im not against low carb
at all, keto or original atkins are not my favorite ways to approach it, but Im very much in favor of certain types of low carb diets, particularly higher protein, diets with moderate carb
restriction... i use low carb, hi - protein for contest prep myself... unfortunately, what pervades much of the low carb world still today, is this belief that
calories do nt matter or
calories do nt count or what you alluded to, that you can have a
calorie deficit and not lose fat... whats really happening is that low carb / higher protein can be a very good way to automatically control appetite and
calorie intake, and is also often important for some peoples health given their metabolic status (not very carb tolerant, etc)... its also unfortunate that many in the low carb community are among the ones to suggest that exercise is a waste of time, etc etc, which is also not true and does great disservice to many who listen... low carb does nt work due to some voodoo or because the law of thermodynamics does nt apply... it works mainly because it controls
calories and for some people, helps them achieve
calorie deficit better than other diets... when folks show up here and suggest «i was in a
calorie deficit but wasnt losing» or «exercise does nt work» thats when we cant help but grimace... or chuckle...
