Food Choices & Protein Knowledge
Learn how to make smarter food choices and understand the fundamentals of protein nutrition.
The fundamentals — in six cards
Everything you need to understand protein without a biochemistry degree.
What is protein?
Protein is a macronutrient made of amino acids — the building blocks your body uses for muscle, enzymes, hormones and immune function.
Why protein matters
It preserves muscle during fat loss, keeps you full for hours, supports recovery, and stabilizes blood sugar better than carbs or fat.
How much do you need?
Aim for 1.4–2.2 g per kg body weight. Higher end for fat loss and muscle gain, lower end for maintenance.
Animal vs. plant protein
Animal sources are complete and highly bioavailable. Plant sources need variety (legumes + grains) to cover all amino acids.
Common myths
High protein does not damage healthy kidneys. You don't need shakes right after training. More than 40 g in one meal is absorbed just fine.
Common mistakes
Skipping breakfast protein, relying only on shakes, ignoring fiber, and underestimating calories from 'healthy' protein snacks.
The best high-protein foods
A short list of staples you'll find in every well-stocked, protein-focused kitchen.
Chicken breast
Lean, versatile, ~31 g protein / 100 g
Salmon & tuna
High protein + omega-3 fats
Eggs
Complete protein, cheap, easy
Skyr & cottage cheese
Slow-digesting, low fat
Lentils & beans
Plant protein + fiber
Tofu & tempeh

Protein per 100 g — at a glance
Animal vs. plant protein
Animal protein
- Complete amino acid profile
- High bioavailability
- Rich in B12, iron, zinc
- Higher saturated fat (some cuts)
- Less fiber
- Environmental impact
Plant protein
- High in fiber & micronutrients
- Lower saturated fat
- Sustainable
- Often incomplete alone
- Lower bioavailability
- Needs variety
High-protein snacks
Smart grocery tips
- Read labels — aim for foods with more protein than sugar per 100 g.
- Buy frozen chicken, fish and berries — cheaper and long-lasting.
- Skip 'high protein' marketing on cookies and drinks — check the number.
- Stock staples: eggs, skyr, oats, rice, lentils, canned tuna, frozen veggies.
Frequently asked questions
How much protein per meal is optimal?
Aim for 25–45 g of protein per meal spread across 3–4 meals a day for the best muscle protein synthesis response.
Are plant-based diets enough for muscle building?
Yes — with enough total protein and variety (soy, legumes, grains, seeds). Soy and pea protein are complete plant sources.
Is too much protein bad for you?
For healthy adults, high protein intake (up to 3 g/kg) is safe and does not damage kidneys according to current research.
What's the difference between Skyr and Greek yogurt?
Skyr typically has more protein (10–12 g / 100 g) and less fat than most Greek yogurts, making it ideal for fat loss.
Do I need protein shakes?
No. Shakes are convenient, but whole foods should cover most of your daily protein. Use shakes only to fill gaps.
What are the best foods for fat loss?
Lean, high-volume, high-protein foods: chicken breast, white fish, skyr, cottage cheese, eggs, tofu and lots of vegetables.

Frequently asked questions
Per gram, yes — animal protein tends to be more complete and leucine-dense. But a well-formulated plant blend (pea + rice, or a varied plant diet) reaches the same result at a slightly higher total intake.
