No foods are banned but some need to be eaten in moderation; if done correctly, you shouldn't feel hungry
Cons
Allows consumption of saturated fat; some studies suggest that the diet could contribute to osteoporosis, high cholesterol, kidney stones or gout due to the increased consumption of protein; side effects of ketosis can include: nausea, headache, mental fatigue and bad breath; side effects of Induction phase include: headaches, dizziness, weakness, fatigue, leg cramps and constipation; doesn't offer full meal plan packages like the Zone; doesn't emphasize that exercise is vital for weight loss; leaving ketosis stage can cause you to regain weight

Theory
The idea behind the Atkins Diet is that when you drastically reduce carb-rich foods from your diet, your body enters a metabolic state of "ketosis" where it will start to burn fat for energy instead of carbs (in the form of glucose).
The Zone Diet promotes the idea of food not as "a source of calories but as a control system for hormones." By eating the right food in the correct proportions, the body will reach a metabolic state where it is operating at "peak efficiency". You not only lose weight, but you feel great, mentally and physically.
How It Works
Developed by physician and cardiologist Dr. Robert Atkins, the Atkins Diet dramatically restricts the consumption of carbohydrates, while emphasizing an increased consumption of protein, fat (including saturated fat) and leafy vegetables. The Atkins plan includes 4 main phases, during which time the goal is to find your Atkins Carbyhydrate Equilibrium (ACE). Your ACE is the daily amount of carbs you can consume without gaining or losing weight. The 1st phase lasts 2 weeks and is the most restrictive with a carb intake limited to 20 net grams per day. It is designed to switch your body to a metabolic state of "ketosis" and kick start your weight loss. The 2nd phase lasts until you are 5 - 10 pounds from your goal weight. During this phase, you will gradually increase your daily net carb intake to determine how many net carbs you can consume and still maintain a healthy weight loss of 1-2 pounds per week. In the 3rd phase, you will determine your ACE, and, in the 4th phase, you will learn how use the good habits you've acquired in the previous phases to make permanent lifestyle changes.
Created by biochemist Dr. Barry Sears, the Zone Diet controls dieters' food intake using a "food block" system, which assigns values to different foods. For example, 1 food block could equal 12 spears of asparagus or 1 ounce of chicken or 1/3 teaspoon of olive oil. Most women are able to consume 11 food blocks a day, while most men will be allowed 14. Eating in the right proportions is also essential on the Zone Diet. Each meal should be 40% carbs, 30% protein (low-fat), and 30% of healthy fat. When putting together your plate, 1/3 of it should be filled with a low-fat protein (3 oz for women or 4 oz for men), and the other 2/3 of it should be filled with low-GI carbs (ex. vegetables, lentils, beans, whole grains or fruit). You can then use a "dash" of heart-healthy monounsaturated fat (ex. olive oil, canola oil, macadamia nuts, and avocados) on top. Finally, the Zone requires keeping a food journal where you track what you ate and how you felt after 4 hours. If you aren't hungry and your mind is clear, your body is in The Zone.
Calorie Intake
The Atkins Diet doesn't require calorie counting, but some dieters felt that the calorie intake was more restrictive than they had anticipated.
Women will consume an average of 1100 calories a day, and men will consume an average of 1400 calories a day.
