Funny enough, I’m a big fan of what John Beradi has written about with g-flux
I think creating a calorie deficit with activity and filling it back in with nutrition is a great way to get the most out of a fat loss phase, but I also agree with you in that a “cardio cut” goes poorly in general. I tend to get “stringy” if I attempt that. I like my activity to be low intensity when fat loss is the goal: walking primarily.
