A study led by scientist Kevin Hall at the <br />National Institutes of Health examined the <br />effects of the keto diet vs. a low-fat, plant-based diet.<br />Out of a group of 20 people, half followed the keto diet and half followed the high-carb, low-fat, plant-based diet for two weeks.<br />After the two weeks, the keto group switched to the plant-based diet and vice versa for another two weeks.<br />When on the low-fat diet, Hall found participants cut about <br />700 daily calories on average vs. 300 daily calories with keto.<br />However, insulin levels on the low-fat diet were "through the roof."<br />Given the short time frame of the study, it's unclear if the keto diet may have produced better results but according to this study, a low-fat diet can be just as effective in helping to lose weight.
