Hi, my name is Lisa Moskovitz and I'm a registered dietitian and certified in the state of New York, with a private practice on the upper east side. I specialize in weight management, exercise and sports nutrition. And I'll be talking to you about diets First off, we have the Atkins Diet. Everyone knows this diet, it's very popular, and probably most of you have even tried it. What is the Atkins diet? Well, the Atkins Diet was created by a cardiologist, Dr. Atkins, and his philosophy, his theory, was that by reducing carbohydrates, we actually increase our metabolism and our fat-burning process. The more carbohydrates we eat, the higher our insulin levels go. What happens when our insulin levels increase is that we turn off our fat-burning process. So by reducing carbohydrates, we naturally produce less insulin and therefore we increase our fat burning process, which increases our metabolism. This particular diet, like most, is broken down into phases. The first phase is about two weeks long and this is supposed to reduce your cravings, detox your body, and really get you to reduce your carbohydrates significantly so that you set yourself up for weight loss long term. The good part about this diet is that it does promote a low refined carbohydrate diet, and what refined carbohydrates are is anything that has been processed, so cakes, cookies, anything that contains a lot of carbohydrates that cause a dramatic increase in your blood sugars and then of course what goes up must come down. So after your blood sugars decrease, you end up feeling fatigued, experience more cravings ,and that's how you get addicted to carbohydrates. The cons are that it promotes a high saturated fat intake. High amounts of saturated fat are directly linked to heart disease, so I wouldn't recommend it to people with heart disease , and because it happens to be very low in carb, I wouldn't recommend it for highly active individuals.
