2. Highly Restrictive Diets
Crash diets or those that eliminate entire food groups are generally not advisable. While such extreme dietary restrictions can lead to rapid weight loss, they are rarely sustainable and can quickly diminish your motivation. Over time, the lack of essential nutrients and excessive stress on your body can cause intense cravings for unhealthy foods as your body seeks to replenish lost energy. This often results in regaining the weight once the diet is abandoned.
