Question: What is the zone diet, how does it work, and how effective is it in reducing weight?
Answer: The Zone diet is a low-carbohydrate and low-fat diet that puts the macro-nutrients into a ratio of 40 to 30 to 30. So, you have each meal be part-carbohydrate, part-protein and part-fat: 40 percent carbohydrate, 30 percent protein, 30 percent fat. It's a lifestyle approach; it is reasonable because there is sufficient research behind it, so that I can feel comfortable as a doctor to recommend it.
It provides adequate nutrition; it provides the protein and fat and minerals and vitamins and energy that your body needs. And for many people it does fit into their lifestyle.
And there are actually other products that support the use of that kind of diet, so I think it's a reasonable way to go.
