When I diet I follow a high protein, medium carbs, low fat diet. The fat in diets is mostly from unhealthy and you want to minimise it ofc you can’t have no fat but keep it as low as possible. You need carbs for day to day energy so don’t cut them out, just balance. I usually go for 45% protein, 35% carbs, 20% fat, follow a macro like this forces you to follow healthy eat, you could only reach such targets by having vegetables, lean meat, fruits, whole grain alternatives, no junk, etc.
