Ok, so i spent about 10 months doing ULC and intermittent fasting (mostly because i like skipping breakfast). The first two months I lost 25lbs, then i stalled. At the time i was eating as much as i wanted, so i decided to start reducing my caloric intake to see if that would break the stall, but no dice. I even dropped down to around 1300-1500 kcals/day (I’m 6’2″ 265lbs, BMR~3000kcals) for over a month with no weight loss. In fact the only change i noticed was serious losses in strength at the gym. So i came across Kiefer and read both CNS and CBL books. I tried CN for a month at first and I didn’t notice any changes from doing ULC. So at the suggestion of a friend i switched to CBL for roughly 3 months. I loved it, strength returned in the gym and i could handle high intensity workouts (texas method program). But i still had no weight/fat loss (still about 265lbs). Then i went to eating a moderate fat, moderate carb, moderate protein diet (at maintenance for cals) for 4 months with no change in weight, again. I just started doing carb nite again about 3 weeks ago. So far no loss in weight still. I currently eat about 2500 kcals/day, with 60% fat, 35% protein, 5% carbs. I lift weights (modified 5×5 program, centered on bench, squat, and deadlift), I walk about an hour every evening with my daughter (approx. 4.5 miles) and do two HIIT workouts/week on the stationary bike. I’m at around 25% bf but thats just an estimation. Finally, my question is: should I really try to go all out on carb nites to get my metabolism going? or should i keep it pretty clean? i did an experiment by eating a ton of donuts my first carb nite and by the next carb nite i actually dropped down to 264. The next two carb nites i was far more conservative (a potatoe, then a bowl of ice cream) and i jumped back up to 268 this week. Im not sure if doing ULC for so long has stunted my ability to lose weight, but something seems to be amiss. I’ve never had a hard time dropping weight until the last couple years.
