Good evening,
I hope this isn't a silly question, but why do we play with decreasing/increasing protein intake when slowing down/speeding up metabolism, given that carbohydrates are the ones that speed up metabolism? I was under the impression that we usually start with proteins as the basis for determining the rest of the macronutrients, i.e., proteins and fats, which is why I'm confused that proteins would be specifically decreased/increased when it might make more sense to adjust the carbohydrate ratio.
Thank you very much in advance for the answer.
When manipulating the speed of metabolism, it is important to differentiate which part of the metabolism you wish to influence:
A change in the proportions of energy substrates primarily affects the rate of energy metabolism, that is, the rate of energy production.
A change in the amount of protein intake primarily impacts the balance of anabolic and catabolic processes, thus influencing the speed of metabolism in a different way than carbohydrates and fats, and also in other systems of the organism.

Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.
He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.
In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
