your friend is right but it's advisable to diversify your protein sources because at the moment relying more than half of your daily protein intake on whey sounds unsustainable. i don't know about kidneys but most people have problems with whey because it has lactose. if you're not lactose-intolerant then you're good.

in bodybuilding everyone obsesses over proteins but actually you need to focus on other nutrients as well (dubbed the "macros"), primarily fats and carbs. the recommended ratio would be carbohydrates: 45-65% of calories, fat: 20-35% of calories, protein: 10-35% of calories. so i hope you don't neglect this.

Also, every individual is different. Some reacts bad to carbs. I feel sluggish with carbs. Fats are no no for me hours before training. So go look for the suitable combo for yourself.

I can't eat anything before working out if not I'll feel unproductive as well so I'll take either Milo or a banana before hitting the gym. I can't really cook so I'm gonna start preparing small meals like sandwiches and depend on outside meal for the rest of the day.Atleast for now

hm... for me. i ll just take a scoop of whey or half scoop of whey with eggs + banana before hitting gym. then normal meal to try hit the macros... means getting chic + egg from chicken rice shop or mixed rice. at nite same. else just drink another scoop of whey during tea time. usually my bulking phase, i add in between main meal like bread..milk... yogurt... 
just protein is not sustainable unless u on keto.... at least for me.. :-P i need carb

Hmm, since this is a related topic, I might as well ask.

What's the appropriate amount of protein for a bodybuilder/strength athlete ? I know that the golden rule is 1g of protein/lbs of bw (2.2g/kg) but I've also read contradictory statements saying that 0.8-1.4 g/kg is adequate.

I personally take 1.2g/kg and I'm asking because I found out that my body does not do well on high protein diets. I normally get stomach aches (I found out it was due to indigestion for eating too much protein too quick). It helps though if I chew more/space out my meals. Should I suck it up and eat 1g/lbs by spacing my protein intake ?

I also noticed that 1g/lbs basically applies to both beginners and advanced trainers. I fail to understand this because given the same weight, they should be quite different in terms of body composition/training intensity, no?

From what I heard, 1g of protein per lbs bw is for maintaining current shape for bodybuilders, of course one does not actually chug down daily amount of protein in one go as your body couldn't process it all in one go, not to mention you're risking yourself for kidney failure. Divide it among meals or between meals is the best way to do it.

As for how much you really need to take daily? it depends, taken for my case that I need to increase my muscle mass I need to rack up my daily protein intake up to 1.4g / 1lbs (Of course, I need to work my ass off). But I would agree on 1g per BW is the basics for beginners, go for it. Happy Gaining.

I thought those 2 are myths?

Am used to have kidney issues back when I'm in college, back then I was taking too much eggs per meal and my body couldn't cope with the drastic protein intakes. These problems subside when I cut down it to a minimum and gradually increasing it at a very slow pace.

Edit:
There's a reason why they measure protein contents in your pee when you're doing medical checkups.

I think your kidney problem could be attributed to other factors rather than or on top of too much eggs? College, stress, sleeping late, maybe? The general consensus seems to be that if u already have kidney problem, high protein diet (not too much protein in one meal) might deteriorate it; otherwise good to go.
And about body couldnt absorb too much protein in one go, there are studies that agree and dont. I just dont think it makes sense. Those Bodybuilders that practice IF can be the living proofs I guess...

You don't need more than 0.85g per lb bodyweight.

Some say more, some otherwise.
