I drank a quart of skim milk and ate a can of tuna fish within a half hour of every weight-lifting session”
That’s probably close to 100 grams of protein...more than most supplements. And cheaper, probably, also. VEry smart.
If I recall, the milk was app. 36 grams and the tuna app. 17 grams, but I may be off.
I don’t think I would have knowingly taken 100 grams, which would have been too much.
The tuna is dense and moves slowly, so your body has lots of time to process and absorb the protein.
