It's difficult, if you are just starting out looking for a diet that works for you, to know where the truth lies in this debate; if the scientists can't sort it out then how are you going to? The plain truth is that you'll need to educate yourself, weigh up the arguments, then follow your own best judgement. My experience has been largely positive but you will, no doubt, have heard of friends having problems on low keto kenetics carbohydrate diets for one reason or another. There is no such thing as a miracle diet and most of them are just variations on a theme but all keto kenetics-type diets are based upon a very specific principle and that principle has been demonstrated to induce weight loss in many people. Perhaps you should try to base your opinion on the available evidence and not on anecdotes. It's your body and your health, after all.
