There is a very simple rule I use for this; not sure how accurate it is, but it works well for me. - Protein - meat - is for repairing/building - Carbs are for fueling - Fats are somewhere in between. Cells membranes are basically fat and fat is also a very clean,dense and "slow" form of energy. Based on your activity level: - Couch potato: Eat very low carb (basically no starches, under 50g per day). - Light activity: Eat low carb (under 100g per day). - Moderate activity: Eat moderate carbs (under 200g per day). I am here, weight training 3 times per week, with 2-3 long walks (about an hour) - High activity: Eat high carb (>200g per day) - Eat between 1 and 1,5 g/protein per kilo. - Adjust fat to achieve your desired calorie intake. For most of us, between 2.000 and 2.5000 kcals/day is a good target. The key here is to stop demonizing carbs/fats and recognize that they have its place in our diet. I have also observed that, regardless of your activity level, starting low-carb when you are obese is a good thing to do, but after 1-2 years, low-carbs diets go against you.
