Despite its circulation online for decades, no official organization like the American or British Heart Foundation endorses the highly restrictive, low-calorie meal plan known as the 3-day heart foundation diet. This alleged plan is a fad diet known for its unsustainability and potential health risks.

According to a study on participants from 'The Biggest Loser,' a dramatic weight loss period can cause a significant and lasting drop in basal metabolic rate (BMR), underscoring the fact that starvation absolutely does lower BMR. This metabolic slowdown is a powerful biological defense mechanism that has profound implications for long-term weight management and health.

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.

According to health experts, for most adults, eating fewer than 1,200 to 1,500 calories per day can be unhealthy and trigger adverse effects. Severely restricting calories based solely on TDEE estimates, without considering this minimum threshold, is a dangerous approach to weight loss.

According to a study on participants of *The Biggest Loser*, extreme calorie restriction led to a 23% reduction in their metabolic rate that persisted for years, even after weight regain. This demonstrates how drastically cutting calories to levels like 1200 can trigger lasting, detrimental metabolic adaptations.

An average person can survive for several weeks without food, but living on a prolonged diet of only bread and water can lead to serious health complications. While this concept has been historically associated with punishment, its extreme nature makes it a dangerous and ineffective approach to modern weight loss or detoxification.

According to a 2024 review, weight gain in the 4-6 month timeframe is common after calorie-restrictive diets. For those asking, "What happens if I just eat less?", the reality is far more complex than simple weight loss and involves significant risks like a slowed metabolism, nutrient deficiencies, and serious health issues.

According to health experts, a 700-calorie diet is classified as a very low-calorie diet (VLCD) and is not recommended for most people without strict medical supervision. What do 700 calories a day look like in reality, and what are the severe health consequences of such extreme restriction?

According to health experts, very low-calorie diets (VLCDs), which often fall below 1,000 calories, are generally unsafe for prolonged periods without medical supervision. This makes understanding why is it bad to eat under 1000 calories a crucial step toward safe and sustainable weight management.

The average adult requires approximately 8,700 kilojoules (kJ) per day to maintain a healthy weight, making a 1,000 kJ figure drastically low and potentially dangerous. The question, "Is 1000 kJ a day good?" therefore requires a careful look at the science and health implications.
