Protein: why, how much, and what to eat

Protein: The Building Block of a Healthy Life

Protein is one of the most essential macronutrients for overall health and wellness. As a cornerstone of nutrition, it plays numerous critical roles in the body that extend far beyond just building muscle. Understanding protein—its sources, benefits, and optimal consumption—can significantly enhance your health journeys.

Why Protein Matters

Protein serves as the building block for nearly all structures in the human body. It repairs tissues, supports immune function, creates enzymes and hormones, and helps maintain fluid balance. For active individuals, protein aids in muscle recovery and growth, but its importance extends to everyone regardless of fitness level.

The amino acids found in protein are particularly valuable, with nine essential amino acids that our bodies cannot produce independently. These must come from our diet, highlighting the importance of consuming quality protein sources regularly.

Why Protein Matters and How Much You Really Need

As a health coach and fitness professional, one of the most common questions I get asked is: “How much protein do I really need?” Protein is one of the most important nutrients in your diet, yet many people don’t know how much they’re actually getting—or why it even matters.

Let’s break it down.

Why Protein Is So Important

Protein isn’t just for bodybuilders—it’s essential for everyone. Here’s why:

  • Builds and repairs muscle – Every workout you do breaks down muscle fibers. Protein helps rebuild them stronger.

  • Supports metabolism – Protein takes more energy to digest than carbs or fats, which can give your metabolism a boost.

  • Keeps you full – High-protein meals help stabilize blood sugar and keep you satisfied longer.

  • Supports hormones and enzymes – Many of your body’s key processes run on proteins.

  • Supports healthy aging – Adequate protein intake helps prevent muscle loss as we get older.

How Much Protein Do You Need?

The answer depends on your body and your goals.

A simple guideline is:

  • General health: 0.8–1.0 grams of protein per pound of body weight.

  • Active lifestyle / strength training: 1.0–1.2 grams per pound of body weight.

  • Muscle gain or fat loss phases: up to 1.2–1.5 grams per pound of body weight.

Example:
If you weigh 125 pounds and are active, you’d aim for around 125–150 grams of protein per day.

Quality Protein Sources

Quick Reference Guide

  • Highest protein options (20g+ per serving): Chicken, fish, beef, pork

  • Moderate protein options (10-20g): Tempeh, firm tofu, Greek yogurt

  • Lower protein options (5-10g): Beans, lentils, chickpeas, nuts

  • Supplementary protein sources (<5g): Most vegetables, grains

Protein sources vary widely in their nutritional profiles. Here are some excellent options:

Animal-Based: Lean meats (chicken, turkey, lean beef),fFish and seafood, eggs, Greek yogurt and cottage cheese

Plant-Based: Legumes (beans, lentils, chickpeas), tofu and tempeh, quinoa, nuts and seeds

Plant-based proteins often require strategic combining to ensure all essential amino acids are present, making variety particularly important for vegetarians and vegans.

Protein doesn’t have to be complicated—it just has to be intentional. When you prioritize it, you’ll notice more strength, better energy, and improved recovery.

Coach’s Tip: Start by tracking your protein for a day or two. Most people realize they’re not eating as much as they think. Once you see the numbers, it’s much easier to adjust.
