Iron Gut - Strong Constitution perk question

[Wade]

It says "Buffs from consumables last 20% longer". Does that include when eating any food you will be satiated 20% longer? Or just effects from pills, beer, coffee etc?

[Sir Duckyweather]

I'm fairly certain that part only affects the effects from pills, beer, coffee etc. as you mentioned. However, that's only one part of Iron Gut to boost buff durations. In addition to buff durations, lower food poisoning and dysentery chance, and increased breath underwater, you can see that Iron Gut also reduces food and water loss by half the amount it boosts buff durations (so in your case with +20% longer buffs, food/drink will decay 10% slower). It's a very useful skill just because it does so much.

Being satiated longer isn't technically the same as having slower food/drink decay though, but it's pretty similar in function. How fast you burn through food and drink depends on how much strenuous activity you perform, so if you don't do much you don't need nearly as much food/drink (even without the skill) as when you're constantly working, fighting, running, etc.. Having your sustenance drain at 90% of its normal rate isn't necessarily being satiated 10% longer, I don't think, but it's close enough you could look at it that way.

As above, the perk will reduce food and water loss by 5% per level, as it says in the perk.

That said, Mineral Water or Red Tea that give efficient digestion buff will have their buff time extended, so you can use those to extend your food out even further if you like.

Personally, I like Iron Gun because over a day I can take 3 Blackstrap coffee in the cold or 2 yucca smoothies in the desert, and basically be immune to weather and always have a stamina boost.
