I am in the supplement industry.But I will say this I literally live on protein powder.I swear to god if you could follow me around for a day you would see I drink 4-5 protein shakes a day.You see I have my own company, so I don't have time to eat, or even get something to eat.So what I do is I drink protein powder, and eat oatmeal and rice with it.
Right now its 12 pm and I have already drank 2 protein shakes, and I am getting ready to eat some food.
If it wasn't for protein shakes I would never get anything done.When you work 12-16 hours a day, your cant stop to eat 7-8 times per day.So I drink 4-5 protein shakes, and eat 3-4 meals.I still weighs 255lbs, so the protein shakes must be working
