The amount of fat grams you should consume daily depends upon what else you eat during the day and how active you are.
For many years, the American Heart Association recommended limiting the amount of fat in our diet. Diets high in carbohydrates and low in fat were thought to be the healthiest.
Now, we know that our emphasis should be on:
- The total calories we get each day (to maintain a healthy weight or to lose weight)
- Eating the healthiest types of fats and carbohydrates
- Becoming more physically active -- with time scheduled for exercise every day
So, you first want to estimate how many calories you should consume daily. It doesnt need to be exactly the same each day, but you do want the average intake over a week to hit your goal.
Remember that each gram of fat has about 9 calories. Protein and carbohydrates have only 4 calories per gram. So consuming a lot of fat -- even healthy fats -- fills up your daily calorie allotment quickly.
Which fats should you choose? Use monounsaturated or polyunsaturated fats. Limit foods that contain saturated fats. And avoid trans fats completely.
