If you’ve ever experienced being overweight then you’ve probably heard this dreaded phrase.
“Eat less. Move more.”
On the surface, it makes sense. If you consume more calories than you burn, you’ll gain weight. Consume fewer than you burn, and you’ll lose it.
From a purely scientific standpoint, that’s true.
But after spending more than two decades helping people improve their health, I’ve learned that what causes someone to overeat or struggle to stay active is rarely simple.
If obesity were just about willpower, we wouldn’t be seeing record numbers of people struggling with their weight despite having more fad diets, fitness apps, calorie trackers and health information available than ever before.
The reality is that body weight is influenced by dozens of factors, many of which interact with each other. That doesn’t mean we have no control over our health. It means that before we can make meaningful, lasting changes, we need to understand what we’re really dealing with.
The calorie equation still matters…
Let’s address the elephant in the room first. Yes, weight gain ultimately happens because, over time, we consume more energy than our bodies use. There is no escaping that.
Sometimes people swing too far in the opposite direction and suggest that calories don’t matter at all. They absolutely do. However, saying obesity is “just calories” is a bit like saying debt is simply “spending more than you earn.”
It’s technically correct but practically simplistic.
The more interesting question is:
“Why are people consuming more calories than they need in the first place?“
That’s where things become far more complicated.
We no longer live in an environment that makes healthy choices easy
Imagine trying to save money while advertisements constantly encouraged you to buy, buy, buy.
Your phone reminds you that the thingy you just looked at half an hour ago is 25% off.
Shops place chocolately treats beside the checkout.
Friends regularly invited you to eat/drink out.
If everything around you encourages buying. Then saving would become much harder.
Food works in a similar way. We’re surrounded by highly processed, inexpensive, heavily marketed foods designed to be hyper-palatable.
They’re available almost everywhere from:
- Petrol stations.
- Train stations.
- Coffee shops.
- Supermarkets.
- Workplaces.
- Even commercial gyms.
Many foods are engineered to combine sugar, fat and salt in ways that make stopping after one portion amazingly difficult. Check out our blog on Ultra processed food to learn more.
Of course none of this removes personal responsibility, but it does explain why maintaining healthy habits requires more conscious effort than it once did.
Stress changes more than your mood
One of the biggest surprises for many new clients is how much stress affects their eating habits. Stress isn’t simply something that happens in your head. It changes what happens throughout your body.
When we’re under constant pressure, many of us become:
- hungrier
- less active
- more likely to crave highly palatable foods
- less likely to cook
- more likely to snack
- more likely to drink alcohol
- less motivated to exercise
After a difficult day at work, your brain isn’t asking for grilled chicken and steamed broccoli. It’s looking for comfort. That doesn’t make you weak. It makes you human. The challenge is recognising those patterns before they become habit.
Sleep may be the most underrated weight-loss tool
If I could persuade every client to improve just one habit before worrying about supplements or complicated diets, sleep would be near the top of the list.
When people are consistently short of sleep, several things often happen:
- They feel hungrier.
- They have less energy.
- They move less during the day.
- They crave quick sources of energy.
- Decision-making becomes harder.
- Exercise feels more difficult.
The result? Many people end up eating more without ever intending to. Think about the last time you were exhausted. Were you craving fresh vegetables? Or were biscuits, chocolate and takeaway food sounding much more appealing?
Most of us know the answer.
It’s difficult to train when life is overwhelming
I’m sure you’re tired of hearing,
“I just need more discipline.”
Maybe.
But sometimes they need more support instead.
Imagine someone who is:
- working full-time
- caring for elderly parents
- raising young children
- sleeping five hours a night
- worried about paying bills
- dealing with back pain
Now compare them with someone who:
- sleeps eight hours
- has flexible working hours
- can afford quality food
- has plenty of free time
- enjoys good physical health
Both people are capable of making healthy choices, but one has significantly more obstacles to overcome every single day. Acknowledging those differences isn’t making excuses.
It’s recognising reality.
Money influences health more than many people realise
Healthy eating doesn’t have to be expensive, but healthier living often comes with hidden costs.
Fresh food spoils more quickly. Some areas (like Glasgow) have convenience food one every street corner.
Gym memberships cost money. Sports equipment costs money.
Time spent cooking is time not spent earning. Some people work multiple jobs. Some rely on shift work. Others have unpredictable schedules that make planning meals almost impossible.
None of this means change is impossible. It simply means that advice needs to fit people’s real lives. Telling someone to prepare elaborate meals every evening isn’t helpful if they don’t get home until 9pm.
Habits quietly shape our future
One of the biggest lessons I’ve learned as a coach who has battled obesity in the past is this:
Most of what we do each day isn’t a conscious decision. It’s habit.
We eat lunch at certain times.
We buy coffee from the same café.
We snack while watching television.
We order takeaway every Friday.
We drive short distances instead of walking.
We sit in the same chair every evening.
Over months and years, these small habits become our normal. That’s why successful weight loss rarely comes from dramatic changes. It comes from gradually changing everyday routines.
Walking after dinner.
Cooking one extra meal at home.
Replacing sugary drinks with water or tea.
Strength training twice each week.
Sleeping an extra thirty minutes.
Small improvements repeated consistently produce remarkable results.
Genetics play a role, but you aren’t prisoner to them
We’ve all met families where several members are overwight. Genetics influence appetite. They influence how full we feel. They influence where we store body fat.
Some people naturally burn slightly more energy than others. Some feel hungrier after eating.
Yes, it’s unfair, but it’s also only part of the story. Your genes influence your starting point. They do not determine your destination.
I’ve worked with clients who believed they were “destined” to be overweight because everyone in their family was.
Many proved themselves wrong. Not because their genetics changed, but because their habits did.
Medication can influence body weight
Another topic receiving much more attention today is medication. Some medicines can increase appetite. Others affect metabolism or water retention.
Weight-loss medications like Wegovy and Mounjaro have also changed the conversation entirely. These medicines can help many people lose significant amounts of weight. That is a big positive, but edication still works best alongside healthier eating, regular movement and strength training.
At DMC Fitness we’ve spoken before about preserving muscle during weight loss in Weight Loss vs Fat Loss. Whether someone loses weight naturally or with medication, maintaining muscle is incredibly important for long-term health, mobility and keeping weight off.
Medication isn’t cheating. Exercise isn’t optional either. The two work together more effectively.
We also need to stop making exercise a punishment
One of the saddest things I hear is:
“I need to work that off in the gym.”
Exercise deserves better than that. Movement isn’t something you earn through good behaviour. It shouldn’t be seen as punishment for eating a tasty pizza.
Exercise should improve your life.
It should help you:
- sleep better
- move more easily
- reduce pain
- improve confidence
- become stronger
- manage stress
- stay independent
Ironically, people who exercise because they enjoy feeling healthier often stay active longer than those exercising purely to work off the over indulgence of the weekend.
Progress starts where you are, not where someone else is
One mistake social media encourages is comparing ourselves with people living completely different lives.
The retired couple with plenty of free time.
The fitness influencer whose job is staying in shape.
The twenty-year-old athlete.
Your plan should fit your life.
Not theirs.
If you’re currently inactive, don’t worry about running marathons. Start by walking.
If cooking every meal isn’t realistic, improve one meal each day.
If joining a gym feels intimidating, begin at home.
Progress doesn’t require perfection. It requires consistency.
The goal isn’t simply weight loss
One thing I often tell clients is this:
If all we achieve is making the scales move, we’ve failed. The real goal is helping people become healthier.
That might mean:
- lowering blood pressure
- improving blood sugar control
- reducing joint pain
- increasing energy
- sleeping better
- feeling more confident
- building strength
- playing with grandchildren without getting out of breath
Sometimes those improvements appear before significant weight loss. They’re just as worth celebrating.
So… is obesity just about eating too much and moving too little?
NO it isn’t Obesity is influenced by biology, psychology, environment, stress, sleep, income, habits, medications, relationships, work, food availability and countless daily decisions.
Understanding those influences isn’t about making excuses. It’s about making better solutions.
Once we understand why we’re struggling, we can begin changing the things that are within our control.
And that’s where real progress begins. At DMC Fitness we don’t believe in blaming people for where they are today. We believe in helping them take the next step.
Whether that’s improving mobility, building strength, losing weight, reducing pain or simply feeling healthier than they did last month, lasting change comes from realistic habits that fit real lives.
Your circumstances matter.
Your choices matter too.
The good news is that no matter where you’re starting from, you don’t have to change everything overnight. You Just have to start. We can help with that if you feel you need it. Just get in touch.
