Oh god please don't, it's a terrible idea and recipe for gastric distress.
I've gone too far with protein shakes and felt terrible. I'm a body builder and have used almost all diets as I've bulk and cut. A protein shake only diet is effectively a Protein Sparing Modified Fast (PSMF) - zero carbs, zero fat, but shakes only is just the worst way to do it. Lyle McDonald's "Rapid Fat Loss Diet" is popular PSMF and more sensible. Focus on white fish, lean meats and moderate green vegetable with planned periodic cheat meals. Be in no doubt that it's an extreme crash diet with negative hormonal consequences. If you don't have a compelling reason to crash diet, I wouldn't do it.
The benefits I experienced with a PSMF are similar to keto which is much more sustainable with fat. Once I cut out carbs, my appetite just disappears. Without carbs, I don't get hungry as such, instead I get type of tiredness which indicates I should eat. The desire aspect of eating drops off which prevents overeating.
Doing keto for the first time was brutal for me though. 2-3 weeks of keto-flu - tired and ill feeling. But after adapting it's easy. These days I can snap in and out of keto without noticing any ill effects at all.
After 15+ years of various forms of diet, my main trick for cutting is just to eat less desirable food. Don't buy food I can lose control with. Don't use condiments that make things tasty. That turns out to be easier than portion control with delicious food but it's likely a personal thing.
