You cannot gain muscle and lose weight just from drinking shakes, you have to put in the effort. That said, don't take protein shakes, a lot of them are filled with nasty stuff these days and they don't contain that much protein anyway. Chicken is the best source of protein, do workouts and eat chicken.
Protein shakes are viable but they are just used for convenience, it's easier to carry around a drink a t the gym than a slab of meat in a box. But, just put in the effort to eat chicken more, tis cleaner that way.
I'm just saying protein shakes AREN'T as GOOD as many people think. They're there for conveneice, however many people are convinced they're products from the heavans that'll make you look like arnold schwarzenegger in a few month.
They are indeed full of crap, and only really suitable for people taking roids, as their metabloism is then fast enough to need the barrage of protein and all the rest. If you're not doing the roids and down the gym for half or each day then don't bother as you'll prob just give your kidneys a bashing.
Protein shakes are essentially waste products. They all originate from the cheese making process which whey is extracted. Whey doesn't have much protein itself, so they compress a tonne of it together and add all sorts of metals like aluminium and iodine. So essentailly it's a waste product and people are being convinced it's good for them.
there's absolutely zero point taking protein shakes unless you're hitting the gym pretty hard. If you are, aim to consume about 100g of protein a day through whatever means works for you.
