well which is it, the calories or the carbs? on pure LCHF you don't need to count calories
It isn't nearly that simple and both play a role. There are many factors which affect obesity, one of which is definitely carbohydrate intake. But it isn't the only one.
It's not like if you never eat carbs you will be lean and ripped even if you eat 1KG of biltong and 1KG of butter per day.
It's both. Eating too much is a problem, it's just far more of a problem if you are eating too many carbohydrates.
