Caloric restriction leads to shrinkage of water, gut tissue, and liver tissue, contributing to lean body mass loss.

“and i think the other thing is too like i will say going from like 15 to 7 on calipers i did lose some lean body mass but you know my relative strength didn't really change so what's likely is you know a lot of people don't realize lean body mass is not the same thing as muscle mass lean body mass is all non-fat tissues that's skin bone organ weight all that stuff and including your body water and a lot of i think what we see with lean body mass loss is — water gut tissue liver — those those tissues shrink in response to caloric restriction — and so yeah i think most people don't appreciate the glycogen the amount of glycogen you can lose and how much water tracks with glycogen so you lose let's say you lose half your glycogen volume you take the mass of that multiply it by three to four that's the total mass that's lost given the water as well”

“see with lean body mass loss is um water um gut tissue liver um those those tissues shrink in response to caloric restriction uh and so yeah I think most people don't appreciate the glycogen the amount of glycogen you can lose and how much water tracks with glycogen so you lose let's say you lose half your gly iogen volume you take the mass of that multiply it by 3 to four that's the total mass that's lost given the water as well not to mention the plasma loss that comes with plasma contraction”
