I’ve been on CTL for probably 6 months, but recently went back to the priming phase where you go low carb a whole week. In the core phase, you go low carb 2 days each week. The first day isn’t so bad since you have carbs from the previous day to carry you over, but the second day is tough and my workouts suffer.
I don’t know how people do low carb for months at a time; maybe your body adjusts to burning fat instead of carbs for fuel as you say.
I’ll try green tea, and getting more sleep couldn’t hurt. [/quote]
The priming phase is supposed to be 3 weeks. You likely don’t adapt to fat burning in just one week.
I have not had this experience on CTL. If glycogen is full from your cheat day, you should feel fine the whole next day unless you are doing some ridiculous amount of glycogen-depleting cardio. I hike 2 hours the day after cheat day and feel great. Then I hike 1 hour the next day, feeling reasonable. Weight training both days, followed by Surge as Joel approved in his thread. By the third day, I feel somewhat depleted, but start to take in more carbs on the diet.
So after 6 months, I would say that either you need to go back and get more adapted to fat burning as in the 3 week priming phase, or else tweak the diet for your needs. For example, follow a low day with a high day, then a medium. And/or consider the effects of your training on glycogen depletion.
