Guiding Your Patients on Protein Intake: Myths, Needs, and Healthy Choices

Understanding the right amount of protein intake is essential for overall health. Although the market is flooded with protein supplements claiming various benefits, the reality is that most people in the US already meet or even exceed their protein needs. Here’s a concise guide to help your patients navigate their protein consumption.

• Protein Needs:
  • General Requirement: 10% to 35% of calories, or 50–175 grams for a 2,000-calorie diet.
  • Sedentary Adults: 0.8 grams per kilogram of body weight.
  • Aging (40–50 years): 1–1.2 grams per kilogram to prevent muscle loss.
  • Regular Exercisers: 1.1–1.5 grams per kilogram.
  • Weightlifters & Athletes: 1.2–1.7 grams per kilogram.
  • Overweight Individuals: Consult a dietitian for personalized plan.
• Sources of Protein:
  • Healthy Options: Plant sources, lean meats, fish, egg whites, low-fat dairy.
  • Avoid Supplements: Whole foods are more effective than manufactured supplements.
• Consumption Timing:
  • Spread Evenly: 15–30 grams of protein at each meal.
  • Avoid Excess: More than 40 grams in one sitting is not beneficial.
• Supplement Guidelines (if needed):
  • 200 or fewer calories, 2 grams or less of saturated fat, no trans-fat, 5 grams of sugar or fewer.
• Additional Points:
  • Myth Busting: Extra protein does not lead to bigger muscles; exercise is key.
  • Risks of Excess: Stored as fat, can elevate blood lipids, and tax the kidneys.
  • Easy Meal Examples: Banana, yogurt, egg = 19 grams; Chicken, rice, vegetables = 25 grams; Egg, bean burrito, milk = 28 grams.
• Conclusion: Encourage patients to meet their protein needs through whole foods and balanced meals, and to consult with a dietitian if they have specific concerns or needs.
