Protein Shakes necessary?

[Swat Runs Train]

I weigh 70 kilograms. How much protein should I have?

I go to school and this is what I have-
Recess- small can of tuna, yoghurt and juice
Lunch- medium.large can of tuna slices + chicken pieces or steak pieces
After school- go gym
Dinner- red meat such as lamb chops etc.

154lbs so around 154 grams of protein every day, the meals you mentioned would probably only be around 100 grams, hard to say without exact measurements of how much you're eating of each.

You could benefit from 2 shakes a day to get that extra 50 grams or so., or of course you could simply add another meal in there wherever to make up for that.
