how much fat grams should man eat
For example, if you are looking to cut some fat for the summer without losing muscle, you can intake 1 gram of protein per pound of body weight, 0.5 grams of fat per pound, and the balance will be carbs. For a 180lb man, that means 180 grams of protein and 90 grams of fat. Assuming a 2,000 calorie diet, that leaves 200 grams of carbs left over (1 gram of protein/carbs has 4 calories, and 1 gram of fat has 9 calories). The percentage breakdown in this example is roughly 35% protein, 45% carbs, and 20% fat.
