Professor of dietology from South Africa David Raubenheimer is sure: the main misconception when switching to proper nutrition is the rejection of any one product, because neither fatty foods nor sugar by themselves harm the body and do not cause problems with excess weight and related diseases. It's all about imbalance.
Raubenheimer spent in New Zealand from 2004 to 2012 observing animal nutrition, proposing a new approach to healthy eating based on his observations, which is based on evolution and ecology. The body of wild animals itself senses what food it needs at a given time. It is no coincidence that carnivores, whose diet is based on proteins, also eat plant foods from time to time. Animals intuitively find in living nature those foods that they lack in their diet, and that are available in their habitat.
Studies of the human diet have shown that the main thing for people is to consume the required amount of protein. Moreover, the need for it in a modern person is 35% less than that of our ancestors, and is about 20% of the daily diet. Diets with a higher protein content (for example, the paleo diet) can cause serious harm to the body in the future. If the body lacks protein, a person begins to consume more fats and carbohydrates, until then, until he gets enough protein.
Therefore, in any diet, the main thing is to maintain the correct balance. Based on the results of his research, a nutritionist has deduced the ideal diet formula for modern people: 15-25% protein, 20-35% fat and 45-65% carbohydrates.
