Think of it like this: If you’re putting your muscles through intense workouts, they need more building blocks to recover and grow stronger. This is why athletes generally require a higher protein intake than sedentary individuals.
• Age: As we age, our muscle mass naturally declines, a process known as sarcopenia. Adequate protein intake becomes increasingly important to help maintain muscle strength and function, slowing down this age-related decline. Older adults may need more protein to support their muscle health and overall well-being.
• Goals: Your protein needs will vary based on your specific goals. If you’re aiming for muscle gain, you’ll need more protein than if you’re focused on weight loss or simply maintaining your current health.
• Body Composition: Your body composition—the ratio of muscle mass to fat mass—can also influence your protein requirements. Individuals with a higher muscle mass will generally need more protein to support their muscle tissue.

Recommended Daily Intake (RDI) and Beyond:

The general recommendation for daily protein intake is 0.8 grams per kilogram of body weight, or 0.36 grams per pound. However, this RDI is a baseline for general health and doesn’t account for the varying needs of active individuals and athletes.

Beyond the RDI: Personalized Protein Intake for Performance

To optimize your protein intake for performance, consider these guidelines:

• Active Individuals: Aim for 1.2-1.7 grams of protein per kilogram of body weight daily. For example, if you weigh 70 kilograms, you’ll need 84-119 grams of protein per day.
• Athletes: Depending on the intensity and duration of training, athletes may need 1.2-2 grams of protein per kilogram of body weight.
• Weight Loss: Adequate protein intake can help you feel fuller for longer, making it easier to manage your weight and avoid overeating. Aim for 1.2-1.6 grams per kilogram of body weight.

Remember, these are general guidelines, and it’s always best to consult with a healthcare professional or registered dietitian for personalized recommendations based on your individual needs and goals. They can help you create a protein intake plan tailored to your specific activity level, age, goals, and body composition.
