This one is more of a power diet, in the sense that you can only pull it off with a lot of willpower.
The short-term results are bound to be spectacular, but as always, there is no guarantee about the long-term ones. Some diets are very strict on which foods are allowed and which are not, while others focus on achieving a balance between dieting and exercise.
The Ultimate New York Body Plan is an attempt to push both the dieting and exercising to the limit. Calorie consumption is kept at a minimum, while fat burning is maximized through a lengthy program of exercises.
The two-week plan is built around losing some 1,500 - 2,000 calories per day. There are five meals per day which consist of egg white omelettes, lean meat (fish, chicken and turkey), vegetables and salad. Believe it or not, these are the only foods you are allowed to eat under this diet. No alcohol, no bread, no rice, no dairy products, no fruits. It's a tough program and recommended only to those who are sure they can stick to this gruelling experience. The meal plan is supplemented by two protein shakes per day, which is helping your general health, but not your craving for food.
And if the strict dieting is not enough, you are also going to enjoy 45 minutes of cardio-vascular exercise and 45 minutes of cardio-sculpting exercise. That's apt to be a bit rough on those not used to such intense workout. Some people can barely motivate themselves to work out half an hour per day, which is why this diet is rather ambitious to set the mandatory time limit at an hour and a half. I'm not sure that many people are able to stick to this, but I guess that if you really like this diet, then you can soldier on for two weeks.
As you can see this diet is not for the faint of heart and definitely not for the casual dieter. It takes a lot of willpower to refrain from quitting on the third day or so. People who haven't exercised in years and have quite some weight to loose should not attempt the 90-minute work out, because it's simply too much all of a sudden for them. Also, this diet is more of a quick fix because the weight lost during the two weeks will come right back as soon as you're back on regular food.
