Semi-realistic Regeneration and corresponding Increased Consumption

If someone's going to create a write up that involves costs fatigue, I don't see why talking about it is off topic. But whatever.

In high school I worked out 3-5 hours per day and ate 6000 kcal per day. And that level left me athletic but nearly without body fat. I'm sure actual athletes ingest and burn even more each day. So i think your assumption was flawed.

Yeah, right now I need about 3kcal per day or I become extremely weak and disoriented. In high school I needed about the same amount. Also when I was unloading/loading trucks and doing asset protection/bodyguard work. I may be big, but I have a very high metabolism.

If we're verging into FP-cost builds anyway, it seems like an on-target comment aimed at your post.

So you'd probably have a requisite of a boosted liver and kidneys if you want to go this route.

Hmm. Regeneration of hit points in exchange for a buildup of toxins in the blood seems like an interesting mechanism. That being said, a boosted liver is right behind the corner for our inventor, and kidneys are not far behind. Talk about incentives.

This doesn't sound as bad. At a minimum, extra drinking for replacing lost fluids (e.g. blood loss) is seemingly much easier than consuming as much food. But getting rid of extraneous fluids where they're harmful - I'm not sure how exactly that should be done; I'm inclined to believe this will be one of the major contributors for shifting one step closer to Unusual Biochemistry, but not all the way.

Ultimately recommending an IV drip is definitely in the alpha-version description of the biomod.

But you need more than just energy - you need all the nutrients, because that's what people are made of and you'll need to rebuild things.

I don't recall the precise numbers, but IIRC ('normal') sugars don't provide an enormous storage efficiency advantage, so might need to think of something else. Quick wiki check gives sugars 17MJ/kg, while fats get 37.

Even ethanol has only 26. Though a hacked metabolism that can safely handle lots of alcohol and use its energy to fuel ATP production would be amusing.

We'll handwave how the nanites align your tissues correctly and keep them that way while healing without you being strapped in place.

If you've had major tissue damage (fire, chemical burns, the kinds of trauma that takes flesh right off you even if it's not a GURPS amputation that you need Regrowth for) then you need to magic that material out of somewhere. And the logical place for that is your other bones and muscles.

The most obvious way to store the reserves is extra-heavy bones and excess "unsupported" muscle mass that is dismantled by the nanites and relocated to where it's needed.

Hmm. Needing to consider the difference between cutting/impaling and destroying damage types seems like a bit complicated for the game I'm running. But the fact that the former can be modest in requirements is a plus.

You're the OP. I just didn't want it derailed with "This sucks! Change it!" which Costs Fatigue seems to always devolve into.

You're the first one to bring up the FP cost build (in reply to the LFP ideas), not Patrick.

I was suggesting sugars because you specified "not fat", but mobilizing fat reserves has more potential for liver failure. Malnutrition causes mobilization of fat, which can choke the liver, leading to fatty liver, and then we're back to liver failure again. Plus pressure of your engorged liver on your other abdominal organs and the enormous amount of heat being produced by your liver struggling to process everything (which is wasted calories and also gives you a fever).

I was very specifically speaking about Costs FP as it stands in RAW (which is contentious). That's it.

Oh well, I was hoping for something that is better than fats, but I guess that's not much of an option. Not with anything resembling mammalian biochemistry, it seems. I'll have to break out the bio-alchemy then. And liver upgrades.

Since you're talking about nanites, other options would be things artificial sources, like a battery pack or more high-energy reactions that would be dangerous to do right in the circulatory system but could be done in little "reactor units" distributed around the body. By reactor I mean chemical reactor, not nuclear - I don't think you want RTGs in your body at any TL :D
