She's but a wee lass
Enzymes are protein, and any proteins are broken down to amino acids in digestion, so I don't think it matters what sort of proteins they are.
The high-protein vegan foods are pulses - peas and beans. It's quite possible to get easily enough protein for normal living with an ordinary vegan diet - I don't know about heavy bodybuilding. (It's vitamin B12 that's the real problem for vegans.) It's easy to look up protein compositions of various foods: here is a brief list.
Problem with vegans is not only are most non-animal food sources naturally low in protein, but what protein they do hold does not contain the full range of essential amino acids. I don't know the figures off the top of my head, but I know vegans have to spread their protein diet out to get the full range, i.e. they can't just eat 50g of protein from beans and expect that to be enough. They need protein from nuts, beans, grains, etc.
Let's put it this way. Why don't you do a scientific study and have people eat "just" 3 normal meals a day and see how many actually gain lots of weight. If can prove this silly theory rather than base it off what happened with your brother then I'll shake your hand. Until then please don't try and spout this as fact.
just to add some shit to your idea there...3 meals, proportioned, and some exercise.... the skinny little fuckers (like me :D) will bulk up and fill out, the fat bastards, will drop pant sizes and gain weight as muscle is more than fat.... for proof I offer any single basic training class in the any of the armed forces.# meals on schedule, all controlled proportions, and plenty of exercise.It seems to me the experiment for the most part is already done and continues on every few weeks in one branch or other of the military.
Search youtube for running raw for a good example of what I mentioned.
Anyways, I would gladly do the scientific research, if I could, alas I can't. Perhaps in the future.
I would really love to test out this theory, but unfortunately I do not know anyone underweight that could keep up the diet for even a week =/
Nor do I have time to monitor people to make sure they're actually following through.
Apparently they can get the stuff that protein is broken into from Raw veggies and fruits as long as they aren't cooked. I think the guy on the running raw program is 220 pounds or something all muscle.And I believe he said he only gets 20-30g of protein a day
