Go Easy On The Fat

New Year, New YOU - Phase 1

While most of us know that consuming excessive amounts of fat will make us fat, we don't all understand exactly why this is true. To implement a successful weight management program, you need a good understanding of fat and why this nutrient makes us fat.

The amount of energy a particular food has depends on the quantity of fat, carbohydrates, and protein it contains. Food energy, both in its consumption and expenditure, is measured in terms of calories. Foods are either made up of fats, protein, carbohydrates, or a combination. A food that contains mostly fat will contain more than twice the calories than a food containing mostly carbohydrates and/or protein. For example, compare a serving of low-fat yogurt to a serving of nonfat yogurt--the low-fat yogurt has quite a few more calories than the nonfat variety because every gram of fat has more than twice the calories of a gram of protein or carbohydrate. Fat contains 9 calories per gram; protein and carbohydrates yield only four calories per gram. Therefore, it is important that you move towards replacing foods high in fat with foods higher in protein and complex carbohydrates.

No more than 25 percent of your total calories should come from fat, fewer than 10 percent from saturated fat, the most damaging form. A recent study of 23 lean men and 23 obese men found little difference in the total number of calories each group consumed. But the obese men consumed, on average, more than 33 percent of their total calories from fat, compared with 29 percent for the lean men. Because the body converts dietary fat into body fat more easily than it converts protein and carbohydrates into body fat, the obese men were storing more fat even though both groups consumed the same total number of calories.
