@tbonedriz96 I am not on TRT. Years ago, we ran a caloric restriction longevity experiment

Partially SupportedBryan Johnson's testosterone level was 832 ng/dL when tapering off TRT, with SHBG of 76.

Partially SupportedA 25% caloric deficit experiment was conducted, and TRT was proactively introduced as a precaution against potential testosterone drops.

Partially SupportedA 10% caloric restriction (2,250 kcal/day) protocol, without TRT, can maintain natural testosterone levels above 700 ng/dL.

Partially SupportedThe 25% caloric deficit experiment was ended because Bryan Johnson became too skinny.
