Protein is the single most important nutrient when you’re trying to lose weight while staying strong. It keeps your metabolism active, helps your body repair tissue, and protects your lean body mass—the muscle that keeps you healthy, independent, and energetic. When we lose weight, we want to lose fat, not muscle. Losing muscle (called sarcopenia) can make us weaker, more tired, and even raise the risk of falls and memory problems as we age.
The Rule of Thumb: “10 per 100”
A good protein source gives you about 10 grams of protein for every 100 calories or less. That means you’re getting plenty of muscle-building fuel without taking in too many calories.
Aim for 20–30 Grams per Meal
Your body uses protein best when it’s spread throughout the day. Most people do well with 20–30 grams of protein at each meal, which keeps your body supplied with what it needs to repair and maintain muscle—especially after exercise or during weight loss.
How Efficient Is Your Protein Source?
(Calories per 10 grams of protein — lower numbers are better!)
How to Use This Information
- Foods with 100 calories or less per 10 grams of protein meet the “10 per 100” goal.
- Lower numbers mean more efficient protein—more protein with fewer calories.
- Lean meats, fish, egg whites, yogurt, and protein shakes are all top performers.
For some foods, though, the volume is so large that they aren’t realistic as your main protein source. For example, six cups of broccoli may have 10 grams of protein, but that’s a lot to eat! Instead, think of vegetables like broccoli or beans as bonus protein that adds fiber and nutrients to your meal.
Combining smaller portions—such as a serving of broccoli alongside eggs or lean meat—creates a protein-dense, low-calorie meal that supports both weight loss and muscle maintenance.
Quick Tips for Success
- Build each meal around a protein source, then add veggies and healthy fats.
- Distribute protein evenly—20–30 grams at breakfast, lunch, and dinner.
- Aim for 80–120 grams daily, depending on your body size, goals, and activity level.
- Stay hydrated and move! Protein works best when paired with water and activity.
