What Should I Eat to Get More Protein? Best Sources, Swaps, and Strategies

The average adult eats 60 to 80 grams of protein per day, but research consistently shows that 1.2 to 2.2 grams per kilogram of body weight — 96 to 176 g for an 80 kg person — is optimal for muscle preservation, satiety, and body composition (Phillips and Van Loon, 2011, Journal of Sports Sciences). Closing that gap does not require supplements or extreme dieting. It requires knowing which foods deliver the most protein per calorie and making a few strategic swaps.

This guide ranks the best protein sources, shows you practical substitutions, and gives you a per-meal strategy to hit your target without overhauling your entire diet.

How Much Protein Do You Actually Need?

Goal	Protein Target (per kg body weight)	For 70 kg Person	For 85 kg Person
General health	0.8-1.0 g/kg	56-70 g	68-85 g
Weight loss (preserving muscle)	1.6-2.2 g/kg	112-154 g	136-187 g
Muscle building	1.6-2.2 g/kg	112-154 g	136-187 g
Endurance athlete	1.2-1.6 g/kg	84-112 g	102-136 g
Older adults (60+)	1.2-1.6 g/kg	84-112 g	102-136 g

The 0.8 g/kg RDA is a minimum to prevent deficiency, not an optimal target. A meta-analysis by Morton et al. (2018, British Journal of Sports Medicine) confirmed that intakes up to 1.62 g/kg maximized muscle gains when combined with resistance training, with diminishing returns above that point.

High-Protein Foods Ranked by Protein Per Calorie

This is the ranking that matters most when you are trying to increase protein without increasing calories. Protein per 100 calories tells you how efficiently a food delivers protein:

Food	Protein per 100 kcal	Protein per 100 g	Calories per 100 g
Chicken breast (cooked)	18.8 g	31 g	165
Turkey breast (cooked)	19.1 g	30 g	157
Shrimp (cooked)	20.2 g	24 g	99
Cod (cooked)	19.5 g	23 g	105
Egg whites	21.3 g	11 g	52
Greek yogurt 0% fat	16.9 g	10 g	59
Cottage cheese (low fat)	16.7 g	12 g	72
Tuna (canned in water)	22.4 g	26 g	116
Whey protein isolate	24.3 g	90 g	370
Lean beef sirloin (cooked)	15.3 g	29 g	190
Pork tenderloin (cooked)	18.5 g	26 g	143
Tofu (firm)	11.5 g	17 g	144
Lentils (cooked)	7.8 g	9 g	116
Edamame	9.6 g	12 g	122
Chickpeas (cooked)	5.5 g	9 g	164
Milk (skim)	10.0 g	3.4 g	34
Almonds	3.6 g	21 g	579
Peanut butter	4.3 g	25 g	588

Notice that nuts and nut butters, often promoted as "protein-rich," actually deliver very little protein per calorie. They are fat sources that happen to contain some protein.

Practical Protein Swaps You Can Make Today

These are simple substitutions that increase protein without requiring new recipes or cooking skills:

Current Choice	Swap To	Protein Gained
Regular yogurt (150 g) — 7 g protein	Greek yogurt 0% (150 g) — 15 g protein	+8 g

The Protein at Every Meal Strategy

The most effective way to hit a high protein target is to ensure every meal and snack contains a significant protein source. Research by Mamerow et al. (2014, Journal of Nutrition) found that distributing protein evenly across meals stimulated 24-hour muscle protein synthesis 25% more effectively than consuming the same total protein in an uneven pattern.

Per-Meal Protein Targets

Daily Target	Per Meal (3 meals)	Per Meal (4 meals)	Per Meal (5 meals)
100 g	33 g	25 g	20 g
120 g	40 g	30 g	24 g
150 g	50 g	38 g	30 g
180 g	60 g	45 g	36 g

What 30 g of Protein Looks Like

To make this tangible, here is what approximately 30 g of protein looks like from different sources:

Food	Amount for ~30 g Protein	Calories
Chicken breast	100 g (small breast)	165
Greek yogurt 0%	300 g (large bowl)	177
Eggs	4 large	310
Tuna (canned)	115 g (1 can)	133
Cottage cheese	250 g	180
Whey protein	1 scoop (35 g powder)	130
Salmon	150 g (medium fillet)	312
Lean beef	100 g	190
Tofu	175 g	252
Lentils	330 g cooked	383

Plant-Based Protein: How to Hit High Targets Without Meat

Plant proteins are lower in leucine and often lack one or more essential amino acids individually, but combining sources throughout the day solves this (Young and Pellett, 1994, American Journal of Clinical Nutrition). You do not need to combine them in a single meal.

Best Plant Protein Sources

Food	Protein per 100 g	Complete Protein?	Best Combined With
Tempeh	19 g	Yes (soy)	Grains for variety
Edamame	12 g	Yes (soy)	Standalone or with rice
Tofu (firm)	17 g	Yes (soy)	Vegetables and grains
Lentils	9 g	No (low methionine)	Rice, bread, or grains
Chickpeas	9 g	No (low methionine)	Tahini, grains
Black beans	9 g	No (low methionine)	Rice, corn tortillas
Quinoa	4.4 g (cooked)	Yes (all EAAs)	Beans or tofu
Seitan	25 g	No (low lysine)	Soy sauce, beans
Pea protein powder	80 g per 100 g powder	Nearly complete	Any meal
Hemp seeds	31 g	Nearly complete	Smoothies, salads

Sample High-Protein Plant-Based Day (130 g protein)

• Breakfast: Oatmeal with pea protein powder, hemp seeds, and berries (35 g protein)
• Lunch: Tofu stir-fry (200 g tofu) with rice and edamame (38 g protein)
• Snack: Hummus with whole grain crackers + soy milk (15 g protein)
• Dinner: Lentil curry (250 g lentils) with quinoa (35 g protein)
• Evening: Soy yogurt with pumpkin seeds (10 g protein)

Common Protein Mistakes That Keep You Under Target

Mistake 1: Counting Carb-Heavy Foods as Protein Sources

Peanut butter, hummus, quinoa, and nuts all contain protein, but their primary macronutrient is fat or carbs. A tablespoon of peanut butter has 4 g protein and 8 g fat. Do not rely on these as primary protein sources.

Mistake 2: Protein-Heavy Dinner, Protein-Light Breakfast and Lunch

Many people eat a small breakfast (5-10 g protein), a moderate lunch (15-20 g), and a large dinner (40-50 g). This is the least effective distribution for MPS. Front-load protein by adding a protein source to every meal starting with breakfast.

Mistake 3: Thinking Protein Bars Are the Answer

Most commercial protein bars contain 10 to 20 g of protein alongside 20 to 30 g of sugar and 200 to 300 calories. For the same calories, you could eat 200 g of Greek yogurt (20 g protein) with berries and get more protein, more micronutrients, and more volume.

Mistake 4: Ignoring Protein Quality

A 2019 systematic review by Berrazaga et al. (Nutrients) confirmed that protein quality — measured by amino acid composition and digestibility (DIAAS score) — matters for muscle outcomes. Animal proteins and soy score highest. If you eat primarily plant-based, increase total protein by 10 to 20% to compensate for lower digestibility.

Nutrient Breakdown: Protein Goals in Context

Daily Calories	100 g Protein	130 g Protein	160 g Protein
1,500 kcal	27% of calories	35% of calories	43% of calories
2,000 kcal	20% of calories	26% of calories	32% of calories
2,500 kcal	16% of calories	21% of calories	26% of calories
3,000 kcal	13% of calories	17% of calories	21% of calories

Notice that hitting high protein targets at lower calorie levels requires a higher percentage of calories from protein, making food selection more important.

Frequently Asked Questions

What is the easiest way to add more protein to my diet?

The single easiest change is adding a protein source to breakfast, where most people fall shortest. Swapping cereal for oats with whey protein, or toast with butter for toast with eggs or cottage cheese, can add 20 to 30 g of protein to your day without any other changes.

Can I eat too much protein?

For healthy individuals with normal kidney function, protein intakes up to 2.2 g/kg (and even higher in short-term studies up to 3.3 g/kg) show no adverse effects on kidney health (Antonio et al., 2016, JISSN). If you have existing kidney disease, consult your doctor.

Is whey protein better than food protein?

Whey is not superior to whole food protein for muscle building when total intake is matched (Schoenfeld and Aragon, 2018). Whey is simply more convenient and calorie-efficient. Use it to fill gaps, not replace whole food protein sources that provide additional micronutrients.

Do I need to eat protein immediately after my workout?

Not immediately, but within roughly 2 hours. The post-exercise MPS window is real but wider than the old 30-minute myth (Schoenfeld et al., 2013). If you ate protein 1 to 2 hours before training, you have ample time to eat afterward.

What is the best protein source for weight loss?

Foods with the highest protein-to-calorie ratio: chicken breast, turkey breast, white fish, shrimp, egg whites, and Greek yogurt. These deliver the most protein per calorie, maximizing satiety while minimizing calorie intake.

How do vegetarians get enough protein?

Soy products (tofu, tempeh, edamame), legumes (lentils, chickpeas, black beans), seitan, Greek yogurt, eggs, and plant protein powders make it possible to hit 1.6+ g/kg on a vegetarian diet. It requires more planning than an omnivore diet but is entirely achievable. Track with Nutrola to confirm you are hitting targets across the day.
