Before you start this diet, consult your doctor. Even though successful on a short run, it is highly controversial. Many health experts claim it has a multitude of negative effects on your health, especially if you follow it for longer than a couple of months. For a more nutritionally balanced and healthier diet, you can try the Atkins 40 diet which is similar to classic Atkins but with more food variety and fewer restrictions.

The Atkins diet has four phases:

1. The first phase lasts for two weeks in which you should avoid carbohydrates and all foods containing them (even in small quantities).We also should avoid fruits and leafy vegetables and a person on a diet should use a variety of supplements to compensate for the vitamins and minerals.
2. The second phase is slowly introducing carbohydrates when you are allowed to consume 15-40 g of carbohydrate per day, depending on the body weight of the patient.
3. The third phase allows consumption of large amounts of carbohydrates that are regulated so they don't affect your weight.
4. The fourth phase lasts for the rest of your life. A certain amount of carbohydrates you can consume is defined and you should stick to it if you want to maintain your desired weight.

Before you start this diet, consult with your doctor. Even though Dukan diet can help you lose weight, many experts consider it unhealthy, not effective in the long run and nutritionally deficient.

Dukan diet is created by Dr. Pierre Dukan and it is comprised of four phases that cycle the types of protein and carbs you consume. The reason for this cycling is to reach into fat reserves for energy and trick the metabolism to effectively burn excess fat.

The four cycles are:

• Attack Phase: You are allowed to eat lean meat, fat-free dairy products, and fish. You are advised to drink an abundance of water. This phase is designed to be followed no more than 10 days.

• Cruise Phase: This phase is all about alternating days when you eat only protein, and days when you eat protein and non-starchy vegetables. Using any kind of fat for preparing meals is strictly forbidden. Drinking lots of water is still required. You should follow this phase for a long as it needs you to reach your desired weight.

• Consolidation Phase: Protein from lean meat is still your main calorie source. But in this phase, you can also eat one portion of fruit, two slices of whole wheat bread, and a piece of cheese (1.5 ounces).Twice per week you can add a small portion of starchy carbs like potato or rice. You can also have two days in a week when you can eat a cheat meal that includes dessert. But then the following day you can only eat protein. For every pound you lost, you should add 7 days to the duration of the consolidation phase.

• Stabilization: You can start eating normally, but one day per week should be a protein-only day.

The diet is designed to be followed in three phases. But, if you have no more than 10 pounds of excess weight, you can start with phase 2. Each phase becomes gradually less restrictive. The focus is on removing bad carbs and fats from your diet and instead start consuming good carbs and fats. Your typical days will consist of three meals, two healthy snacks, and a dessert with a high percentage of protein.

• Phase 1: You have to endure for two weeks without starchy food like bread, pasta, rice, and potatoes. Fruits, milk, yogurt, honey and baked goods are also off the table. Sugar is strictly forbidden. Emphasis is on lean meat, fish, eggs, beans, nuts, and non-starchy vegetables.

• Phase 2: You gradually reinstate fruits, pasta, and bread(whole grain only). You'll pick only one type of carb and combine it with one meal each day for one week. You are advised to wait a couple of days and if there are no noteworthy effects, implement one more healthy carbohydrate. Continue this until you're able to successfully have two or three healthy carbohydrates each day. Phase two will last until you reach your desired weight.

• Phase 3: In this phase you maintain your desired weight that you reached in phase 2. Phase 3 is designed to last for life. No food is forbidden. Instructions recommend eating 3 pieces of fruit daily, 3 to 4 servings of starchy vegetables, and no more than 2 tablespoons of healthy fats, such as olive oil.

Several celebrities made this diet very popular. It has very simple rules. You eat 14 jars of baby food (any kind you want) a day and you are allowed to have only one "real" meal a day that includes lean meat and lots of vegetables. Everything else is banned. And that's it.

This diet is meant to be sustained for no more than 7 days. It is not a diet one would consider balanced or nutritionally sound, but it may help you lose some weight since it is highly unlikely you will eat too much, thanks to the portion control and boring taste. Most people will get sick of baby food after one or two days.

Will all that in mind, it this diet is rather difficult to follow and most people will find it hard to sustain for more than a couple of days. But since it is low in fat, sugar, and salt, it can help you clean your body from toxins and jump-start your weight loss.

Vegetarians and vegans can easily adjust this diet to their preferences.

Flat Belly diet is one of the few diets that advocates increased fat intake as a way to lose weight. Of course, we are talking about healthy fats (monounsaturated fats) you get from olive oil, seeds, nuts, and other plants that high in fat. Saturated fat you get from fatty meats and processed food should be avoided.

You are supposed to eat 4 meals a day, every 4 hours. Meals should have around 400 calories which add up to 1600 calories per day. Every meal should include healthy fats.

For the first 4 days, this diet's main goal is to decrease bloating of your body and  is somewhat rigid since it bans all processed food, vegetables that makes you gassy (onion, legumes), and carbs like bananas, pasta, bread, etc. That can be challenging for most people, but fortunately, it lasts only 4 days.

After that, you switch to more casual diet (but still are not allowed to go over 1600 calories per day and must include healthy fats in every meal) that very much resembles Mediterranean diet.

It is considered healthy for people with high cholesterol, blood pressure or heart disease.

The Cabbage Soup diet is a quick weight-loss diet and its supporters claim you can lose 10 pounds (4.54 kg) in a week. It can be used to lose a couple of pounds before some important event or it can be used as a measure to jump-start your weight loss and then switch to a healthy and balanced diet.

As its title says, you will mostly eat cooked cabbage. You are allowed to add tomatoes, peppers, onions and some other ingredients in your cabbage soup. There are many recipes out there. Each day you will be allowed to eat something other than cabbage soup. Some day it will be a piece of lean meat, other days it will be fruit or low-fat dairy product. Vitamin and mineral supplements are recommended.

This diet will give you only 1000 calories per day,  which is only half of recommended calories for most adults which means you will be hungry all the time and you might struggle with following this diet. Exercise is definitely not recommended while following this diet because your body simply won't have enough fuel.

There are several diet plans that promise you to lose weight if you replace your meals with their specially made cookies. Some of the popular ones are Dr. Siegal's Cookie diet, Hollywood Cookie diet, and Smart For Life Cookie diet.

With this cookies you replace breakfast, lunch and snacks. For dinner you can make a regular meal of your choice, as long as it is healthy. There are various types of cookies, but most of them are high in protein and fiber. Some of them are vegetarian-friendly.
