Nutrition basics for staying strong over 45
I've watched more diets come and go than I can count. The grapefruit one, the shakes, the one where you weren't allowed to eat after six, the one where carbs were suddenly the enemy of all things. They arrive with a lot of noise, they work for about three weeks, and then real life turns up and they fall apart. If you're over 45 and tired of that cycle, this one's for you.
I'm Tracy Austin. As well as being a personal trainer, I'm a nutritional adviser, and I've spent twenty years helping people eat in a way they can actually keep going. I want to be clear up front: none of this is about being perfect, and none of it is medical advice. It's the simple, boring stuff that works.
Start with protein
If you take one thing from this, make it protein. As we get older our bodies get a little less efficient at using it, and at the same time we're trying hard to hold on to the muscle that keeps us strong and independent. Protein is what feeds that muscle.
You don't need powders or complicated maths. A palm-sized portion at each meal does the job — eggs at breakfast, some chicken or fish or beans at lunch, a proper serving in the evening. Spreading it through the day works better than piling it all into dinner. It also, as a happy side effect, keeps you fuller for longer, which quietly sorts out a lot of the snacking that creeps in through the afternoon.
Protein and training are two halves of the same job. There's little point building muscle in the gym if you're not giving your body what it needs to keep it, which is exactly why I pair this with strength training over 50 for every client at this stage of life.
Lean towards whole foods
Whole foods — things that look roughly like they did when they came out of the ground, off the tree or from the animal — do more for you per mouthful and tend to leave you satisfied. Vegetables, fruit, oats, potatoes, wholegrains, fish, eggs, dairy, beans, lentils, nuts. Fill most of your plate with those and you honestly don't need to fuss much about the rest.
This isn't about banning anything. I'm not going to tell you to never have a slice of cake at your grandson's birthday — that would be a miserable way to live, and you'd rightly ignore me. It's about what fills most of your plate, most of the time. Get that right and there's plenty of room for the treats.
The best diet is the one you're still following in a year. Everything else is just a story you tell yourself for a fortnight.
Drink more water than you think
It sounds almost too simple to mention, but so many people I work with are quietly running on empty. Mild dehydration shows up as tiredness, headaches, foggy thinking and, very often, as hunger that isn't really hunger at all. A glass of water with each meal and a bottle on the go through the day covers most people. Tea and coffee count too, within reason.
Why crash diets backfire
Here's the honest bit about the dramatic diets. When you cut too hard and too fast, your body doesn't just shed fat — it gives up muscle as well, and muscle is precisely what we're fighting to keep over 45. You end up hungry, flat, and unable to sustain it. Then normal eating returns, the weight comes back, and often it brings a friend. You've worked hard to end up worse off, and you feel like it's your fault. It isn't. The approach was wrong, not you.
Slow and steady genuinely wins here. A few small changes you can hold onto for years will always beat a heroic month that leaves you back where you started. This is the same thinking behind staying strong in later life — it's the long game that counts.
Simple habits that actually stick
- Protein at every meal. A palm-sized portion, three times a day.
- Two fists of vegetables at lunch and dinner. Colour on the plate rarely steers you wrong.
- Water first. Before you assume you're hungry, have a glass and wait ten minutes.
- Eat sitting down, without a screen, when you can. You notice when you're full far sooner.
- Don't ban foods. The forbidden ones are the ones you end up eating a whole packet of at ten o'clock.
Pick one. Get it steady for a couple of weeks. Then add another. That's how change lasts.
Nutrition and training go together
Good eating and good training are partners. One feeds the other. When a new client starts with me, we talk about both from day one — not because I'll ever hand you a rigid meal plan to follow to the gram, but because a few sensible habits alongside your sessions is what turns effort into results. You can see how I structure the coaching on the services page, and if the menopause is part of your picture, there's more on that in menopause and strength training.
Questions, answered
How much protein do I need over 45?
A good rule of thumb is a palm-sized portion of protein at each meal — eggs, fish, chicken, Greek yoghurt, beans or lentils. Our bodies use protein a little less efficiently as we age, so spreading it across the day, rather than saving it all for the evening, helps you hold on to muscle.
Are carbs bad once you're over 45?
No. Cutting out whole food groups is exactly the kind of thing that makes eating well feel impossible and short-lived. Carbohydrates fuel your training and your day. Lean towards whole versions — oats, potatoes, wholegrains, fruit — and you rarely need to worry about them beyond that.
Do I need to count calories to lose weight?
For most people, no. Building meals around protein and vegetables, drinking enough water and not eating on autopilot does the heavy lifting without a spreadsheet. Counting can be a useful short-term tool for some, but it isn't the point, and obsessing over numbers tends to backfire.
Why do crash diets stop working?
Crash diets cut so hard that you lose muscle along with fat, leave yourself hungry and tired, and can't keep it up. The weight comes back, often with a little extra, and you feel worse for the effort. Small, sustainable changes you can hold for years beat a dramatic month every single time.
As a personal trainer in Horley and nutritional adviser, I weave all of this into every programme — if you'd like a hand putting it into practice, come and have a chat.
If you'd like help getting the eating and the training working together — without fads, calorie-counting or being told off — the first 30-minute chat is free and there's no pressure at the end of it. Send me a message and I'll get back to you the same day.
