There will always be some misinformed sections suggesting that protein is harmful for you and it will affect your kidneys and liver
Here are some pointers established by the researches and findings by studies done on protein intake in strength athletes, bodybuilders, and healthy population:
1. You need to consume 1.2 to 1.6 grams of protein per kilo of your body weight to retain lean body mass in a normal healthy population and avoid the risk of sarcopenia due to old age.
2. To maximise adaptations to resistance training aka lifting weights, individuals need to consume protein in the range of 1.6 to 2.2 grams per kilo of body weight when not dieting, i.e. eating in a caloric deficit.
3. There is no anabolic window that requires you to run to the locker room and gulp down a protein shake right after your last set. As long as you are eating adequate protein for the day and evenly distributing it in meals, you need not worry about the anabolic window.
4. If your goal is maximal muscle gain, it is a good idea to split your protein intake into meals containing 0.4 to 0.55 grams of protein per kilo of body weight into 4 to 5 meals per day. That means, a daily protein intake of 1.6 to 2.2 grams per kilo of body weight.
5. When eating in a caloric deficit aka dieting, a higher protein intake of 2.3 to 3.1 grams per kilo of Fat-Free Mass (FFM) is suggested to retain maximum lean body tissue or muscle mass. Note that this is fat-free mass and not total body weight.
6. There is no maximum protein your body can digest in a meal. It is always better to split the protein intake into 4 to 5 meals for the day but this frequency can be lower or higher depending on other lifestyle factors. In the end, it comes down to what suits you better.
7. Long-term high-protein diets in the range of 2.4 to 3.3 grams per kilogram of body weight do not have detrimental effects on blood lipids, liver or kidney function in the healthy resistance training population.
8. Athletes on high-protein diets reported more dietary satisfaction, better mood, adherence, and higher muscle retention during a fat loss phase when compared to those on lower protein diets.
