Study: no 'best' diet or weight loss

PALO ALTO, California (WPVI) -- If you're looking to shape up for spring, don't look for gimmick diets.

A new study says there's no such thing as the "best" diet.

Stanford researchers followed 600 people assigned to a variety of diets.

After 12 months, those following low-carbohydrate or low-fat lost about the same weight - about 12 pounds.

Contrary to some diet claims, they also found a person's genetic makeup doesn't seem to affect whether a certain type of diet will work.

But overall what did make a difference was healthy eating.

They found people who ate less sugar, fewer processed foods and more vegetables lost the most weight.

Here's more from Stanford University.
