You are not failing your diet. Your body… is surviving it.
For years we were made to believe that fat loss was a matter of discipline, willpower and caloric deficit. But there is something they didn't tell you: your biology does not negotiate.
In this conversation he reveals why caloric deficit may be destroying your metabolism, how chronic stress and cortisol generate insulin resistance sabotaging your progress — making it almost impossible to eliminate belly fat — and why many women, despite doing "everything right", end up losing muscle, disrupting their hormones and accumulating more weight.
He also explains the key role of the microbiota, rest and strength training in body recomposition… and why punishing your body will never be the solution.
Because maybe you don't need to do more. You need to stop fighting against your own body.
