yes, if you are to base your diet off of, for reference let's use 2000 calories, and you make 75% of that fat, then you would lose weight faster if your remaining portion-25%- were mostly of protein, with the smallest part being complex carbs found in certain and mostly green vegetables. If you were to invert the process and use 25% fat, then have the remainder protein with a small portion as complex carbs, you might not lose weight as well if you have just anormal metabolism. There are 3 types of food-carbs, protein and fat- so low carbing is about dereasing your carbs and balancing the other two food parts.
