The standard protein advice most men grew up with was designed for a twenty-five-year-old office worker, not for a body trying to hold onto muscle in its fifties and sixties.
Protein for men over 50 UK guidance has quietly shifted in recent years, and the old rule of thumb most of us default to is now genuinely out of date.
How Much Protein After 50 Actually Looks Like
The generic UK reference intake for protein is 0.75g per kilogram of bodyweight a day, a figure designed to prevent deficiency in a healthy, largely sedentary adult. It was never meant to be a target for anyone trying to preserve muscle.
The British Dietetic Association recommends 1.0 to 1.2g per kilogram of bodyweight a day for adults over 65, rising to 1.2g or higher for those still active. Applying that same logic from your fifties onward makes sense given the muscle loss driving the need starts well before then. For an 85kg man, that works out at roughly 85g to over 100g of protein a day, noticeably more than the 64g the old reference figure would suggest.

Why Protein Per Meal Older Adults Eat Matters As Much As The Daily Total
Total daily protein is only half the picture. How that protein is distributed across your meals matters just as much. In younger adults, muscle protein synthesis maxes out at around 20g in one sitting. Research reviewed by the Gatorade Sports Science Institute found older adults need a larger dose to trigger the same response, somewhere around 30 to 40g per sitting. This is called anabolic resistance.
The practical fix is straightforward: two palm-sized portions of protein at each main meal, rather than one spread across the day with a large gap at breakfast, which is where most people’s intake is weakest.
What This Looks Like On A Plate
A palm-sized portion is roughly 20 to 30g of protein. Breakfast, the meal most UK diets shortchange, could be three eggs with Greek yoghurt on the side. Lunch might be tuna or chicken through a salad plus a pot of cottage cheese. Dinner could centre on a proper portion of chicken, fish, lean beef or a plant-based equivalent, sized generously rather than as an afterthought.
Does Supplementing With Protein Powder Help
You do not need a shake to hit these numbers, whole food gets you there fine. A scoop of whey or a plant-based alternative is a useful way to close a gap on a busy day, but treat it as a backup rather than the main plan, since whole foods bring fibre and vitamins a shake alone does not.
A Note On Kidney Health
If you have kidney disease or another condition that affects how your body processes protein, check with your GP before increasing your intake.
Where This Leaves You
Protein for men over 50 UK guidance has moved past the old one-size-fits-all figure. Aim for 1.0 to 1.2g per kilogram daily, and spread it properly, two palm-sized portions at each main meal rather than one thin portion stretched across the day.
Fix your weakest meal first, usually breakfast, and the rest tends to follow.
