Fuel the Performance

For most of my 20's and 30's, I was doing it backwards.

I was training hard — weights, boxing, everything I love — and eating carefully. I thought "carefully" meant disciplined. I thought keeping my portions tight and staying lean was the smart play. I was focused on making weight for my competition, not on what my body needed to do the things I was asking it to do.

What I actually was, was chronically under-fuelled. And it was costing me. My recovery was slow. My attention span across the day was unreliable. I was working hard in the gym and getting diminishing returns, wondering what was wrong with me rather than looking at my plate.

When I finally shifted my framing - from eating for leanness to eating for performance - everything changed. Not just in training, but in how I showed up for work, for the people around me, for the demands of a full life.

That shift is what I want to talk about here.

Nutrition is not a punishment. It is not a negotiation between you and your body. It is the raw material your performance is built from.

The professional who exercises is not eating enough

If you are in your late thirties, forties, or fifties, running a team or a business, training 3-5 times a week, and watching what you eat - there is a reasonable chance you are under fuelling.

It could be that the cafe or lunch room where you normally get your lunch, offer a limited quality of food and limited options. For many of us, the framework most of us grew up with was built around weight management, not output.

Diet culture taught us that less is more. Smaller portions, fewer calories, more willpower. And for a long time, many of us applied that logic to bodies that were increasingly being asked to do more - more professional responsibility, more physical output, more recovery demands - without adjusting the fuel going in.

The result is a gap between what you are asking your body to deliver and what you are actually giving it to work with.

What changes after 35

There are real metabolic shifts that happen in this phase of life, and understanding them matters.

Your body becomes less efficient at synthesising protein. That means the same amount of protein you were eating at 28 produces less muscle repair and maintenance at 42. The threshold rises. If you are not actively accounting for this, you are running a deficit in the one nutrient most critical to recovery, strength, and body composition.

Hormone changes - for women in perimenopause and beyond, and for men with gradual testosterone decline - affect how your body responds to both training and food. Recovery takes longer. Inflammation sits higher. The margin between adequate nutrition and inadequate nutrition gets narrower.

What this means is that the strategy needs to evolve. What worked at 30 is not the right blueprint for 45.

Protein: the non-negotiable

Most of the high-achieving professionals I work with are eating far less protein than their body actually requires. Not because they do not know protein matters, but because the amount required - especially after 35, especially if you are training - is genuinely higher than most people expect.

General guidance for active adults in this life stage sits between 1.6 - 2.2 grams of protein per kilogram of bodyweight per day. For a 75 kg person training consistently, that is between 120 and 165 grams per day. Spread that across three meals and you can see immediately why most people fall short.

Protein is not about getting bigger. It's about repair. It's about keeping the engine running cleanly after you put it under load. Skimping on it does not make you lean - it makes you slower to recover, more fatigued, and more likely to lose the muscle mass that keeps your metabolism working efficiently as you age.

Recovery nutrition: the window most people ignore

What you eat in the period after training is as important as what you eat the rest of the day. Your muscles are most receptive to nutrients in the first hour after exercise. This is when protein synthesis is elevated and glycogen replenishment is most efficient.

Many busy professionals finish a workout, skip straight to a meeting or a commute, and eat something small hours later. The body interprets this as stress. Cortisol stays elevated. Recovery is compromised. The training stimulus you worked for is not fully cashed in.

A post-training meal or snack does not need to be elaborate. It needs to include protein and carbohydrates, eaten within an hour. That is it. The simplicity of the solution is often at odds with how much of an impact it has.

Energy across a demanding week

High-achieving people tend to treat food the way they treat everything else they consider non-essential in a busy week: they defer it, minimise it, optimise it down to nothing. Coffee replaces breakfast. Lunch happens at 3pm. Dinner is the only real meal.

This pattern is disastrous for sustained cognitive and physical performance. Your brain runs on glucose. When blood sugar is unstable - cycling through the spikes and drops that come from under-eating or skipping meals - your focus, decision-making, and emotional regulation all suffer. You are running your best thinking on a nearly empty tank.

Consistent energy across the day comes from consistent fuelling. Regular meals. Adequate protein at each sitting. Carbohydrates timed around your training and your most demanding cognitive work. This is not complicated, but it does require treating nutrition as a legitimate priority rather than something to get back to when things slow down.

You would not expect high performance from a car running on fumes. Your body is no different.

This is not diet culture

Everything I have described here is the opposite of restriction. It is about giving your body what it needs to do what you are asking it to do.

If you are training, leading, building, and showing up fully, you have high energy demands. Meeting those demands is not indulgent. It's intelligent. The goal is not to be smaller. The goal is to be stronger, sharper, and more resilient across a long and demanding life.

When I stopped eating to stay lean and started eating to perform, I gained muscle mass, not body fat. I got stronger. My recovery improved. My energy across the day became something I could rely on rather than manage around. And the training I had been doing for years finally started giving back what I was putting in.

That is what fuelling for performance looks like in practice. And it is available to you too - not through a stricter plan, but through a better one.

If you are training consistently and eating carefully but not seeing the results you expect, nutrition is often the missing piece. I work with high-achieving adults 35 and over to build sustainable performance habits across nutrition, training, mindset, and recovery.
