Protein Myth: Less May Beat More for Ageing
There is a particular kind of tiredness that comes from doing everything right. The meal-prepped chicken, the protein shake at six in the morning, the macros tracked with the devotion of an accountant. I have been inside that discipline — Singapore, briefly, when I was trying to build something out of a life that had just come apart. The gym was orderly. The numbers were measurable. Everything else was not.
Which is why I find the new research on protein genuinely interesting rather than threatening. A study published this summer challenges one of the most load-bearing assumptions in modern wellness: that more protein means better ageing. The findings suggest the opposite may be true — that lower protein intake is associated with longer, healthier life, particularly as we move into our fifties and beyond. The mechanism appears to involve a cellular pathway called mTOR, which protein activates. Keep activating it constantly and you speed up cellular ageing rather than slow it. The body, it turns out, benefits from periods of relative protein restriction the way it benefits from sleep — the quieter cycles are where the repair happens.
This does not mean protein is the enemy. Adequate protein protects muscle mass, supports immunity, and matters enormously in older age when loss of lean tissue becomes a real clinical concern. The nuance — which rarely survives the TikTok version — is about *timing* and *quantity* rather than maximisation. The "proteinmaxxing" trend, where people target 200 grams a day as though volume alone is virtue, appears to miss the point entirely.
What the research actually suggests is an argument for variety and cyclical eating rather than relentless optimisation. Mediterranean and traditional Maltese diets, incidentally, have always done this instinctively — legumes, fish, seasonal vegetables carrying the nutritional weight across the week, with animal protein present but not dominant. The old ways weren't primitive. They were, it turns out, calibrated.
The broader lesson is one I keep returning to: the body is not a machine to be maximised. It is something closer to a conversation — it responds to what you give it, yes, but also to what you occasionally withhold.
One thing to try: Pick two dinners this week where legumes — lentils, chickpeas, beans — replace animal protein entirely. Not forever. Just to let the quieter cycle do its work.
