What is the best diet?
How does it work? By restricting the consumption of carbohydrates, the body starts to use fat to produce energy. According to Atkins, this phenomenon is called ketosis.
Why avoid it? The protein diet has always been criticized for its high-fat content (which can cause cardiovascular problems). In addition, it is a diet low in fiber, vitamins, and minerals. Lack of carbohydrates can cause drowsiness, weakness, and headache.
The consumption of meat (red or white) is prohibited.
How does it work? As a low-calorie diet, vegetarians tend to be thin, healthy and develop fewer diseases, as they have a higher consumption of whole foods, fruits, and vegetables.
Why avoid it? The restricted consumption of proteins, without adopting a balanced diet, can bring losses, such as deficiency of B vitamins and some minerals (iron, vitamin B12 and zinc). To fill the lack of protein, vegetarians often increase the consumption of cheese, milk, and carbohydrates, which can contribute to weight gain.
Diet restricted in fats
This diet calls for the banning of any and all types of fat from food. Both animals (bacon, butter, meat) and vegetables (soy, canola, corn and sunflower oils) should be avoided.
How does it work? If each gram of protein or carbohydrate provides 4 calories, each gram of fat provides more than twice as much: 9. Therefore, the tendency is that the lower consumption of fat will lead to greater weight loss.
Why avoid it? All elements are indispensable for the proper functioning of the organism. Even, and especially, fats. The consumption of fats below the recommended compromises some functions of the body, such as the production of hormones.

How does it work? There are no studies that prove that the diet works. Because it imposes restrictions, it causes weight loss.
Why avoid it? Some blood types are more damaged than others. There is a restriction of certain foods (eg meats, beans, milk, and dairy products) that can lead to nutritional imbalance.
The ideal diet is one that does not restrict the consumption of food but seeks to balance it. It should contain 55% to 60% of carbohydrates, 20% to 25% of fats and 15% to 20% of proteins. It is also recommended to eat 20 to 30 grams of fiber per day.
How does it work? The ideal diet should be calculated to lose between 1 and 1.2 kg per week or 4 and 5 kg per month.
Why does it? Each and every diet needs to be individualized and take the individual to food reeducation. It is safe in all nutrients as it is unrestricted.
