There is this other stuff I have at home been given to us at the 7's comp couple years ago. It's similar to replace, but has some other cool elements to it.
When I get home, I will post the name of it and what it's got in it.
I've made my own shake type for rugby trainings in the past (on the friend's advise who is a nutritionist). Basically it consisted of apple juice (obviously can be whatever you like juice), a bit of rock salt, and one scoop of protein powder. Sip that during the training, plus water.
After training you'd want something like a fruit salad (canned) and a protein shake.
I've managed to keep the weight, got stronger and lost most of the fat!
