Question:

What's more important for weight loss—counting fat grams or counting calories? — S. Green, MD

Anne Coulston

Answer:

 

Weight loss can be boiled down to one simple principle: Burn more calories than you eat. Basically, it doesn't matter if the calories come from fat, protein or carbohydrates, but there are a few things you should keep in mind before you throw your fat counter away:

1. Fat contains nine calories per gram compared to four calories per gram for carbohydrate and protein.
2. Eating a diet full of low-fat foods, such as lean meats, poultry, fruits, vegetables and whole grains may be more satisfying than eating the same amount of calories from high-fat food. Consider that one small fast-food hamburger with all the trimmings has as many calories as a turkey sandwich almost twice as big.
3. Remember that fat-free foods often use carbohydrates to make up for lost fat and end up with the same number of calories.
4. Another reason to watch your fat intake: Diets high in saturated fat have been linked to an increased risk for heart disease, stroke and some forms of cancer.
