Is Ketosis necessary to lose weight?
It’s not necessary to lose weight – all you have to do is take in less calories than you expend and you will lose weight. Most people MEAN that when they want to lose weight ,what they really want to do is lose fat. Many diets reduce calories too much and people do lose weight, but a lot of it is muscle along with the fat. This reduces the person’s metabolism and fat is regained more easily. Being in ketosis means that your body’s primary source of energy is fat (in the form of ketones or free fatty acids). The state of ketosis is believed to be anti-catabolic, minimizing the loss of muscle when dieting. A number of studies that compared several forms of reduced calorie dieting have demonstrated that the least amount of LBM is lost on a ketogenic diet. Also, ketogenic diets tend to accelerate fat loss because when fat is coverted to ketones, it cannot be converted back to fat, and so is excreted.
