Q: how much fat do you need daily

A: I recommend 20 to 30% of your daily calories come from fats. So if you eat 2000 calories per day, then you want 400-600 of them to come from fats which equates to around 45-65 grams of fat per day. The key is to eat healthy fats and not junk ones -- see my Nutrition article for list of healthy foods.
