Reader Question of the Week
Regarding fasted workouts, Chim Richalds asked:
What about for someone who isn’t fat adapted? I take a fairly liberal primal approach which is high in all 3 macros, am I likely to still see the benefits?
Yes, you will see the benefits.
Fasted workouts (and fasts in general) are going to be more difficult to initiate for the average person eating higher-carb. It may be hard to decide to train in a fasted state and actually stick with it. But I’d argue they might even be more important, the more carbs you typically eat.
Fasted workouts supercharge the fat-burner within all of us. I’ve always said that everyone should spend time in a ketogenic state from time to time, even if they’re eating a high carb diet. The best way for a high-carb dieter to reach ketosis is through the occasional (or regular) fasted workout.
Fat oxidation goes up.
Glycogen drops (from utilization). You can’t help but turn to fat for energy.
Mitochondrial function improves. You may even start building new mitochondria that are better at burning fat.
Metabolic flexibility increases. This is the phenomenon of that athlete everyone knows who can eat whatever and still look and feel great. High enough activity levels bestow a superhuman metabolic furnace.
