You’re living in the past brother. Sorry….
Science, supplementation has evolved. Plenty of enzymes, minerals in supplements now, arguably just as much as food, if not more.
For guys taking in 5,6,7K cals it’s much easier to get in a quick 1-2K with a shake.
Plenty of guys on here making shakes who have gained size. I believe
@danieltx ? has 7K cals a day and some are from large
shakes
@heavyhitter has been 260 on shakes.
There’s a guy on IG, someone help me out here, I forget his name. He does chicken shakes. Chicken breast in a blender.
Ronnie has a video from back in the day where he’s doing like 6 scoops of protein in a blender with milk and chocolate milk powder.
Cbum does a breakfast shake of oatmeal, banana, yogurt, protein powder and berries I believe. He won 3 Olympias.
I don’t see anything wrong with having a PWO shake, and a real meal 1 hour later. Plenty of pros do this.
Or a combination of shakes and real food.
Unless you have science to say otherwise….
