Many fad diets eliminate food groups or focus on certain foods, causing nutritional imbalances. This can cause vitamin, mineral, and protein deficits, harming health.
Extreme calorie restriction, prevalent in unproven diets, can impede metabolism as your body conserves energy. This makes weight loss tougher and might cause fast weight gain when normal eating begins.
Some diets ignore underlying health concerns and cause major problems. Diets heavy in fat and low in carbs can harm persons with heart or kidney disease.
Fad diets cause rapid weight reduction from water loss, not fat loss. This quick loss of water weight can cause dehydration, especially if the diet excludes fruits and vegetables, which contain water and electrolytes.
Rapid weight loss can cause muscle loss without proper diet and protein intake. Losing muscle mass reduces strength, endurance, and metabolism, making weight reduction harder.
Strict diets can have a major psychological impact. If diet outcomes are disappointing, solitude, food fixation, worry, and sadness may occur.
Constipation, diarrhea, and other digestive difficulties can result from unbalanced diets. Continuously following such diets can cause persistent gastrointestinal issues.
Fad diets can cause obsessive eating or food phobia. Developing eating disorders like anorexia or bulimia may rise.
