Tune in Monday, January 11 to The Doctors to learn 52 tips to help you lose weight.

Forget expensive personal trainers and fancy diet food. If you want a realistic way to shed pounds in 2010, The Doctors and Prevention’s Editor-in-Chief, Liz Vaccariello share their favorite 52 tips for losing weight - one tip for each week of the year.

Even though there are scores of diets on the market, many of them say the same thing: Eat less, move more.

But the recently-released O2 Diet, also being called the antioxidant diet, takes the emphasis off of eating less and exercising and instead places it on the nutritional value of what you’re eating.

Created by registered dietitian Keri Glassman, The O2 Diet focuses on antioxidants, those tiny but powerful substances in food that help rid the body of free radical damage, which has been linked to everything from heart disease and cancer to Alzheimer’s disease and wrinkles. Using the ORAC (Oxygen Radical Absorbance Capacity) scale, a measurement created by the USDA that calculates how well a food protects the body against free radicals, The O2 Diet has you counting ORAC points rather than calories, fat grams or carbs.

But after an in-person visit from Biggest Loser trainer Bob Harper, Erik is ready to get back to his fighting weight to fight once again for his life.
