2 / Where to Start When Your Weight and Metabolism Feel Stuck

You understand now that your metabolism hasn’t simply “slowed down.” So what should you actually do about it? Surprisingly, probably less than you think.

If you read the first article in this series, you now know that midlife weight gain isn’t simply a story about eating too much. Ageing, declining estrogen, changes in body composition, loss of muscle, increasing visceral fat, insulin sensitivity, sleep and activity can all become part of the picture.

Which leaves us with the question I hear all the time:

“Fine. But where do I start?”

This is where I want to save you from making one of the most common mistakes I see in women over 45: trying to fix everything at once.

Suddenly there is no sugar, no bread, no alcohol, no eating after 6pm, fasting until noon, 10,000 steps every day, five workouts a week and a kitchen cupboard containing enough supplements to open a small pharmacy.

It usually lasts about twelve days.

Then real life returns.

If we are trying to improve metabolic health, I would much rather identify the few things that have the greatest effect and do them consistently. We are not going to start by eating less. We are going to start by making your body better at using what you eat.

And the first place I would start might surprise you.

Step one: protect your muscle before you worry about making yourself smaller

If I could change one thing about the way women have been taught to approach weight loss, it would be our obsession with burning calories.

For decades, women were encouraged to make themselves smaller. Eat less. Choose the lowest-calorie option. Do more cardio. Watch the number on the scales.

Very little was said about protecting the tissue we desperately need as we get older: muscle.

As we discussed in the first article, skeletal muscle is not simply something that makes your arms and legs look toned. It is metabolically active tissue and an important site of insulin-stimulated glucose uptake.

This means that when you eat and glucose enters your bloodstream, your muscles are one of the major places that can take up and use that glucose.

That changes the way I want you to think about exercise.

You are not exercising simply to “burn off dinner.”

You are building metabolic capacity.

Resistance training becomes particularly important with age because we are simultaneously trying to defend ourselves against age-related losses in muscle mass, strength and function.

And no, it is not too late.

A large 2026 systematic review and meta-analysis involving more than 4,000 women found that resistance training improved strength in both premenopausal and postmenopausal women. It also increased functional mass and reduced fat mass, with no meaningful evidence that older women were somehow unable to respond to training.

That is an incredibly important message.

Your muscles still adapt.

So if you currently do no resistance exercise, I wouldn’t begin by asking you to train six days a week. I would rather see you start with two or three properly structured resistance sessions each week, appropriate to your fitness, health and experience, and progressively challenge the muscles over time.

The goal isn’t exhaustion. It is adaptation.

And if you’ve never lifted weights before, getting some professional guidance at the beginning is an excellent investment.

Step two: stop treating protein as the garnish

Once we decide that preserving muscle matters, nutrition has to support that goal.

And this is where I often see a disconnect.

A woman tells me she wants to improve her metabolism and preserve muscle, and then describes breakfast as coffee and perhaps a piece of toast. Lunch is a salad. By dinner she is ravenous, and this is the meal where most of the day’s protein finally appears.

Protein gives us amino acids needed to maintain and repair body tissues, including muscle. Protein also tends to be more satiating than carbohydrate or fat, which can make adequate protein particularly useful when we’re trying to improve body composition without simply imposing increasingly severe calorie restriction.

I don’t want you obsessively counting every gram you eat for the rest of your life. But I do want you to have an idea of whether you are getting enough.

For many healthy midlife and older women, particularly those exercising and trying to maintain lean mass, protein requirements may be higher than the basic adult minimum. The exact amount should be individualised according to body size, diet, activity, age and medical circumstances.

And importantly, spread it across your day rather than saving almost all of it for dinner.

Think eggs, Greek yoghurt or skyr, fish, chicken, lean meat, cottage cheese, tofu, tempeh, beans, lentils or other foods that suit the way you eat.

The point is not to create another food rule. It is to look at your plate and ask a better question:

“Where is the protein?”

If you have kidney disease or another condition requiring dietary protein management, your intake needs to be discussed with your healthcare professional rather than following generic high-protein advice.

Step three: build meals that help your body manage glucose

Next, I want to move away from the idea of “good foods” and “bad foods.”

You do not automatically need a ketogenic diet because you are over 45. You do not need to eliminate fruit because it contains sugar. And a potato did not single-handedly create your menopause belly.

What matters much more is the overall metabolic quality of the diet.

A very simple place to begin is to build most meals around protein, plenty of vegetables or other fibre-rich plant foods, an appropriate portion of minimally processed carbohydrate and healthy fats.

Why fibre? Because fibre changes how food behaves inside your digestive system. Fibre-rich foods tend to slow digestion and glucose absorption, support bowel function and feed parts of the gut microbiota. Diets rich in whole plant foods are also consistently associated with better cardiometabolic health.

Why minimise ultra-processed food? Not because you need to become the woman who brings her own chia seeds to dinner.

Because many ultra-processed foods make it extraordinarily easy to consume a large amount of energy quickly while providing relatively little protein, fibre or satiety.

So instead of asking, “Can I eat carbohydrates?”, ask:

What carbohydrate am I eating, what am I eating it with, how much do I need, and what does the rest of my diet look like?

Those are far more useful metabolic questions.

Step four: use one of the simplest glucose tools we have

There is something wonderfully unsexy that I recommend all the time.

Walk after you eat.

You don’t need a supplement, an app or a glucose monitor to do it.

When muscles contract during activity, they increase their uptake of glucose. That means some of the glucose entering the bloodstream after a meal can be used by working muscle.

Research comparing exercise before and after eating has found that post-meal activity can produce a greater reduction in postprandial glucose excursions than exercising before the meal or remaining inactive. Walking relatively soon after eating appears particularly useful.

Even breaking up long periods of sitting with short bouts of activity can improve post-meal glucose and insulin responses.

So instead of thinking that movement only counts when you are wearing Lycra and your watch has officially declared it a workout, start using movement throughout your day.

Take a short walk after dinner. Walk after lunch when you can. Get up from your desk regularly. Take the stairs. Carry your shopping. Garden. Move.

Exercise is important. But so is not spending the other 15 waking hours sitting down.

Step five: stop pretending sleep has nothing to do with metabolism

This is the one people often want to skip.

Food? Fine.

Exercise? Fine.

Sleep? “Yes, yes, I know I should sleep more.”

But sleep isn’t simply recovery time. It is part of metabolic regulation.

In a randomized crossover trial in women, reducing habitual sleep by about 1.5 hours per night for six weeks impaired insulin sensitivity. Importantly, the effect occurred independently of changes in body fat.

That should make us pay attention.

And midlife women have plenty working against good sleep: night sweats, changing hormones, stress, alcohol, caring responsibilities, late-night screens, anxiety and sometimes sleep disorders such as obstructive sleep apnoea.

If you consistently sleep five or six hours, wake repeatedly through the night and spend the next day exhausted, I don’t want to treat sleep as a minor lifestyle detail while we obsess over whether you should eat half a banana.

The big things come first.

What about fasting?

This deserves mentioning because intermittent fasting has become almost synonymous with midlife weight loss.

Time-restricted eating can be a useful tool for some women. It can simplify eating, reduce late-night snacking and help some people reduce overall energy intake.

But fasting is a tool.

It isn’t a metabolic requirement.

If skipping breakfast means you feel fantastic, eat adequately later and maintain your protein and nutritional needs, that is one situation.

If it means coffee until midday, very little food all afternoon, ravenous hunger at 6pm and grazing until bedtime, I am considerably less impressed by your 16-hour fasting window.

I care much more about what the strategy is actually doing to your diet, muscle, appetite, energy and metabolic health than whether your fasting app gives you a gold star.

We will look at fasting, carbohydrate timing and more targeted metabolic strategies in the next article.

For now, you don’t need them.

And please don’t try to do all of this on Monday

This may be the most important part of this article.

You now have several things you could change. That does not mean you should change all of them tomorrow.

Start by looking honestly at your current life.

If you are not strength training, that might be your first project. If your meals contain very little protein, start there. If you already exercise but sit for ten hours a day, add movement throughout the day and after meals. If your sleep is terrible, don’t keep pretending that the solution is another diet.

Then build.

One habit becomes normal before another is layered on top.

Because the best metabolic programme isn’t the most impressive programme you can survive for three weeks.

It is the one that gradually becomes the way you live.

What I would NOT do first

I wouldn’t begin with a severe calorie deficit.

I wouldn’t eliminate carbohydrates without a clinical reason.

I wouldn’t start taking ten supplements for “metabolism.”

I wouldn’t buy a continuous glucose monitor simply because Instagram convinced you every glucose rise is dangerous.

I wouldn’t fast longer and longer because somebody told you that 18 hours is somehow metabolically superior to 14.

And I certainly wouldn’t judge whether the programme is working entirely by what happened on the scales this morning.

We are trying to improve metabolic health and body composition, not win a 14-day weight-loss competition.

What should you actually watch?

Yes, body weight can be useful if weight loss is one of your goals. But zoom out.

Measure your waist periodically. Notice whether your clothes fit differently. Track strength in the gym. Notice your energy. Pay attention to hunger and cravings. Look at your sleep. Monitor blood pressure if appropriate.

And over time, look at what is happening to your metabolic markers.

Because remember what we established in Article 1: a smaller body is not automatically a metabolically healthier body.

Which biomarkers I recommend checking for weight and metabolism

You do not need blood tests before you are allowed to start walking, eating better or lifting weights. But if you have significant abdominal weight gain, a strong family history of diabetes or cardiovascular disease, high blood pressure, previous gestational diabetes, symptoms suggesting thyroid dysfunction, or weight that has changed substantially without an obvious explanation, I would want to understand your baseline metabolic picture.

Useful tests to discuss with your doctor can include fasting glucose, HbA1c and, where appropriate, fasting insulin; a lipid panel including triglycerides, HDL-C, LDL-C and non-HDL cholesterol, with ApoB providing additional information about atherogenic particle burden; and ALT, AST and GGT to help assess liver health.

Depending on your history and symptoms, TSH and free T4 may be appropriate for thyroid assessment, while blood pressure and waist circumference give us valuable information that doesn’t require a laboratory at all.

We’ll go much deeper into testing and metabolic disease in Article 4. For now, the purpose of testing isn’t to find something wrong with you.

It is to understand where you are starting from.

Your next step

For the next few weeks, I don’t want you hunting for a more complicated solution.

I want you to build the metabolic foundations.

Protect your muscle. Eat enough protein. Build better meals. Move throughout the day. Walk after meals when you can. Take your sleep seriously.

Then we can become more sophisticated.

Because once those foundations are in place, we can start asking more interesting questions: How can we improve insulin sensitivity further? Does meal timing matter? What about fasting? How should we use carbohydrates? What role do visceral fat, inflammation, stress physiology and the liver play?

That is exactly where we’re going next.
