Depends on why you are counting.
Counting total calories is helpful to maintain body weight. Counting fat is helpful to reduce your risk of heart disease and cancer.
It might be easier to keep track of the grams of fat you eat each day. To determine how many grams of fat you should eat, try the Healthy Body Calculator® and include your weight goal.
Another figure you can track is the percent Daily Value (% DV) for the amount of fat in the foods you eat. This number is on food labels listed by the grams and calories of fat in the food you eat. Add up the percent fat Daily Value for the servings of foods you eat. When you have reached 100%, you have reached the recommended amount of fat in a 2000 calorie My Plate plan which is estimated for the average person to meet their Recommended Dietary Allowance (RDA) but not your individual nutrient needs based on your age and gender in the RDA.
