loss was more likely to lead to target weight loss with greater motivation to persist with diet and achieve better results.
Whatever the chosen type of diet, maintaining weight loss in the long term is the real challenge.
Are crash diets safe?
Most of us can go short periods without all essential nutrients, but not for long. Nutrient deficiencies can cause both short- and long-term health issues, and some can be serious.
Up to 25 percent of individuals who use very-low-calorie diets may develop gallstones. Also, when losing much weight quickly, some of it is bound to be lean body mass rather than fat.
Crash diets with little nutrition can weaken your immune system and increase the risk of heart muscle loss, palpitations, and cardiac stress. Consider the risks and talk to your doctor if you have any health conditions.
