Did You Lose Weight on the Camino de Santiago?

I did not set out to lose weight on the Camino de Santiago. I set out to walk, to clear my head, and to escape the chair I had spent the previous decade slowly fusing with. The weight came off anyway. About eight kilos, roughly eighteen pounds, gone over four weeks, and I had a daily ice cream the whole way. I want to be honest about that up front, because most of what you read about weight loss on the Camino reads like a diet plan in a fleece. This is not that. This is a pilgrim telling you what happened to his body, and trying to work out, in retrospect, why.

Let me say the unglamorous thing first. I am not a fitness person. Before I left, a normal day involved roughly ten hours at a computer, a kettle within arm's reach, and the sort of evening routine where the fridge and the television seemed to operate as a single appliance. So the contrast was stark. I went from almost no movement to walking the better part of a marathon's distance most days, and the change in my current weight was the body simply reacting to that. No willpower involved. If anything, willpower would have ruined it.

How much weight do people lose walking the Camino de Santiago?

The honest answer is: it varies, wildly, and anyone who gives you a tidy figure is guessing. I have read forum threads where someone dropped 7kg in ten days and others where a person finished the whole Camino Francés having lost almost nothing, or even put a little on. Both are true. The range depends on where you start, how far you walk, what you carry, and how your appetite behaves when you ask your legs to do unfamiliar work.

What I can tell you is the shape of it for me and for the people I walked beside. The weight tended to come off slower at first, then more obviously in the second and third weeks, and then it would plateau as the body found a new balance. The early days felt like nothing was happening. By the meseta, the flat middle section, trousers were loose and a belt had migrated two notches.

To set rough expectations rather than promises, here is the spread I saw and heard about, framed honestly. Treat the figures as anecdote, not a study.

Walking pattern	Typical distance per day	What people often reported
Short route, last 100km	Around 20 to 25 km	Little change; not long enough for much to shift
Two to three weeks	Around 20 to 28 km	Noticeable loosening of clothes; a few kilos
Full Camino Francés, four to five weeks	Around 25 km	Several kilos; some people much more, some less
Carrying a heavy backpack daily	Variable	More effort burned, but higher injury risk

So if you are someone fairly overweight starting out, and you walk a long route consistently, the change can be significant. If you are already lean and you only have ten days, you may notice almost nothing on the scale and a great deal in your legs. The number is the least interesting part of the story, and I will get to why.

How much walking did I actually do, and how does that burn calories?

Most days on the Camino Francés I walked roughly 25 km. Some stages were shorter, a gentle 16km amble into Pamplona; others stretched longer and meaner, the kind that has you doing sums in your head about how far the next bar might be. On a good day the walking took five or six hours. On a hard one it took most of the daylight.

You do not need to obsess over the maths, but the principle is simple enough. Walking for five or six hours uses far more energy than sitting for ten. I will not throw a precise calorie figure at you, because the real number depends on your weight, the terrain, your pace, and how much your backpack weighs, and any single statistic would be a polite lie. What matters is the direction: more hours moving means a much higher daily expenditure, day after day, with no rest from it.

That last part is the quiet engine of it. At home, even an enthusiastic gym session is one hour against twenty-three of stillness. On the Camino, the movement is the day. There is no sitting it out. You burn more calories not because any single hour is intense, but because the whole rhythm of life has changed shape.

How do hills, pace, and carrying a backpack change the physical impact?

Three things turned the effort dial up or down for me, and they are worth understanding before you romanticise the whole thing.

• Hills. The climb out of Saint-Jean over the Pyrenees, and the long pull up to O Cebreiro in Galicia, asked far more of me than the flat meseta. More intensity, more sweat, more recovery needed afterwards. Routes with more slopes simply make you work harder.
• Pace. Steady beat sprinting every time. The pilgrims who tried to race burned out, hurt themselves, or both. A consistent rhythm you can repeat tomorrow does more, over a long distance, than one heroic day followed by a limp.
• Pack weight. Carrying my own backpack added effort, and that effort burned more, but it also added strain to knees and feet. Luggage transfer takes the load off and lowers injury risk, at the cost of some of the burn. Neither is wrong. Walking consistently is what counts.

If you want to dig into the carrying question properly, it is worth thinking hard about how to choose a backpack for the Camino de Santiago before you go, because the wrong load on your back will cost you more than a few extra calories burned.

I ate freely and had ice cream daily, so why did I still lose weight?

Here is the part people find hard to believe. I did not restrict anything. I had a café con leche and a tostada most mornings, the menú del peregrino most evenings, cheese and bread and whatever looked good in between, and an ice cream nearly every single afternoon. No diet. No counting. And the weight still went.

The simplest explanation is that the energy my body needed each day rose so much that the treats could not keep pace with the burn. When you are walking 25 km, an ice cream is not an indulgence the body has to fight against. It is fuel it quietly absorbs. A scoop of ice cream might be a couple of hundred calories. A day of walking is in a different league entirely.

But there is more to it than arithmetic, and this is where it gets interesting. The Camino reshapes how you eat without you deciding to. A few things happened to me without any intention behind them.

• My meals became structured. Breakfast, a mid-morning stop, dinner. Three honest meals, not the constant grazing of home.
• The always-stocked fridge vanished. In its place was an empty larder, or rather no larder at all, just whatever the next village sold.
• The snacking that was bolted onto television simply had nowhere to live. No sofa, no telly, no reflex reach for a packet.

That empty-larder effect surprised me most. At home I ate because food was there. On the Camino, food appeared at mealtimes and then the next opportunity might be ten kilometres down a dusty track. The environment did the work that no diet had ever managed. I was not resisting temptation. The temptation had quietly packed up and gone home.

What does a typical Camino day of eating look like?

People imagine pilgrim fare as either monastic or gluttonous. It is neither. It is ordinary, repetitive, and oddly satisfying. A rough day on a plate looked like this:

• Morning: café con leche and a tostada, sometimes a second coffee if the bar had a view worth lingering for.
• On the trail: a piece of fruit, some cheese, a hunk of bread, occasionally a slab of tortilla bought at a stop.
• Afternoon: the ice cream, non-negotiable, eaten on a kerb with my boots off.
• Evening: the menú del peregrino, three courses and wine for not much money, which I ate with the appetite of someone who had earned it.

What shifted was less what I ate and more when, and how my appetite behaved around long stages. Some days I was ravenous. Other days, oddly, after a very long walk I barely wanted dinner at all. Appetite on the Camino is not a straight line. If you want a fuller picture of the cuisine and the pilgrim menu tradition, there is a good account of what food is like on the Camino de Santiago worth reading before you go.

What non-exercise factors helped me lose weight without trying?

If I credited the walking alone, I would be telling you only half the truth. A surprising amount of the weight loss came from things that had nothing to do with calories burned and everything to do with the disruption of old habits.

At home, a good deal of my eating was not hunger at all. It was boredom, or the small stress of a stuck piece of work, answered by a trip to the kitchen. On the Camino those triggers vanished. Boredom became a reason to look at the landscape, not the fridge. Stress, when it came, was about blisters or finding a bed, and walking was already the answer to it. The movement replaced the snacking because the movement was the day.

There is a tidy way some people frame the maths of this, the so-called 3-3-3 idea you will see floating around: three meals, no snacks between them, and a gap of around three hours after eating before bed, repeated over roughly three days to settle into a rhythm. I would not call it a rule, and I would not put much faith in the precision of it. But it does describe, loosely, what the Camino imposed on me by accident. Structured meals, no grazing, and an early collapse into bed long after the last bite. I did not follow a method. The road handed me one.

A few other quiet contributors I noticed:

• Sleep changed. I went to bed when it got dark and woke with the zips and rustles of the albergue at dawn, which seemed to steady my hunger.
• Routine replaced choice. Fewer decisions about food meant fewer chances to eat for the sake of it.
• Walking with others set the rhythm. Shared meal times and a shared pace pulled me into healthier habits without a word being said.

What is the 3-3-3 rule for fat loss, and does it apply on the Camino?

Since people search for it, let me address the 3-3-3 idea directly rather than leave it dangling. You will find a few different versions online, which tells you something about how solid it is. The most common framing for fat loss is the meal pattern I described above. Another version, borrowed from exercise advice, talks about three sets of three exercises for three rounds, which has nothing to do with the Camino and need not detain us.

My honest view is that the appeal of any 3-3-3 rule is that it gives shape to something simple: eat at proper intervals, stop grazing, and move regularly. The Camino delivers all of that without a numbered rule. So if the framework helps you think about your eating, fine. If it makes you anxious about counting hours and sets, drop it. The pilgrimage does the heavy lifting on its own.

Does walking the Camino flatten your stomach or change your body shape?

People want to know if hiking flattens your stomach, and I understand the question even if the answer is a little disappointing. Walking does not target your belly. The body does not lose fat from one chosen spot because you asked it to. What happens instead is more general and, I think, more pleasing.

Over four weeks my whole shape changed rather than one part of it. My legs grew obvious muscle, the kind that makes stairs feel insulting when you get home. My face thinned. My clothes hung differently. The midsection did look flatter by the end, but that was a side effect of overall weight loss and a great deal of daily walking, not some magic of hiking acting on the stomach specifically.

And here is the contradiction I want to be honest about: I cared about this far less by the end than I expected to. I will come back to that, because it turned out to be one of the more important things the Camino did to me.

What are the other health benefits of walking the Camino de Santiago?

Weight loss was the visible result, but it was not the one I valued most by the time I reached the cathedral. The less measurable changes ran deeper.

My head cleared in a way no holiday had ever managed. There is something about the repetitive simplicity of putting one foot in front of the other for hours that quiets the noise. The wind seemed to snag at small anxieties and carry them off down the track. I slept better than I had in years. My mood lifted, not in a sudden burst but as a slow, accumulating thing, like the way a sky brightens before you notice the sun is properly up.

There were physical benefits beyond the scale too. My resting heart rate dropped. My legs and back, which had spent a decade complaining about that computer chair, stopped complaining. The act of walking long distance, day after day, seems to recalibrate a sedentary body in ways that feel almost suspicious for how simple the method is.

If the mental side is what draws you, you might find how walking the Camino de Santiago changed my life a more honest companion piece to this one, because the weight, in the end, was the smallest of the changes.

How important are diet and hydration for weight loss on the Camino?

I have made eating sound effortless, and mostly it was, but two things deserve proper attention: not under-fuelling, and staying hydrated. Both matter more than any clever diet.

The temptation, once you see weight coming off, is to lean into it and eat less. Resist that. Under-fuelling on a long walking day is how you end up dizzy, exhausted, and prone to injury. Your body needs real meals to walk 25 km and recover overnight to do it again. The pilgrims who tried to diet on top of the walking were the ones who flagged, struggled, and sometimes had to take unplanned rest days. Eat enough. The walking handles the rest.

Hydration is the other half. On a hot stage across the meseta you can lose a surprising amount through sweat, and a water bottle that runs dry by midday is a miserable thing. I carried water and drank regularly rather than waiting to feel thirsty. On the longest, hottest days I added a little electrolyte mix, and I kept a loose eye on the obvious signs of dehydration. Staying hydrated will not make you lose weight, but failing at it will make every kilometre harder and your recovery worse.

How can you tell the difference between fat loss and temporary water changes?

If you do find a set of scales on the Camino, which is rare, be sceptical of the daily number. Your weight swings from morning to night depending on hydration, heat, salt, and what is sitting in your gut. A long sweaty stage can show a dramatic drop that is mostly water, gone again after a good drink and a meal.

So I stopped trusting the scale and started trusting better signals. How my clothes fit. How much energy I had. Whether my legs felt strong on the climbs. Whether I recovered overnight. Those tell you about real change in a way a single morning weigh-in never will. My advice is to avoid daily weigh-ins entirely on the trail. Watch the belt, not the bathroom scale.

Do you need to be fit before you walk the Camino de Santiago?

No, but a little preparation makes the early days far kinder. I was not fit when I started, and I survived, though the first week taught me some sharp lessons about feet and pace. The Camino is forgiving in that it lets you build fitness as you go. You do not need to be an athlete. You need to be able to walk, rest, and walk again.

That said, doing some walking before you leave, ideally in the boots you will wear and with the pack you will carry, spares you the worst of the early misery. The point of training is not to maximise weight loss. It is to enjoy the walk rather than endure it, and to lower your risk of injury in the first hard days. If you want a sensible starting point, there is a practical guide to getting fit for the Camino de Santiago that will not turn the preparation into a chore.

Is weight loss on the Camino always healthy, and what should you watch for?

For most people, losing some weight while walking a long distance is a fine and natural thing. But rapid weight loss is not automatically good, and there are signs worth watching so it does not tip into a problem.

Pay attention if you notice any of these:

• Persistent fatigue that sleep does not fix, or feeling unrecovered each morning.
• Dizziness or light-headedness, which often means you are under-fuelled or under-hydrated.
• A loss of appetite so complete that you genuinely cannot eat enough to keep walking.
• Niggling injuries that appear when the body is running on empty: shin splints, knee pain, the slow misery of blisters.

The thread running through all of these is the same: do not treat the Camino as a crash diet with scenery. The weight loss is healthiest as a by-product of walking well, eating properly, and resting when you need to. Pushing harder and eating less is not a virtue out there. It is how people end up injured. A planned rest day is not a failure; it is maintenance, the kind of sense I wish I had shown before my legs forced the issue on me.

Should you use trekking poles, stretch, or train to protect yourself?

A few practical guards against turning effort into injury, none of them dramatic:

• Trekking poles take real load off the knees on descents and steady you on rough ground. I was sceptical, then converted somewhere on a steep Galician path.
• A light warm-up and some gentle stretching kept me mobile, especially in the cold morning starts. I make no grand promises for it, but it helped.
• Easing into the distances rather than charging at them lets the body adapt. The first few days at a gentler pace pay you back later.

Are some Camino routes better for weight loss than others?

In a narrow sense, yes. Hillier, longer routes ask more of the body, so they tend to burn more. The Camino del Norte, hugging the northern coast with its endless ups and downs, is harder underfoot than the gentler stretches of the Camino Francés. The Camino Primitivo is harder still. More climbing, more effort, more burn.

But I would not choose a route for its calorie burn, and here is why. The route you finish beats the route that defeats you. A hard route you abandon in week one does nothing for your body or your spirit. The best route for weight loss is the one you can walk consistently, day after day, at a pace you can repeat. Consistency is the real lever, not gradient. If you are weighing up the options, the question of how to choose the best Camino de Santiago route for you is worth more thought than which one promises the steepest hills.

Route	Terrain character	Note for the weight-curious
Camino Francés	Mixed; a long flat middle	Steady and walkable; good for consistency over weeks
Camino del Norte	Coastal, frequent ups and downs	More effort per day, but tougher to sustain
Camino Primitivo	Mountainous, demanding	High burn, high difficulty; not for a first long walk
Last 100km options	Variable, shorter	Too brief for much weight change, but a fine first taste

What the Camino did for my mind, and why I stopped caring about the scale

I promised to come back to this, so here it is, the thing I least expected. Somewhere around the second week, I noticed I had stopped caring what I looked like. Not in a defeated way. In a freed way.

At home I had spent years quietly negotiating with my own appearance, the mirror, the waistband, the low hum of dissatisfaction that a sedentary life feeds. On the trail that simply fell away. I was wearing the same two shirts on rotation. My hair did as it pleased. Everyone around me was sweaty, sunburnt, and limping slightly, and nobody minded a bit. The pressure to look a certain way had no oxygen out there.

And that, oddly, made the healthy behaviours easier. When you are not anxiously trying to lose weight, you eat when hungry, walk because you love it, and rest when tired. The body responds to that kindness better than it ever responds to pressure. What mattered shifted from how my body looked to what it could do: carry me 25 km, climb a mountain, recover, and do it again tomorrow. The weight loss was real, but it had become the least of it. I had set out to walk and lose a bit of stress. I had not expected to lose the habit of judging myself.

How to support a healthier change on the Camino without making it a diet

If you want the body changes without turning your pilgrimage into a joyless regime, the approach is gentle and unremarkable. It worked for me precisely because it asked for so little discipline.

• Choose stage lengths you can repeat without dread; consistency beats heroics every time.
• Eat real, sufficient meals, with enough protein to let your muscles recover overnight.
• Snack with a purpose, carrying something you will actually eat rather than a worthy item that stays in the pack.
• Stay hydrated through the day rather than gulping when you finally remember.
• Respect recovery: sleep properly, take a rest day before you need one, and walk a lighter stage when your body asks.

Above all, aim for completion and enjoyment. The physical changes follow the walking; they do not need to be chased. Chase the road instead, and let your body quietly sort itself out behind your back, which is more or less what mine did.

Frequently asked questions about weight loss on the Camino de Santiago

How much weight do people typically lose walking the Camino?

It ranges enormously and depends on distance, terrain, starting weight, food intake, pack weight, and how consistently you walk. On a full four to five week route some people lose several kilos, while a short walk of a few days often produces little change. My own result was about eight kilos over four weeks, but I would treat any single figure, including mine, as anecdote rather than a promise.

Can you lose weight on the Camino even if you eat dessert or drink wine?

Yes, many pilgrims do, and I am living proof, having had an ice cream nearly every afternoon. The sheer volume of daily walking can outweigh ordinary indulgences within reason. You are not trying to be perfect; you are trying to be well-fed enough to keep walking, and the burn from 25 km a day does the rest.

Will I gain the weight back after I return home?

Some regain is common when the activity drops away and old routines return. The fridge is full again, the television is back, and the 25 km a day stops. The habits you choose to keep, a regular walk, fewer mindless snacks, structured meals, make the biggest difference to whether the change lasts. The Camino can start something, but home decides if it sticks.

Is it safe to diet while walking the Camino?

Generally no. Deliberately under-eating on top of long daily walking tends to leave you fatigued, dizzy, and more prone to injury. Your body needs proper meals to walk a long distance and recover overnight. Aim to be steady and well-fed; let the walking, not restriction, do the work.

Does carrying a backpack instead of using luggage transfer help you lose more weight?

Carrying your own backpack does add effort, and that effort burns a little more, but it also raises the strain on your knees and feet and the risk of injury. The better question is which option lets you walk consistently and safely across the whole route. Whatever keeps you moving day after day will do more for your body than the marginal extra burn of a heavy pack.
