It is only in the USA that they regard fibre as a carb. Generally, on this website, reference to grams of carbs is excluding fibre, as fibre has no effect on blood glucose.
Most people who low carb seem to aim for less than 50 grams of carbs per day. I also do this, but struggle some days. Better blood sugars and more weight loss if I can get the carbs lower.
It can also be confusing as some people refer to percentages by weight of food, and some by calories.
For example, 100grams of peanuts might have 50 grams of fat, 30 grams of protein and 10 grams of carbs............so 50/90 = 55% fat . However, that is 450 calories from fat (as 9 calories per gram), 120 calories from protein (4 per gram) and 40 calories from carbs (4 per gram). So percentage calories from fat is 450/610 = about 73%.
I aim for about 80% of my calories from fat = approx. 60% by weight...............hope that makes sense. Can only achieve this by having at least 100ml of double cream every day................yum!
