I'm also trying to get more gelatin in my diet. I only weigh 67kg (147lbs for those in the US) so I wouldn't need as much protein or calories as the majority of the people on this forum. I get around 1.3g protein per kg (80+g/day) and so it isn't that hard to stay within reason with protein intake. I mix up my sources too and eat organs, fish etc often so am unlikely to get high amounts of methionine etc.
I try and eat stock every day now for the gelatin and other good stuff, but have no idea how much of it I am getting on a daily basis. I would try gelatin powder but it seems like you would miss out on a lot of the other good stuff in stock?
P.S. The PHD guys do seem to eat a lot of gelatin because they like to use stock and eat boney parts of animals.
