What Is The Best Diet To Lose Weight?

The cycle of the constant search for weight loss, the perfect body and frustration when the goal is not achieved is a process experienced by many people. Much of the frustration comes from trying to follow very restrictive diets without follow-up or with unattainable goals. The scientific literature has concluded that no ideal diet for weight loss exists, especially in overweight or obese individuals. The success of a diet is the execution, so the best diet is the one that will be done well, without holes or slips.

Low Carb/Low Carb Diets

Low carbohydrate diets proportionately restrict carbohydrate intake and increase protein and fat consumption. Diets are low carb when you consume less than 40% of calories from carbohydrate-rich foods. For example: following a diet of 1500 calories per day, the maximum daily intake of carbohydrates will be 600 calories. The remaining 900 calories will be divided between proteins and lipids, which can be 30% lipids and 30% proteins or 20% lipids and 40% proteins.

Industrialized, refined or ultra-processed products such as grains, sugar and dairy products are excluded.

Zone Diet

Developed by Dr Sears, the diet is structured by 40% carbohydrates, 30% proteins and 30% lipids. However, the quality of each macronutrient is very important for implementing this diet. The focus is on low-starch carbohydrates, lean vegetable proteins like fish or poultry, and fats from olive oil, avocados, or nuts. The zone diet also suggests consuming plant-based proteins such as tofu and tempeh.

South Beach

It is a diet with several stages and many restrictions, so it isn’t easy to maintain adherence for a long period. Despite providing rapid weight loss, it is not easy to keep the lost pounds off.

It is based on consuming seasonal and local products such as whole grains, fruits, fermented dairy products, lean meats and fish. Proteins must be present in all meals, in animal or vegetable form, such as beans, soy or nuts.     

Low-Fat Diets

For a long time, it was believed that to lose weight, it was necessary not to consume fat. With the development of science, it has been seen that many lipids are essential for the proper functioning of the human body. However, many low-fat diets have responded well, especially in people with heart disease. Another favourable factor for low-fat diets is that this nutrient is more caloric than other macronutrients. For example, 10 g of sugar has 38 calories, while 10 g of oil has 88 calories.
