Frequently Asked Questions
Understanding Your Protein Needs
Protein is an essential macronutrient that plays a crucial role in building and repairing tissues, producing enzymes and hormones, and maintaining muscle mass. Your daily protein needs depend on several factors including your body weight, activity level, age, and health goals. Understanding your optimal protein intake can help you maintain muscle mass, support recovery from exercise, and achieve your health and fitness objectives.
Why Protein Requirements Vary
The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight per day for sedentary adults. However, this is a minimum requirement to prevent deficiency, not necessarily optimal intake. Athletes, older adults, and those with specific health goals often require significantly more protein to support their needs.
Factors That Influence Protein Needs
- Body Weight: Larger individuals generally require more protein
- Activity Level: Exercise increases protein needs for muscle repair and growth
- Age: Older adults may need more protein to prevent muscle loss
- Health Goals: Building muscle or losing weight affects protein requirements
- Health Status: Recovery from illness or injury increases protein needs
- Pregnancy/Lactation: Increases protein needs for women
