How I Get Slim and Look Good

A crash diet refers to willful nutritional restriction (except water) for more than 12 waking hours. The desired result is to have the body burn fat for energy with the goal of losing a significant amount of weight in a short time. There is a possibility of muscle loss, depending on the approach used.^{[clarification needed]} Crash dieting can be dangerous to health and this method of weight loss is not recommended by medical doctors.

Crash dieting is not the same as intermittent fasting, in which the individual periodically abstains from food (e.g., every other day).

According to the Academy of Nutrition and Dietetics, “If the diet or product sounds too good to be true, it probably is. There are no foods or pills that magically burn fat. No super foods will alter your genetic code. No products will miraculously melt fat while you watch TV or sleep. Some ingredients in supplements and herbal products can be dangerous and even deadly for some people” (2011). To feel healthier and live longer, the focus needs to be on making lifestyle changes to how a person eats.
