Is there such a thing as good food? Maybe...

A STUDY FOLLOWED 100,000+ PEOPLE FOR 20 YEARS:

...foods that contributed to the greatest weight gain were not surprising. French fries led the list: Increased consumption of this food alone was linked to an average weight gain of 3.4 pounds in each four-year period. Other important contributors were potato chips (1.7 pounds), sugar-sweetened drinks (1 pound), red meats and processed meats (0.95 and 0.93 pound, respectively), other forms of potatoes (0.57 pound), sweets and desserts (0.41 pound), refined grains (0.39 pound), other fried foods (0.32 pound), 100-percent fruit juice (0.31 pound) and butter (0.3 pound).

Also not too surprising were most of the foods that resulted in weight loss or no gain when consumed in greater amounts during the study: fruits, vegetables and whole grains. Compared with those who gained the most weight, participants in the Nurses’ Health Study who lost weight consumed 3.1 more servings of vegetables each day.

But contrary to what many people believe, an increased intake of dairy products, whether low-fat (milk) or full-fat (milk and cheese), had a neutral effect on weight.

I WILL TRY THIS FOR A MONTH OR TWO AND LET YOU KNOW HOW IT WORKS - BUT I AM SKEPTICAL.

HERE'S WHY:

CNN: Twinkie diet helps nutrition professor lose 27 pounds

For 10 weeks, Mark Haub, a professor of human nutrition at Kansas State University, ate one of these sugary cakelets every three hours, instead of meals. To add variety in his steady stream of Hostess and Little Debbie snacks, Haub munched on Doritos chips, sugary cereals and Oreos, too.

His premise: That in weight loss, pure calorie counting is what matters most -- not the nutritional value of the food.

The premise held up: On his "convenience store diet," he shed 27 pounds in two months.

For a class project, Haub limited himself to less than 1,800 calories a day. A man of Haub's pre-dieting size usually consumes about 2,600 calories daily. So he followed a basic principle of weight loss: He consumed significantly fewer calories than he burned.

His body mass index went from 28.8, considered overweight, to 24.9, which is normal. He now weighs 174 pounds.

But you might expect other indicators of health would have suffered. Not so.

Haub's "bad" cholesterol, or LDL, dropped 20 percent and his "good" cholesterol, or HDL, increased by 20 percent. He reduced the level of triglycerides, which are a form of fat, by 39 percent.

"That's where the head scratching comes," Haub said. "What does that mean? Does that mean I'm healthier? Or does it mean how we define health from a biology standpoint, that we're missing something?"

Despite his temporary success, Haub does not recommend replicating his snack-centric diet.
