Ever felt like you're doing everything right with your diet and training but still not seeing the results you want? You're not alone. Dr. Mike Diamonds has been there, too, and he's cracked the code to getting lean—especially when starting at higher body fat percentages.
As a medical doctor with a background in biochemistry and microbiology, Dr. Diamonds transformed his own body before becoming a pro bodybuilder. "I built my physique exactly the same way I've done for my clients over the last decade," says Dr. Diamonds. His scientific approach has helped thousands achieve their fitness goals, and now he's sharing his most underrated protein sources that can easily add 100 grams of protein to your daily intake.
Ready to discover game-changing protein options that no one is talking about? These foods will revolutionize your diet plan and help you build muscle while losing fat.
The Golden Formula for Getting Lean
The science is clear, according to Dr. Diamonds: "To build muscle and lose fat, you need to eat a high protein diet, 30 to 50 grams per meal, multiplied by caloric deficit plus weightlifting." The problem? Most people aren't consuming enough protein throughout the day.
Instead of focusing on the usual suspects like chicken breast, steak, protein powder, and Greek yogurt, Dr. Diamonds is revealing 10 underrated protein sources that can transform your results.

1. Reduced Carb Wraps: The Diet Game-Changer
"I promise you, I would not be in the shape that I am right now without this meal, because it made my diet feel like not a diet," reveals Dr. Diamonds about his favorite reduced-carb wraps.
With 7.6 grams of protein and only 10.7 grams of carbs per wrap (compared to regular wraps with just 3 grams of protein and 23 grams of carbs), these wraps provide incredible nutrition stats. Dr. Diamonds personally gets 30.4 grams of protein daily from these wraps alone.
The versatility is what makes them truly special—add any protein source and you can easily reach 60+ grams of protein in a single meal.
2. Shellfish: Compact Protein Powerhouses
"When you want to pick a snack, there should be at least 10 grams of protein per 100 calories," Dr. Diamonds advises. Shrimp over-delivers with 11 grams of protein per 100 calories.
You only need about 3.5 ounces (100 grams) of shrimp to hit 25 grams of protein, making it perfect for those who struggle to eat large volumes of food. Dr. Diamonds often orders shellfish at restaurants to stay within his macros while feeling satisfied.
Beyond protein, these shellfish contain healthy fats, zinc, vitamin B12, and iron, making them nutritional powerhouses.
3. Biltong: The Ultimate Protein Snack
"In America, you guys call it jerky, in South Africa, we call it biltong," explains Dr. Diamonds about his favorite protein snack. "I like calling jerky the timid version of biltong."
This South African dried meat provides an incredible 20 grams of protein per 100 calories—double Dr. Diamonds' recommended protein-to-calorie ratio. Just 43 grams (1.5 ounces) delivers 20 grams of protein.
Dr. Diamonds suggests replacing typical desk snacks like nuts with biltong for a protein boost, and serving it when friends come over instead of calorie-dense dips.

4. Lentils: Plant-Based Protein Champion
Though Dr. Diamonds admits lentils are his "least favorite option" on the list, he included them for plant-based eaters. Lentils provide 8 grams of protein per 100 calories.
What makes lentils valuable despite the higher carb content is their impressive nutrient profile. "They're loaded with fiber, folate, magnesium, potassium, iron, copper, and manganese," notes Dr. Diamonds, who particularly enjoys them in soup form.
5. Edamame: The Complete Protein Snack
"It's impossible for restaurants when you order edamame to add unnecessary oils and sauces—you just need salt to give it flavor," says Dr. Diamonds about this convenient protein option.
Half a cup provides 17 grams of protein, and as Dr. Diamonds points out, edamame is a complete protein containing all nine essential amino acids our bodies cannot produce.
Rich in fiber, edamame helps control blood sugar and supports digestive health. Dr. Diamonds highlights its versatility: "You can eat it on its own, add it to salads, stir-fries, or in your wraps."
6. Egg Whites: The Lean Protein Source
While whole eggs are nutritional powerhouses, Dr. Diamonds explains why egg whites deserve special attention when trying to get lean: "Four whole eggs contain 28 grams of protein, 2 carbs and 21 grams of fat, which is a total of 312 calories. But if you had eight egg whites, that gives you the same amount of protein, but minus all the carbs and no fats and only 137 calories."
The versatility of egg whites makes them indispensable—scrambled, on toast, in omelets, or even in high-protein French toast. "You have to have it," insists Dr. Diamonds.
7. Smoked Ham and Deli Meats: Convenient Protein
"When I'm dieting and I just need a quick protein source, when I just need to grab something in the fridge, I'll take a pack of these," Dr. Diamonds shares about his go-to convenience protein.
Delivering 16.4 grams of protein per 100 calories, smoked ham and deli meats like chicken and turkey breast are protein-packed options you can take anywhere. Dr. Diamonds recommends adding them to English muffins, toast, burgers, or scrambled eggs.
8. Protein Ice Cream: The Healthy Indulgence
"You have to have protein ice cream in your diet as part of that 20% of flexible foods," advises Dr. Diamonds. "It feels like a cheat code. It feels like you're cheating, but it's even better than a protein bar."
Dr. Diamonds recommends brands like Yasso, Halo Top, Arctic Zero, and Skinny Calm for store-bought options. For homemade versions, he suggests using a Ninja Creamy to transform protein shakes into delicious frozen treats.
"Just because of this, they can stay lean year round," Dr. Diamonds says about his clients who incorporate protein ice cream into their diets.
9. Protein Milk: The Daily Staple Upgrade
"We have milk with almost everything," Dr. Diamonds points out, making protein-enhanced milk an easy way to boost your daily intake. Brands like Fairlife and Barbell offer high-protein milk varieties.
This simple swap works for coffee, shakes, cereal, and any recipe calling for milk. Dr. Diamonds notes that protein milk helped his mother meet her protein needs while recovering from dental surgery.

10. Canned Tuna: The Forgotten Protein Superfood
Dr. Diamonds calls canned tuna "the ugly stepchild" of protein sources, but emphasizes its incredible value: "In just eight ounces of canned tuna in water, you can hit 50 grams of protein."
The versatility is impressive—tuna pasta, tuna with rice, tuna with egg whites on toast, or simply eaten from the can. "Canned tuna is so underrated, and I should probably add it more into my foods," admits Dr. Diamonds.
For improved flavor, he suggests mixing it with fat-free mayo and adding it to rice or various snacks.
Conclusion: Protein Is Your Secret Weapon
Adding these 10 underrated protein sources to your diet can dramatically increase your daily protein intake without feeling like you're on a restrictive diet. Dr. Diamonds emphasizes that consistent protein consumption, combined with a caloric deficit and weightlifting, is the formula for success when trying to get lean.
Whether you're starting at 30% body fat or just looking to shed those last few pounds, these protein options will help fuel your transformation. Try incorporating just a few of these foods into your weekly meal plan and watch as your body begins to change.
