What’s the most important thing for fat loss? A calorie deficit. What’s the most important thing for muscle gain? Progressive overload, adequate protein and consistency.What’s the most important thing to feel good and help us with our well-being and nourishment? Other than mindset… macros. You can lose weight by just eating one meal a day and you can build muscle by training consistently in the gym, but you won’t feel good doing either of these things if you don’t focus on a getting a decent amount of macros to optimise your health, training and well-being.
