I agree that diet has a much higher impact on fat loss than exercise by a large margin. If I just sit around and do nothing all day (very rare), I’ll burn 2,000 kcal. If I have my most intense weight day, roughly 45 mins (including rest periods), I burn around 500 kcal (according to FitBit).
I’ve seen excellent results with following a keto WOE and until recently, was doing IF and EFs. Just trying to give myself an edge.
