There is a lot of conflicting information regarding the best way to lose weight, especially regarding food diets. A recent study compared the different diets and ultimately revealed that there is no significant difference in their efficacy for weight loss. Furthermore, it is recommended to lose weight gradually because rapid weight loss was a risk factor for more rapid and important weight regain. This notion has been challenged by a study that compared the two approaches and demonstrated that the rate of weight loss has no influence on weight regain. Ultimately, the key is to develop strategies that are best suited to the patient, so that he can adhere more easily and maintain his efforts on the long run.
