DietDemand ComparesPopular Diet Plans

There are many popular diet programs out there to choose from. However, deciding which one is best for you can be confusing and time-consuming. Additionally, people on these diets tend to have varying results due to a number of personal factors, so reviews and testimonials from all these individuals can be mixed. That’s why we’ve compiled information on popular diet to compare their similarities and differences. This information should help you gain a better understanding of the advantages and disadvantages of some of the most commonly used diet programs.


The South Beach Diet

The South Beach Diet, which exploded in popularity in the mid-1990s and early 2000s, is based on the ketogenic diet which we will get to later. Created by Dr. Arthur Agaston, the diet eliminates carbohydrates and sugars in weekly phases. Eliminating these products from the diet can lead to weight loss, improved blood sugar regulation, lowered levels of inflammation and more. This style of dieting has no time restriction and can become a lifestyle choice.


  • Uses a gradual process to encouragedieters to make long-term changes when it comes to eating habits
  • The diet is very simple to follow
  • No counting of calories needed


  • A possible lack of fiber, b-vitamins and other minerals
  • Can lead to an imbalance of protein and saturated fatsin the diet
  • Many aspects of the diet do not fit into the American Diabetes Association’s dietary recommendations


The Zone Diet

The Zone Diet is a very specific eating regimen that requires a diet that is 30 percent carbs, 40 percent protein and 30 percent fat. It is purported that sticking to this style of dieting will help the body better regulate insulin and shift hormones into balance with the end result being weight loss. Dieters on this plan must focus on portion control and keeping their food group ratios as accurate as possible.


  • Dieters can eat a decent amount of carbohydrates
  • Diets that stimulate insulin production create the feeling of fullness, which limits snacking and food cravings
  • Some athletes say that the diet improves their performance


  • Eating by ratio can be arduous and confusing for dieters, especially when eating out.
  • While no calorie counting is involved, a person must track the grams of proteins, carbohydrates, and fats in each meal
  • No scientific research validates that the 40–30–30 ratio normalizes insulin levels


The Stillman Diet

The Stillman Diet is a primarily protein based option (with some dairy included). Created by Dr. Irwin Stillman, this diet heavily restricts carbohydrates, sugars and many vegetables. Adherence to this diet must be strict, but weight loss is possible.


  • Protein options are limited to lean meats such as veal, lamb, chicken, turkey and seafood. Butter, oil, and margarine are all prohibited.
  • Noted for bringing aboutfast weight loss.
  • Good option for people who don’t enjoy eating vegetables.


  • Eliminates necessary vegetables and fruits that contribute to good health
  • The diet may contain too much protein, which is can be dangerous for those with kidney disorders, high-cholesterol and more.
  • Can cause digestive issues due to lack of fiber


Ketogenic Diets

The ketogenic diet is well-known for its effectiveness when it comes to weight loss. This plan starts to work when carbs and sugars are significantly reduced or eliminated from the diet. This triggers a phenomenon called ketosis, which means that the body is now burning off fat for fuel, rather than consumed carbohydrates. Dieters will usually replace carbs with high-fat foods and proteins, which may have some disadvantages if the ketogenic diet isn’t medically supervised. As the body adjusts to the keto diet, some supplements such as B-12 may be needed for energy and other low-carb induced symptoms. We recommend that medically-supervised weight loss plans should be combined with ketogenic diets, so that doctors can monitor patients for not only successful diet results, but also signs of other health problems.


  • Weight loss results are often quick and noticeable
  • Relatively easy to follow in comparison to more complicated diets


  • Dieters can suffer from low-energy, sleep disturbances, muscle fatigue and more.
  • Not ideal for athletes and muscle-builders.
  • A high-fat diet can increase one’s bad cholesterol levels
