^ W00t! I was wondering when you'd take that step, given your username and environmentalism
Ironically, I hate it when people say this is the best solution for the environment. Even if everyone somehow went vegan, the planet still wouldn't be able to support an exponentially growing number of humans.
Vegan food is generally poorer in calories (which is great for some people, less so for others), so he might need to eat bigger portions or grab snacks in between meals.
My boyfriend went vegan in January and has managed not to lose any weight, even though he wants to, haha! It's probably because he eats lots of bread and junk food, and doesn't exercise... Carbs under any form are filling -- bread, pasta, potatoes, beans. Tofu is great (and tastes awesome when fried with barbecue sauce), as are meat replacers. These are getting better and better by the way, you can't even tell with some of them.
I'll post some recipes when I get home. The minimalist baker has plenty of good ones though, like this 5 ingredient sweet potato and black bean chilli: https://minimalistbaker.com/5-ingredien ... ean-chili/
I've always had stomach problems due to an insane metabolism. I felt hungry all the time even when I was omni. I still get hungry really fast, but I feel that it's become slightly more manageable on a vegan diet. Not sure why, maybe because I'm lactose intolerant, so I've stopped constantly irritating my gut. In any case, the point is going veg*an doesn't mean feeling hungry all the time, even though some people do struggle with this until they find the right regimen/recipes.
