The recommended amount of protein intake depends largely on body weight, age, activity level, and specific health conditions. Generally, for an average sedentary adult, the recommendation is about 0.8 grams of protein per kilogram of body weight per day. For example, a person weighing 75 kilograms (165 pounds) should consume about 60 grams of protein daily. If the person exercises regularly or is older (40-50+ years), protein needs increase to about 1.1-1.7 grams per kilogram of body weight per day. For athletes or those involved in intense physical activity, intake may go up to around 1.2-1.7 grams per kilogram. Consuming more than 2 grams per kilogram might be excessive unless under specific athletic or health guidance. In summary:

• Average sedentary adult: ~0.8 g/kg body weight
• Over 40-50 years old or moderately active: ~1.0-1.2 g/kg
• Regular exercise or strength training: ~1.1-1.7 g/kg
• Excessive intake above 2 g/kg generally not recommended without supervision

For more precise personal recommendations, factors like weight, age, activity level, and health should be considered, ideally with a healthcare or nutrition professional's guidance.
