The thread title was kind of straightforward though.
Not a lot of meat in, "Vegetarian/ vegan camp food".
Ah, it's BcUK, the threads and conversations ramble around
100kg isn't that heavy these days. I know a heck of a lot of folks in that range and sort of up to 125kgs.
I think it could be hard work to keep that weight though if working really hard and not getting enough calories. It's not just protein the body needs, but it needs calories.
How you get them is up for dispute, especially if you're limited in what you can eat.
OP says he can't eat meat or tofu and isn't fond of fish.
Vegetarian / vegan food's easy enough.
Camping though, that means carrying it, and that's another issue.
Dried foods that cook up quickly, like potatoes, couscous, noodles, are all calorie rich, and if you can manage milk, then the full fat dried milk's an excellent source, it will enrich foods very well, and you can make cheese with it too.
Flour makes flatbreads, bannocks, again calorie high, use the dried milk in the mix and you're adding protein.
Dried egg's pretty dire, but if it's cold and you're only going for a couple of days, make up scrambled egg and bag it. Eat it promptly and it'll be fine.
Garlic granules, crispy fried onions, sundried tomatoes, herbs....all lightweight, all full of flavour and easy to add to recipes.
