A new study found that simply swapping lowfat alternatives for high-fat counterparts (think lowfat milk or yogurt rather than whole), helped people lose an average of 3.5 pounds.
It's a strategy that makes sense...if you do it right. While swapping skim milk (80 calories) for whole milk (150 calories per cup) cuts calories without adding anything more, some lowfat alternatives are not better swaps. Many lowfat and fat-free products replace fat with other ingredients--often sugar and additives. So stick to just trying out low-fat alternatives to whole foods, like milk or yogurt.
