> If you reduce your overall calories you'll lose weight, you can do that on any diet. That's the only thing that is a scientific fact. Ketosis is valid and supported by scientific evidence. Likewise, people in ketosis can perform endurance exercises for longer periods of time, because they are working off of pure fat reserves. Of course all athletes, short of sprinters, burn a mix of glucose and fat, but people who maintain a ketogenic diet for an extended period of time become better at burning fat, and therefor more accomplished at endurance based activities. None of that is controversial. There is a reason professional athletes, in the right fields, are looking towards ketogenic diets for their performance benefits. There is also the fact that, for many people, ketogenic diets make it easier to consume less calories. To put it another way, an 8oz steak and a loaded baked potato have roughly the same number of calories (around 600). Now imagine an 8oz steak and a side of broccoli, and a loaded potato and a side of broccoli. Which one makes for a more satisfying meal? For most people, the answer is the steak. For what it is worth, I will eat 2-3 stuffed potatoes and not be satiated. (I'll then go and eat a steak to actually have a meal!) Same thing with potato chips. I know very few people who get full eating a bag of chips, even though a bag of chips can have more than half the number of recommended daily calories in it! Ditto for movie theater popcorn. Now I do know people who can get full eating a carb heavy diet, people who have a bowl of ice cream and are like "well that is enough". But given the state of America's waistline, and given how much junk food is sold in stores every day, it is apparent that the majority of people are not satiated by carbs after an appropriate number of calories have been consumed.
