Bryan Johnson's caloric intake was reduced to 1,950 calories per day, leading to fat loss.

“Reduced caloric intake 2,150 from 2,250”

“Increased daily caloric intake to 2250 calories, up from 2000. Goal: increase facial fat.”

“I did an alligraphed uh fat transfer and so what I did is I took a donor uh because I don't have any fat on my body to inject on myself otherwise I and so I injected at my face and my face is swollen from that”

“So, I'm on caloric restriction. So, I eat 2,000 calories a day and that has caused me to be pretty lean. So, uh I'm Yeah. So, some facial volume and there's two ways to restore I guess not two ways to restore facial volume.”

“today we are at one of our partners clinics working on Project Babyface I've been trying to restore volume to my face from my caloric restriction diet we're going to use a fat transfer”

“Next is we decided to increase my daily caloric intake going from 1,950 to 2,250. And we were probing, can we increase my calories while also maintaining the same biomarkers and also putting on more fat. It worked. I gained 15 lbs, just under 7 kg, and that helped revolmize my face.”

“And so my caloric intake was 1,950 calories, substantially less. This caused me to lose a lot of fat including in my face.”
