Here's a great article from one of the fitness industry's biggest names: Tom Venuto

 The big mistake almost everyone is making, even fitness and nutrition professionals who have been blogging about this lately, is that while they are agreeing that it’s nice to have low calorie items on the menu (especially with calories posted), they are calling these low calorie fast food items “healthy choices.”

Some journalists and bloggers have jumped into the fray and cleverly countered…“These new fast food menu items are NOT healthy, they’re only ‘healthi-ER.’”

I think they are both mistaken. This food is not healthy nor is it healthier. It’s only lower in calories. The only way you could say these lower calorie fast food items are healthier choices is in the sense that they can help to reduce total daily caloric intake, if all else remains equal. That could help people lose weight and if they lose weight the weight loss could improve their health. Eating smaller portions of refined carbohydrates or sugars might also be healthier, from a glycemic point of view.
