The advice you got thirty years ago? It kept you alive. That’s it.
Most current public health guidelines are designed to stop you from collapsing. To prevent deficiency. They are the floor. Not the ceiling. A new review in Frontiers in Nutrition argues we are aiming too low.
Dr. Chris Macdonald from Cambridge University wrote the piece. He thinks we should aim for thriving. Not just surviving.
The gap is huge. Between staying alive and living well.
The Protein Gap
Look at the UK guidelines. They are based on sedentary people. People who do very little. Just enough protein to avoid getting sick.
But most people are not sedentary ghosts.
Macdonald says several groups need substantially more protein. Athletes. Pregnant women. And anyone getting older.
Here is why:
– Satiety: Protein fills you up.
– Thermic Effect: Your body burns energy just digesting it.
High-protein diets help with fat loss. Yes, really.
What about plant-based diets? It works. Vegan bodybuilders prove this every day. It just takes planning.
High-protein diets are compatible with plants if you think about your meals.
Moving Matters
Exercise rules need the same shake-up.
Current advice keeps you from dying early. Fine. But what if you want to stay sharp? What if you want independence?
Macdonald points to evidence linking activity to better mental health. Stronger cognition. Slower decline.
Aerobic exercise helps. Resistance training helps. Together? They are powerful.
Why mix them? Because the combination targets both the mind and the body. It builds resilience.
Not Just for the Aesthetically Pleasing
Society has a stereotype. It thinks high protein and hard workouts are only for people obsessed with “abs.” Beach bodies. Superficial goals.
Wrong.
It is not about how your arms look. It is about how long you can stand up. Play with grandchildren. Remember their names.
We normalize aging poorly. We call it “Father Time.” An inevitability.
Macdonald disagrees.
What we see as inevitable decline is often just a non-evidence-based lifestyle taking its toll.
Sitting on the couch makes you fragile. Standing up makes you resilient.
He proposes two tiers of guidance. The old one for minimum survival. A new one for optimal health.
Do you want to avoid disease? Stick to the old rules. Do you want a good life? Read the new evidence.
It is not too late. But you have to start.
