Carbohydrate Timing by Overall Daily Activity
Thomas acknowledges that conventional wisdom says to eat carbs around workouts, but he argues that for resolving insulin resistance, the bigger picture is daily activity level. He uses the leg press isometrics study to underscore how even tiny amounts of contraction massively increase glucose uptake. Sedentary individuals often sit all day and then become moderately active at home, making evening a better time. Conversely, a person on their feet all day (waiter, construction) can handle carbs throughout the day. He also hints at potential sleep benefits from evening carbs for those who are otherwise low-carb all day, but does not expand on that. This timing method dovetails with the carb cycling protocol to further optimize glucose tolerance.
Insulin-independent glucose uptake: contracting muscles can absorb glucose without needing insulin. So when you are on your feet moving, you get a 'mechanical suck-up' of carbs. If you are sedentary, giving carbs when you aren't moving leads to poor uptake and higher insulin demand, worsening insulin resistance. By delaying carbs to the evening when you are naturally more active (household chores, family activities), you align ingestion with periods of higher glucose disposal capacity. For active all-day people, spreading carbs early capitalizes on continuous low-grade movement to clear glucose.
If you are sedentary, it is more ideal to keep it low carb and high protein throughout the course of the day and actually have your carbohydrates allocated to the end of the day because you're not active.
