I’m coming to the conclusion that the fitness industry love of nutrient timing is mostly about selling protein shakes at the juice bar in the gym.
My life is a 60 hour work week, a long commute, keto at 20 net carbs, cardio, lifting and walking. I skip breadfast Monday - Friday, eat nothing on Saturday and never snack. So it’s Sunday morning, 36 hours since the last food. Instead of eating early as usual, then lifting, I spent a few hours sipping coffee and doing food prep then down to the basement for an hour session of lifting. I measure progress in reps added to sets. I got more of those this morning than usual while feeling noticable hunger. For training after work I always prep dinner, then train, then eat which seems to increase motivation during the training. I see no evidence that training well fasted or hungry effects fitness progress.
