Yes, and it’s the exercise I start nearly every man on. It also won’t take the weight off on its own. The trials that have measured it put the number at about two kilos, which is real, and nowhere near what you came here for.
Only about 10% of the men I work with do any gym work while they’re losing weight. The rest of them walk. And 95% of them lose between 15 and 40 kilos.
That doesn’t prove the walking took it off, because they changed what they ate too. That’s the point. What it proves is you don’t need a gym to lose 30 kilos.
The Bottom Line: Walking helps, but on its own it’ll help you lose about 2 kilos, coming off at roughly a kilo every five months, which is nowhere near enough when you’re carrying 20 or 30 extra kilos. What you eat moves the rest; walking’s real job is being the one thing a man that size can do every day for a year without his knees or his patience giving out. On the step target, ignore 10,000: the evidence sits at 7,000, and I ask my own clients for 15,000 while they’re losing weight. Don’t let a good step count convince you the diet is handled.
How much weight does walking help men over 40 lose?
About 2 kilos. A 2017 review pooled 22 randomised trials of brisk walking in adults with obesity: mean weight loss 2.13 kg, waist down 2.83 cm, fat mass down 2.59 kg. Fat-free mass went up slightly, which is why the scale moves less than the tape does, and the tape is the part that tracks visceral fat. The authors were explicit that the evidence for men over 50 is thin, so treat these as adult averages, not a number calibrated to you.
Two kilos isn’t nothing. If you’re five kilos over and holding, you don’t need me, and I’d tell you that on a call.
That’s not why you’re here though. You’re twenty or thirty kilos over, you’ve been over for years, and the number hasn’t moved in months despite the steps. At that scale walking alone is a rounding error, and every month you wait for it to work is another month the tape doesn’t move.
I learned this the expensive way. I was running 70 kilometres a week. My calves were killing me, I couldn’t walk properly, and I got down to 72 or 75 kilos. I was still fat. Not unfit. Fat. What finally changed my body was taking the bread, rice and pasta out. Six months later I was 65 kilos and it had come off easily. If you have to exercise to regulate your weight, your diet is wrong. I’ve explained why the food is the lever and the training is the finish in why the kitchen is your gym.
Anthony had the same problem from the other direction. He was exercising regularly and hadn’t moved in years. Twenty weeks after he fixed the plate he was 15 kilos down, and the aches he’d carried for years eased off as a side effect he hadn’t expected. Nobody had told him the exercise wasn’t the missing part.
Why is walking the exercise I start men over 40 on?
Because it’s the movement a man carrying 30 kilos can actually repeat every day for a year without breaking down, and that has nothing to do with what it burns. Strength work matters and it comes later, once the weight is moving and the food is handled. Start there instead and you tend not to get to later.
A client texted me from a gym floor before we’d even started. His trainer had pushed him so hard he’d had to stop and go and throw up. First thing I told him was we’re cutting that back and you’re going for walks. That isn’t me going soft. A man that size training at that intensity is loading knees and a back with no base under them. Then comes the injury, and three months he didn’t have. And for a lot of men a hard session ends with them eating more, not less, which is the one thing you can’t afford while you’re changing how you eat.
Walking asks almost nothing back. Next to no recovery, and you can do it in work shoes. How much a hard session drives appetite varies from one man to the next, which is exactly why I won’t gamble his first twelve weeks on it.
There’s a compensation problem underneath all this as well. Burn more in training and your body quietly spends less at rest to cover it. Which makes exercise the least reliable lever in the box, for the men who get told to pull it hardest. I’ve set that research out in full in is starvation mode real. Training does improve insulin sensitivity, and that’s worth having. It just doesn’t change what’s on the plate, and the plate is what sets the insulin load. If you want the aerobic side built without training yourself into the ground, that’s what MAF training is for.
Is 10,000 steps the right target for men over 40?
No. The evidence supports about 7,000 steps a day. The 10,000 figure came from a product name, not a laboratory: in 1965 a Japanese company launched a pedometer called the manpo-kei, which translates as the 10,000-step meter. Sixty years on, men are still treating it as a clinical threshold. The Harvard researchers who tested it put it plainly in print, saying the figure is commonly believed necessary for health and has limited scientific basis.
A 2025 University of Sydney review of 57 studies found 7,000 steps a day, against 2,000, associated with 47% lower all-cause mortality, 25% lower cardiovascular disease and 14% lower risk of type 2 diabetes, the curve flattening around 5,000 to 7,000. A 2022 meta-analysis of 15 cohorts and 47,471 adults put the plateau at 8,000 to 10,000 steps under 60, and 6,000 to 8,000 over 60.
Look at what those studies measured, though. Death, heart disease, diabetes, dementia. Not fat loss. They’re observational too, so they tell you higher step counts go with better odds, not that the steps did it. Those odds are worth far more than two kilos. Selling them to you as a weight loss protocol is still dishonest.
I ask my clients for 15,000 while they’re losing weight, well above any of those thresholds. That’s a coaching decision, not a research finding, and I’ll say so. Seven thousand fits inside the day you already have. Fifteen thousand doesn’t, and that’s the point of asking: it forces a standing desk, a walk after dinner and an early start into a day that has none of them.
What walking can and can’t do for a man with 20 kilos to lose
Walking is worth about two kilos on the scale, and the step research links it to far more than that on your odds of dying early. What you eat moves the other twenty. So walk, take the health benefits, and don’t let the step count become the thing you point at when the weight hasn’t moved in six months.
If you’re already walking every day and the belly is still there, you’ve got your answer. It’s on the plate, and you can’t see it, because you’ve been looking at it every day for twenty years.
Start tonight. Write down everything you eat and drink for seven days, exactly as it happened, including the parts you’d rather leave off. Then read it back honestly. That week shows you what’s going in. It won’t tell you which part is holding the weight on, what to put in its place, or how to still be doing it in six weeks.
One of my clients was a triathlete whose back injury had stopped his training completely. He’d spent years offsetting what he ate with three-hour rides and had stalled at 86 kilos. He’d tried the food change on his own more than once and quit every time around day ten. With someone on his shoulder he went from 89.9 to 83.5 in eight weeks, about a kilo a week, with no training at all. The riding was never what moved the weight, and neither was knowing what to do.
You don’t have to wait out the week to have the other conversation. On the call I’ll tell you what’s realistic for a man carrying what you’re carrying and what it would take to get there: how the coaching works, what you’d be committing to, and what it costs. Fair warning, I only work with men who have at least 10 kilos to go, because under that there isn’t enough to work with. If that’s you, start the diary tonight and book a session here while you’re at it.
Frequently Asked Questions
Is walking enough to lose weight for men over 40?
Not on its own, if you have a meaningful amount to lose. Pooled across 22 trials, brisk walking programs delivered around 2 kilos and just under 3 centimetres off the waist. That’s a genuine result and a very small one against 20 or 30 kilos. Walking is the movement that holds a plan together while the change in what you eat does the actual work.
How many steps a day should a man over 40 walk to lose weight?
About 7,000 steps a day is where the evidence sits, and that’s where the risk curves for mortality, heart disease and diabetes start to flatten. No step count produces weight loss on its own, though, so take the steps for the health benefit and fix the food separately. I ask my own clients for 15,000 while they’re losing weight, because a man who sits at a desk needs a target big enough to force a standing desk and a walk after dinner into his day.
Is walking or the gym better for losing weight after 40?
Walking, for most men, while the weight is coming off. Only about 10% of my clients do any gym work during that phase. A man carrying 30 kilos who goes hard in a gym is loading knees and a back with no base under them, and a lot of them come home and eat the whole session back. Lifting has its place and I’ll push men towards it, but it earns its slot once the weight is already coming off.
Why am I walking 10,000 steps a day and not losing weight?
Because steps were never the lever. The 10,000 figure was the trade name of a 1965 Japanese pedometer rather than a finding from any study, and across 22 trials of brisk walking programs the weight that came off was about 2 kilos. If you’re hitting your steps and the weight hasn’t shifted, the answer is almost always in what you’re eating: the bread, rice, pasta, cereal and anything sugary you drink. Change that for four weeks and watch the tape, not the scale.
