High-Protein Eating: Practical Strategies for Every Meal

Muscle protein synthesis (MPS) — the process of building and repairing muscle tissue — is stimulated by an acute dose of protein. Most research suggests a threshold of approximately 20–40g of high-quality protein per meal to maximally stimulate MPS. Eating 10g at breakfast, 15g at lunch, and 80g at dinner provides roughly the same total as 35-35-35, but the first approach under-stimulates MPS for most of the day.

This has practical implications: spreading protein intake relatively evenly across meals (rather than concentrating it in dinner) supports muscle maintenance better, particularly important for people over 50 where anabolic resistance (reduced MPS response to protein) makes adequate, distributed protein intake even more important.

A 75kg adult targeting 150g daily protein across three meals needs approximately 50g per meal — which is achievable but requires intentional planning, particularly at breakfast where most people fall far short.

Animal proteins provide complete, highly bioavailable protein. Protein content per 100g cooked: chicken breast (~31g), tuna (~30g), salmon (~25g), eggs (~13g per egg), Greek yogurt (~10g/100g), cottage cheese (~11g/100g), beef mince lean (~26g).

Plant proteins require more planning but can fully meet requirements. Protein per 100g: tempeh (~19g), edamame (~11g), tofu firm (~17g), cooked lentils (~9g), canned chickpeas (~9g), seitan (~25g). Plant proteins are generally less bioavailable than animal proteins, so slightly higher total intake is beneficial.

Protein per calorie can be a useful frame when managing total calories. Egg whites, plain Greek yogurt, white fish, shellfish, and cottage cheese all provide high protein relative to their calorie content — useful for people wanting to maintain a calorie deficit while hitting protein targets.

Breakfast is where most people's protein intake fails. A typical toast-and-orange-juice breakfast might deliver 5–10g. Getting to 30–40g requires intentional protein sources.

Practical 35g+ breakfasts: three eggs scrambled with 100g Greek yogurt on the side (35g); two eggs with 200g cottage cheese and berries (34g); a protein smoothie with 30g whey or soy protein, 200ml milk, and a banana (35–45g); overnight oats made with 200ml milk, 50g oats, 30g protein powder, and Greek yogurt (35–40g).

For those who cannot face large breakfasts: a smaller meal (Greek yogurt with nuts, eggs on toast) can still reach 20–25g, supplemented by a mid-morning protein source (e.g., a handful of edamame, a hard-boiled egg, a protein shake).

Meal assembly is often more practical than cooking from scratch. A high-protein lunch can be built from pre-cooked or ready-to-use ingredients: a tin of tuna or sardines over greens with olive oil and lemon; Greek yogurt with mixed nuts and fruit; eggs (boiled the day before) with hummus and vegetables; cottage cheese with sliced cucumber and a handful of seeds.

For dinners with minimal active cooking: batch-cooked chicken portions reheated with a jar sauce and rice; baked salmon with roasted vegetables (25 min total); scrambled eggs with smoked salmon and sourdough; tofu stir-fried with frozen vegetables and rice (20 min).

• Tinned fish (sardines, mackerel, tuna): 20–25g protein, zero cooking
• Greek yogurt (full-fat, 200g): ~20g protein
• Batch-cooked chicken: reheat in 3 min, 30g+ protein per serving
• Eggs (2): 12–14g protein, versatile, quick
• Cottage cheese: high protein, low calorie, no cooking

A complete protein contains all 9 essential amino acids in sufficient quantities. Animal proteins are all complete. Among plant proteins, quinoa, soy (tofu, tempeh, edamame), and the combination of rice and beans are complete or near-complete sources.

The concept of 'protein combining' — pairing incomplete proteins at the same meal to form a complete profile — is somewhat outdated. The liver maintains a pool of amino acids from food consumed throughout the day, so as long as a variety of plant proteins are eaten across the day, essential amino acid requirements will be met without precise meal-by-meal combination.

Leucine is the key amino acid for stimulating MPS, and plant proteins are generally lower in leucine than animal proteins. Eating slightly higher total protein from plant sources compensates for this. Tempeh, soy, and lentils are among the better plant sources of leucine.
