Why We Keep Stopping and the Real Reason Your Weight Keeps Coming Back
Darren Tebbenham is a metabolic and mental health expert known for the idea that metabolic health is mental health. A former university lecturer in exercise psychology, he co-founded Gloo Fitness, authored two books, has trained more than 3,000 health professionals from 30+ countries & now speaks to organisations on energy, wellbeing & performance.
You have lost weight before. Probably more than once. The problem was never starting. It was what happened in week three, when life got in the way and the old pattern quietly took over again. This article explores why weight-loss efforts stall and how to build habits that better support your body and long-term goals.
The cycle on weight loss
Most of the women I work with are not short of discipline. They have built careers, raised families, run households and teams. They are the ones other people rely on. Organised, capable, they get things done.
Yet there is one area of life where the pattern looks completely different.
It goes like this. Something prompts a fresh start: a photo, a holiday, a dress that no longer fits. Monday arrives and you are all in. The first week goes well. The second week goes well enough. Then something gives. A stressful fortnight at work. A birthday. A weekend away. A few nights of bad sleep. One evening becomes a weekend, the weekend becomes “I’ll start again on Monday”, and a few months later you are back where you began. Sometimes a little heavier. Then you do it all again.
If that sounds familiar, I want to say something clearly before we go any further. This is not a willpower problem, and it is not a knowledge problem. Most people caught in this cycle could write the diet plan themselves. They have proved their willpower in every other part of their life.
In twenty-five years of coaching, I have come to think the cycle has two causes. One is in your head. The other is in your body. Most approaches only ever deal with one of them.
Reason 1: You keep stopping
Ask someone why their last attempt didn’t work and they will usually name the diet. Too strict. Too complicated. Too boring. So they look for a better one.
But the diet is rarely what failed. What failed was the stopping.
Every plan works if you stick to it. The trouble is that sticking to it runs into the same handful of moments every time: stress, overwhelm, social plans, the biscuit tin at work, the glass of wine at the end of a long day. Almost all of them hit hardest when you are tired. In those moments, an old and well-practised pattern takes over.
You probably know its voice. “I’ve blown it now, so I may as well enjoy the weekend.” “I deserve this, it’s been a horrible week.” “I’ll be good again from Monday.” These are not random thoughts. They are stories, rehearsed over years, and they make it feel perfectly reasonable to let this one area of your life slide when you would never accept that anywhere else.
This is why starting again doesn’t work. Each new attempt builds on the same foundation, so it collapses at the same weak point. The plan changes. The pattern underneath it doesn’t.
So the first job is not to find a better diet. It is to learn to stop stopping.
Reason 2: Your body has changed
The second reason surprises people more. Many of the women I coach are doing what they have been told is healthy eating, and it still isn’t working.
Porridge for breakfast. A smoothie mid-morning. Low-fat yoghurt, cereal bars, a sandwich at lunch. They feel like the good choices. But a lot of them are built around quick carbohydrates with little protein, and they tend to leave you hungry again within an hour or two. So you snack, or you white-knuckle it until the evening, when the hunger and the tiredness arrive together.
And over 40, the rules shift. We lose muscle as we age unless we work to keep it, and muscle matters for how well the body handles food and energy. For women, the hormonal changes of perimenopause and menopause can affect appetite, sleep, mood and where the body stores fat. What worked at 30 often stops working, even when you are doing it perfectly.
That is not a personal failing. It is biology. But it does mean that eating less and trying harder, the approach most of us default to, becomes less effective and harder to sustain at exactly the moment we lean on it most.
What tends to help is the opposite of punishment: proper meals, built around protein and real food, that keep you full and steady. Carbohydrates kept in check rather than cut out. No fear of fat. The right kind of exercise, especially strength work, that fits your body and your week.
A note on health: if you are dealing with persistent fatigue, unexplained weight change or significant symptoms of menopause, speak to your GP first. Thyroid problems, anaemia and other common conditions can all play a part, and they deserve proper attention.
Pattern first, then the plate
Most programmes start with your plate. That is why most programmes don’t last. Fix the food without the pattern, and you are back where you started within weeks. Fix the pattern without the food, and you stay stuck on a plan your body no longer responds to.
So in my coaching, the order matters. I call it working from the inside out.
The first few weeks are about the head. Getting honest about what has really stopped you before. Spotting the stories you tell yourself in the moments that matter. Getting clear on why this matters to you, and who you are becoming. Only then do we turn to the plate and the body, because by that point you have something solid to build on.
The biggest skill in all of this is not perfection. It is bouncing back fast. You will have a bad day. Everyone does. The difference is that one bad meal stays one bad meal, instead of becoming a lost month.
Maria came to us wanting to lose weight. That was it. She lost six and a half stone, then kept going, losing nine stone in just over two years. But ask her what changed and the weight is not the first thing she mentions. In her words: “I swapped the weight for confidence.”
She didn’t find a magic diet. She fixed the pattern first, then the plate. That is why it stuck.
Across our last hundred clients, online and in the studio, the total is more than 125 stone. Plenty of programmes can take weight off for a while. The part I care about is that, wherever we can keep tracking, it stays off. Individual results vary, of course. But the principle holds: done properly, it is done once.
3 things you can start this week
You don’t need a new plan to begin. You need to see the old pattern clearly. Three places to start:
Catch the story. The next time you feel the pull to give up for the day, notice the sentence in your head. Write it down, word for word. “I’ve blown it now” loses a lot of its power once you can see it on paper.
Fix breakfast first. Swap a carb-heavy breakfast for one built around protein: eggs, Greek yoghurt, leftovers from last night. Notice how you feel at 11 am and again at 4 pm. It is the simplest test I know of whether your plate is working for you or against you.
Plan the bounce back, not the perfect week. Decide now what you will do after a bad day. One normal meal. One walk. One early night. The goal is not to never slip. It is to make the slip short.
Start with the pattern
If you have handled everything else life has asked of you, it is worth asking why this one thing keeps beating you. The answer is almost never that you lack discipline. It is that you have been fixing the wrong thing first, on a body whose rules have quietly changed.
Deal with why you keep stopping, and give your body what it actually needs now, and something shifts. You stop starting again. You feel back in control, for good.
This time, don’t start with another diet. Start with the pattern.

Darren Tebbenham is a leader in metabolic and mental health, behaviour change, and human performance. A former university lecturer in sport and exercise psychology, he grew frustrated that knowing what to do rarely helped people actually do it, so he left the lecture hall to build methods that change behaviour from the inside out. He has since dedicated his career to helping people and organisations transform their health, energy and performance, having trained over 3,000 professionals across 30+ countries and co-founded Gloo Fitness. His mission is simple: metabolic health is mental health. Body and mind are inextricably linked, and both perform at their best only when we treat them as one.
