Lack of professional support, overcompensation for calories, and muscle loss are the main factors that make fasting unsuccessful in weight loss.
Fasting, especially methods such as intermittent fasting (IF), has become a popular trend in weight loss. However, many people do not achieve the expected results. Below are the main reasons why fasting for weight loss is often unsuccessful.
Cutting down on food intake radically or fasting only helps to lose weight in a short time, easily gaining weight again.
Lack of professional support and advice
Many people fast without guidance from a nutritionist or doctor. According to Dr. Adam Gilden, University of Colorado, lack of professional support can lead to failure in maintaining a diet and achieving weight loss goals.
Compensate for excess calories during eating time.
Some people tend to overeat during the allowed time, leading to consuming more calories than they need. This makes fasting ineffective in creating the calorie deficit needed for weight loss.
Loss of muscle mass
Fasting can lead to loss of muscle mass if not combined with exercise, especially resistance exercise. Loss of muscle reduces the basal metabolic rate, making weight loss more difficult.
To lose weight and avoid obesity, it is necessary to design a scientific, balanced diet instead of extreme fasting.
Difficult to Maintain Long-Term
Some studies show that while fasting can lead to initial weight loss, many people have difficulty maintaining this diet long-term, leading to weight regain.
Not for Everyone
Fasting is not appropriate for everyone, especially those with a history of eating disorders, pregnant or breastfeeding women, and people with specific health problems. Implementing fasting without considering your individual health condition can cause side effects.
Fasting can be an effective weight loss tool for some people, but it is not the right solution for everyone. For best results, consult a nutritionist or doctor before starting any diet.
