The Bottom Line: If you can’t lose weight despite eating what you’ve been told is healthy, the problem is not your effort or your discipline. It’s the food itself. Oats, bread, pasta, rice, and fruit spike insulin – the hormone that drives fat storage. Until you address that, no amount of exercise or calorie reduction will fix the problem. I know this because I ate those foods for 48 years and trained like a competitive athlete while getting heavier. The fix was not eating less. It was eating differently.
For 48 years, I ate what I was told was healthy. Oats. Bread. Pasta. Rice. Fruit. I trained consistently – marathons, triathlons, endurance events. I hired a dietitian. I followed the plan. I was doing everything right.
I was also gaining weight, constantly hungry, and getting heavier every year.
If that pattern sounds familiar, keep reading. Because the problem is not you. It’s the model you’ve been given.
Why do “healthy” carbs cause weight gain in men over 40?
The foods the nutrition establishment calls healthy – whole grains, fruit, low-fat products, complex carbohydrates – all have one thing in common: they raise insulin.
Insulin is not a villain. It’s a hormone doing its job. When you eat carbohydrates, your blood sugar rises, insulin is secreted to bring it back down, and nutrients are transported into cells for storage or use.
The problem is chronic overstimulation.
When insulin is elevated consistently – because you’re eating bread at breakfast, a sandwich at lunch, pasta at dinner, and fruit in between – your liver and muscle cells gradually stop responding to the signal. They become insulin resistant. Nutrients that should go into muscle and liver for energy storage end up in fat cells instead.
This is why you can exercise hard, eat “clean,” and still gain weight. The problem is hormonal, not mathematical. Counting calories does not change the underlying mechanism. It just makes you hungry while the same process continues.
There is a second mechanism worth understanding: the appestat.
The appestat is your body’s hunger-regulating system. When it’s functioning correctly, you eat, you feel satisfied, and you stay satisfied between meals. When processed carbohydrates and refined grains dominate your diet, the appestat gets disrupted. Hunger signals arrive persistently, even when your body has more than enough stored energy. You eat more, hunger comes back faster, and the cycle compounds.
Being constantly hungry while gaining weight is not a character flaw. It’s the appestat failing – driven directly by the foods you were told to eat more of.
How did I eat “healthy” for 48 years and still get this wrong?
I wasn’t eating junk. I was eating what every credible authority – sports dietitians, running coaches, the Australian Institute of Sport, the mainstream nutrition guidelines – told endurance athletes to eat.
Carbohydrates were the fuel. Pasta dinners before long runs. Gels during races. Oats every morning. On overseas business trips I’d grab pastries from hotel buffets to “keep my energy up” through long days. These weren’t bad choices by the model I was operating under. They were textbook correct.
But I was gaining weight despite training seriously. I was always hungry. And I was increasingly relying on regular carbohydrate hits just to maintain energy through the day.
That dependency felt normal because everyone around me had it too. It didn’t occur to me that the food was the problem – because the food had been positioned as the solution.
What changed my position on carbohydrates
I’d already been questioning the model when I came across Professor Tim Noakes – the man who wrote The Lore of Running, the bible of endurance nutrition.
Noakes had spent decades telling athletes to carb-load. Then he developed type 2 diabetes. He reviewed the research with fresh eyes and reversed his position entirely.
His instruction to athletes: tear out the section on nutrition from The Lore of Running.
That kind of intellectual honesty is rare. And it landed hard.
It confirmed what I was already suspecting: the advice I’d been following wasn’t just imperfect. It was driving the exact problem I was trying to fix. I stopped thinking of my carbohydrate eating as a necessary part of performance. I started thinking of it as a dependency – one I’d built up over four decades and one that was keeping me stuck.
I made the break. No partial measures, no transitional compromises. A clean exit from grains, processed carbohydrates, and the foods I’d built a forty-eight-year relationship with.
I drew on the research of Dr. Stephen Phinney and Dr. Jeff Volek on fat adaptation for endurance athletes, and Grant Schofield’s work on low-carb metabolic health. The science supported what I was experiencing.
What happened when I stopped eating “healthy” carbohydrates
The results across my own metrics:
- 2011, pre-change: 42.2km marathon at approximately 80kg, fuelled by carbohydrate drinks, not exactly brimming with energy
- December 2016, five years post-change: Completed a 70.3 Ironman in 5:03, racing at 64kg, with a marathon split 15 minutes faster than 2011 – without gels, without sports drinks, without grains
- End of 2017: Ranked 10th in the 50-54 age group for Australia in the Ironman All World Athlete rankings (70.3), top 5% of the age group
- 2025: 5km parkrun in 22:30, 2.4km run test in 9:40
The persistent hunger went away within weeks. The energy became stable across the day – no spikes, no crashes, no afternoon slumps requiring coffee or food to get through. My brain did not shut down without carbohydrates. It worked better.
I’ve since coached more than 850 men over 40 through the same shift. The pattern is consistent: men who have been eating “healthy” for years and can’t shift weight, who are always hungry, who are gaining despite training – they improve when the carbohydrates come out and the hormonal environment changes.
A few results from that group:
Martin, an engineer in his 50s: Three months of gym training plus calorie counting before working with me – lost 3kg. Twelve weeks on the approach I use: 12kg. His assessment: “I’ve probably added at least a decade to my life.”
Clint: Arrived as a type 2 diabetic on Metformin. In twelve weeks, his HbA1c dropped from 6.5 to 5.9 – clinical remission. He came off the cholesterol and triglyceride medication he’d been on for ten years. No drugs. The food did it.
Craig, a retired army officer: Started at 105kg. Four months later: 90kg. Blood markers improved across all categories. His comment: “It was almost embarrassingly easy.”
Why isn’t this the standard advice?
Because the food industry, the supplement companies, the sports drink manufacturers, and the major nutrition bodies have spent forty years and extraordinary sums of money building a framework that keeps grains at the centre of the human diet.
Carbohydrates are cheap to produce, easy to store, and highly profitable to sell in packaged forms. The “heart healthy whole grain” positioning was a marketing decision, not a nutritional one. The low-fat movement that emerged in the 1970s and 1980s demonised fat – the actual preferred fuel source of the human body – and replaced it with sugar and refined carbohydrates.
The result: four decades of rising obesity, metabolic disease, and type 2 diabetes in populations following those guidelines.
This is not a fringe position. Tim Noakes, Jason Fung, Stephen Phinney, Gary Taubes, and Phil Maffetone have all published extensively on the mechanisms behind it. The research base is substantial. The institutional resistance to changing the guidelines, however, is equally substantial – because the financial stakes of admitting the advice was wrong are enormous.
Conventional stupidity is not always ignorance. Sometimes it’s the business model.
What does cutting carbohydrates actually involve?
The first thing men ask: do I have to give up everything?
No. You give up the things that are disrupting your insulin and your appestat. Primarily: grains (including whole grains), processed foods, sugars, and the low-fat products engineered to replace fat with sugar and additives.
What stays: meat, fish, eggs, vegetables, full-fat dairy (if you tolerate it), nuts, healthy fats – butter, olive oil, coconut oil, animal fats, avocado. Real food, prepared simply.
The practical experience of men who make this shift is not deprivation. It’s the opposite. Hunger disappears. Cravings reduce significantly within the first two to three weeks. Meals become simpler. Food preparation becomes easier. The obsessive relationship with food – the constant thinking about when the next meal is, the hunger between meals, the energy crashes – fades.
That dependency is not a feature of healthy eating. It’s a feature of a diet that keeps you on the carbohydrate treadmill.
The principle is simple: nutrition drives weight loss. If you have to exercise to regulate your weight, your diet is wrong.
If what I’ve described sounds like your situation
The hunger that doesn’t stop. The weight that won’t shift despite doing what you were told. The training that feels like it should be working but isn’t. The blood markers heading in the wrong direction.
These are not signs of a discipline problem. They are signs of a model problem.
If you want to understand whether this approach is right for your situation, the next step is a conversation. It costs nothing and takes 30 minutes. I work with men who are ready to make the change – not men who want to be convinced that the change is worth making.

Frequently Asked Questions
Q: Why can’t I lose weight if I’m eating healthy foods like oats, fruit, and whole grains?
A: Because those foods raise insulin – the hormone that controls fat storage. When insulin is chronically elevated, your body stays in fat-storage mode regardless of how little you eat or how much you train. The fix is not eating less of those foods. It’s eating foods that don’t spike insulin: meat, fish, eggs, vegetables, and healthy fats.
Q: Do you need carbohydrates to exercise or train effectively?
A: No. The idea that carbohydrates are essential for performance comes from the sports nutrition industry and was never well-supported by the underlying physiology. Once your body adapts to using fat as its primary fuel source – a process called fat adaptation – it can sustain endurance performance without relying on glucose. I completed 70.3 Ironman events in the top 5% of my age group without gels or sports drinks after making this shift.
Q: Why am I always hungry even when I eat enough?
A: Persistent hunger on a “healthy” diet is a sign of a disrupted appestat – your body’s hunger-regulating mechanism. Processed carbohydrates and grains disrupt the appestat, causing hunger signals to fire even when your body has sufficient stored energy. When you switch to real food and reduce the foods that spike insulin, the appestat resets. The hunger goes away – not through discipline, but through removing the cause.
Q: Is cutting carbs just another fad diet?
A: Low-carbohydrate eating is not a fad. It predates the modern nutrition guidelines by centuries. The shift toward high-carbohydrate diets as the basis of “healthy” eating happened in the 1970s and 1980s – driven by the food industry’s financial interest in selling cheap, shelf-stable grain products, not by nutritional science. The research base supporting low-carb approaches for metabolic health, weight loss, and type 2 diabetes reversal is now substantial and growing.
Q: What do men over 40 actually need to eat to lose weight without counting calories?
A: Real food, primarily protein and healthy fats, with carbohydrates coming from vegetables rather than grains and processed products. Meat, fish, eggs, full-fat dairy, vegetables, nuts, and fats like butter, olive oil, and avocado. No calorie counting required. When insulin is managed through food choice, the body naturally regulates its weight.
Q: How long does it take to adapt to a low-carb diet?
A: Most men notice significant changes in hunger and energy within two to three weeks. Full fat adaptation – where the body is efficiently using stored fat as its primary fuel source – typically takes six to twelve weeks. After that, hunger becomes manageable and energy becomes stable across the day.
