Tag: Severe caloric restriction

Studies have repeatedly shown that severe caloric restriction, often seen in crash dieting, can trigger a 'starvation mode' response in the body, which significantly slows down your metabolism. Understanding these dangerous problems associated with severe caloric restriction is crucial for anyone considering a rapid weight loss strategy that involves extreme energy deficits.

The body’s primary objective in a survival scenario is to conserve energy, drastically slowing metabolic processes to function on significantly fewer calories than normal. This mechanism determines what is the minimum kcal to survive, but this level of consumption is extremely dangerous and unsustainable.

According to research, very low-calorie diets (VLCDs) can lead to rapid weight loss in the short term, but they also carry significant risks, including an increased risk of gallstones, fatigue, and other health complications. This highlights the critical importance of understanding **what happens in a severe calorie deficit** and why it is not a safe or sustainable strategy for most people.
