Can a vegetarian diet affect acne? Are there any health benefits to fasting? Dr. Oz tackles these questions and more when he opens up the phone lines and his e-mail inbox to help solve viewers' health conundrums. Joined by his wife Lisa and Dr. Roizen, Dr. Oz also offers insights into why certain individuals don't sweat while exercising, how cardio exercise burns fat and where to find vegetarian sources of healthy omega-3 fatty acids.

Then, Dr. Oz talks with Dr. Daniel Jones, president of the American Heart Association, about The Heart of Diabetes campaign, aimed at raising awareness and educating people about the connection between diabetes and cardiovascular disease.
