But according to the International Society of Sports Nutrition, it won’t. Two groups of resistance-trained and semi-fit men were put on the same training schedule. Half of them followed a 'Western diet' (55% carbs, 25% fat, 20% protein), and the other half followed a keto diet (5% carbs, 75% fat, 20% protein). Both groups consumed the same number of calories. After 11 weeks, not only did participants in the keto group lose more body fat, they also gained more lean muscle mass.
It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. It's unclear, however; how long these effects last.
There are vegetables that are high in carbs and others low in carbs. The keto diet recommends sticking to the ones low on carbs but encourages you to eat a lot of them. Best vegetables are all green ones to make it easy. And vegetables that grow above the ground (e.g. lettuce) are always better than the ones that grow below the ground (e.g. potatoes)
