Following a very low calorie diet is the best way to lose weight 

While reducing calorie intake can indeed boost weight loss, cutting calories too low can lead to metabolic adaptations and long-term health consequences.

Though going on a very low calorie diet will likely promote rapid weight loss in the short term, long-term adherence to very low calorie diets leads to a reduction in metabolic rate, increased feelings of hunger, and alterations in fullness hormones 

This makes long-term weight maintenance difficult.

Very low calorie diets lead to metabolic adaptations that make long-term weight maintenance difficult.

This is why studies have shown that low calorie dieters rarely succeed in keeping excess weight off in the long term (27Trusted Source).
