How Much Protein Do You Actually Need? (A Dad's Guide)
Protein advice online swings between "you barely need any" and "drink four shakes a day." Both are wrong. The research is actually pretty settled, and the numbers are simple enough to remember. Here is what a training dad actually needs, what it looks like on a plate, and how to hit it without spending a fortune.
The honest numbers
If you lift weights and want to build or keep muscle, aim for 1.6 to 2.2 grams of protein per kilogram of bodyweight per day. For an 85kg dad, that is roughly 135 to 185 grams. Anywhere in that range works, so pick the low end and stop stressing.
If you are mostly sedentary, you need less. Around 1.2 g/kg keeps a desk-bound body ticking over. But if you are reading this site, you are probably training, so budget for the higher range.
Punch your own weight into our calculator and it will do the maths, then split the total across your day.
Why it matters more after 30
From your 30s onward, you slowly lose muscle unless you actively fight for it. The process is gradual, but it compounds. Less muscle means a slower metabolism, weaker joints, and a harder time carrying kids, shopping, and yourself up the stairs at 60.
Two things push back: resistance training and enough protein. Older muscle is also a bit less responsive to each meal, which is one more reason the 1.6 g/kg floor matters more at 38 than it did at 22.
What 150g looks like in real food
Big daily numbers feel impossible until you split them into meals. Aim for 30 to 40 grams per meal plus one decent snack, and the total takes care of itself.
A sample day: eggs and cottage cheese on toast for breakfast, a chicken and rice lunch, Greek yogurt with fruit mid-afternoon, and turkey meatballs for dinner. That is around 150 grams without a single shake.
- Breakfast: cottage cheese scramble on toast - about 35g
- Lunch: chicken burrito bowl - about 40g
- Snack: Greek yogurt power bowl - about 25g
- Dinner: turkey meatballs marinara with pasta - about 45g
Cheap protein that actually works
Protein does not have to mean steak and supplements. The cheapest sources per gram are the boring staples your gran cooked with, and most of them meal prep beautifully.
Build your weekly shop around three or four of these and the cost per meal drops fast.
- Eggs - versatile, cheap, roughly 6g each
- Chicken thighs - cheaper than breast, harder to ruin
- Tinned tuna and sardines - shelf-stable and instant
- Greek yogurt and cottage cheese - snacks that do real work
- Lentils and beans - protein plus fiber for pennies
- Whey protein - not required, but the cheapest cost per gram if you like it
The myths you can drop
"Protein wrecks your kidneys." In healthy people, intakes in the 1.6 to 2.2 g/kg range have not been shown to cause kidney damage. The caveat is real though: if you have an existing kidney condition, talk to your doctor before raising your intake. That is not us covering ourselves, it is genuinely different for you.
"Your body can only absorb 30g per meal." Your body absorbs almost all of it; larger meals just digest more slowly. Spreading protein out is convenient, not mandatory.
"You need protein within 30 minutes of training." The anabolic window is more like a garage door. Your daily total matters far more than the clock.
Common questions
›Is 100g of protein a day enough to build muscle?
For a smaller man, close. For most dads over 75kg who train, it is a bit short of the 1.6 g/kg research floor. It still beats the average intake, so treat 100g as a good start, not the finish line.
›Can you eat too much protein?
For healthy people, intakes well above 2.2 g/kg appear safe but offer no extra muscle benefit, so you are mostly buying expensive urine. If you have kidney disease, consult your doctor first. This is general guidance, not medical advice.
›Do protein shakes count as real protein?
Yes. Whey is just filtered milk protein and counts fully toward your daily total. Food first is still smart because it brings fiber and micronutrients, but a shake is a legitimate tool on busy days.
