Fat should comprise 20 to 35 percent of your daily calorie intake. If you eat 2,000 calories per day, your fat intake should range from approximately 44 g to 78 g of fat per day. Most of your fat intake should be in the form of unsaturated fats, such as nuts, seeds, fatty fish and avocados. Your saturated fat intake should not exceed 10 percent, or 22 g per day. Trans fat should be limited to no more than 1 percent of total fat intake, or approximately 2 g per day.
If you consume 50 percent of your energy intake from carbs and 20 percent from protein, aim to eat 30 percent of your calories from fat, which is equivalent to 40 grams when following a 1,200-calorie weight loss diet and 53 grams of fat when consuming 1,600 calories per day.
