There are many miracle low-carb eating plans out there but none seem to work as good as the two diets I will talk about in this comparative review.

Both South Beach and Keto diets are effective and even recommended by many nutritionists. Below, you will find their pros, cons, health benefits, and side effects.

South Beach Diet

The South Beach eating plan is a celebrity low-carb diet. However, unlike many other similar diets, South Beach isn’t just about restricting carbohydrate consumption. It is more about choosing the right fats and carbs. This program was developed to help heart patients lower their cholesterol level.


The South Beach Diet is a healthy eating approach that leads to weight loss and a balanced overall lifestyle. What most people like about it is that it provides a different perspective and helps food lovers shed those extra pounds without forcing them to make a lot of sacrifices. Compared to the Keto diet, South Beach is less strict so if you want to eat a certain amount of sugary products and carbs, this might be the perfect choice for your preferences.

How Does It Work?

There are three phases of this diet plan that you must follow. Each of these stages is supposed to serve a certain purpose in your weight loss journey.

1 – The 7-Day Reboot

This first part of the South Beach diet was created to reboot your body as well as your health. During this phase, you will eat low-carb and high-protein foods which will offer you a metabolic boost. Therefore, you will start losing weight quicker than expected, you will burn fat a lot easier than ever before, and it will significantly reduce cravings.

Dieters will eat pre-packaged meals and snacks. One could even say this is a transition phase to the more complex eating plan that will follow.

2 – Steady Weight Loss

During the second phase of the diet, you will continue to lose weight in a steady way which will help you reach your fitness goal. You will be allowed to include the right types of carbs in your daily diets such as whole grains, veggies, and fruits. Moreover, you will keep consuming South Beach pre-made meals. Finally, dieters are encouraged to prepare their own personalized breakfast, lunch and dinner ideas.

3 – You’ve Got This

The final phase focuses on helping people maintain their weight-loss progress without feeling hungry. You are now able to enjoy all types of foods but only in moderation. However, you must continue to apply all the principles of this diet.


  • Each day is comprised of three main meals, two small snacks, and one healthy dessert, all of which are high in protein. So, cheat meals are definitely out of the question.
  • Eat right, prepare customized meals, and learn to make good decisions regarding your daily diet.
  • Don’t give up after phase one, even if you feel a little tired. Remember that this is only temporary. As long as you schedule your meals and plan ahead, you will be just fine.
  • Read all products’ labels without exception. Choose whole foods over highly-processed ones.
  • Be proactive and keep working out to eliminate fatigue.
  • Drink plenty of water and don’t consume more than one single cup of coffee a day.
  • Vitalize yourself with vitamins and supplements. One calcium tablet and one magnesium capsule per day are enough.

Keto Diet

This is another popular low-carb diet that many celebrities have tried in order to achieve or maintain a slim figure and a healthy body. During this eating plan, one must consume a lot of fatty foods while also eating protein in moderation and low-carb products. The main purpose of the Ketogenic diet is to force the body into the ketosis phase which means your organism will burn fat instead of carbs.


The Ketogenic Diet was developed to alleviate symptoms of epileptic children. Soon after its launch, however, it was applied by many people who wanted to lose weight in a healthy way. According to specialists, this eating system offers its followers plenty of health benefits and it might even prevent epilepsy, diabetes, or cancer.

How Does It Work?

Keto diet will change the source your organism takes its energy from. It initiates the ketosis process in which one’s body burns fat rather than carbs and uses it as a fuel. Although keto and South Beach diets have certain similarities, the first one is more restrictive when it comes to carbohydrate intake.

So, when we stop eating carbs and consume fatty foods instead, we will experience a lack of glucose in your system. In the absence of glucose, our liver attracts the body’s fatty acids and then transforms them into ketones which are a well-known energy source.

When our bodies are not in the ketosis phase, our liver tends to consume glucose sourced from carbohydrates so fats will be stored in our cells. This is a tricky thing that can make us gain weight.

Final Thoughts on South Beach Diet vs Keto

No matter what you do, you must remain realistic because there’s no such thing as a perfect diet. It is not a matter of choosing one diet over the other but more a thing of adaptation.

You can try both these diets at first, and then see which one you can follow the longest.

That said… here’s my overall advice:

  1. If You Need Clear Plans and Meals: Go with the South Beach diet here (now 45% off), it does most of the “hard work” of planning meals for you, which is typically where people give up on diets…
  2. If You Want General Guidelines, but Flexibility: Get started with Keto. You will have to do some learning up front, but ultimately it could be a more sustainable track if you invest the energy.
