I've only been dieting for 6 days, but I already noticed a pretty dramatic drop in gym performance and I’m trying to figure out if there’s a smarter way to structure my diet.

For context, I’m lifting in a calorie deficit (about 700 calories/day as a 270 pound male) and eating very low carb (under 20g carbs/day). Earlier this month, I was able to reach my lifetime goal of seated shoulder press with 60 pound dumbbells, which is probably my favorite exercise and the only lift I care most about preserving.

All week, I felt noticeably weaker and so I took a rest day yesterday, got plenty of sleep, and repeated my same exact morning routine from earlier this month when I finally hit my shoulder press strength goal on May 8th. (protein shake and banana 30 minutes after getting out of bed then gym 90 minutes later)

If I maintain a weekly calorie deficit of 3500 calories, is it possible to strategically have 1 (or maybe 2) higher-calorie days per week? Something like:

  • Friday thru Tuesday 1000 calorie deficit
  • Wednesday 500 calories surplus
  • Thursday 1000 calorie surplus
  • Do my strength workout on Friday morning after protein shake and banana

Would something like this work? I just grabbed these numbers out of thin air and would appreciate any guidance today on how to maintain strength while losing 1 pound per week. 💪

Yeah, I'm a big keto nut. I started the !ketogenic@discuss.online community. But I'm NOT a high powered athlete or lifter, so I can't personally speak to adaptation recovery.

I became complacent and put dieting as my 6th or 7th priority in life rather than top-3

Yeah, Carb benders are a hazard for me as well.

My reason for asking is because Peter Attia said it took him 3 years to replicate his gym numbers and cardio fitness (like with running or HIIT) when trying to become fat adapted.

Yeah, the Volek and Phinny papers on fat adapted metabolism and endurance athletes are probably the most topical here.

https://doi.org/10.1016/j.metabol.2017.10.010 - Keto-adaptation enhances exercise performance and body composition responses to training in endurance athletes

Compared to a HC comparison group, a 12-week period of keto-adaptation and exercise training, enhanced body composition, fat oxidation during exercise, and specific measures of performance relevant to competitive endurance athletes.

Adaptation does take time (but in the literature I don't see anything mentioned longer then 3 months), there is some small benefit to micro carb loading for endurance athletes even if they are fat adapted (10g carbs when bikers bonk).

I'm not aware of any papers on ketogenic weight lifter performance.

ketogenic weight lifter performance

It seems quite non mainstream for lifters to not be omnivores. Do you know any elite lifters who are carnivores or keto especially strongmen?
