You are eating what you have always eaten. You walk as much as you did. Still the waistband of your shalwar needs letting out, and a relative at a dinner mentions it before you do.
This is not a lack of willpower, and the guidance is plain about it.
The numbers
The Study of Women's Health Across the Nation (SWAN), which has followed women through midlife for decades, found women gain about 1.5 pounds (around 0.7 kg) a year during the menopause transition, over and above ageing alone. Across the years of perimenopause, that can add up to roughly 2 to 7 kg, with a lot of variation between women. SWAN also found that fat around the organs increases during the transition, even in women whose weight hardly changes.
Muscle goes the other way. The American College of Sports Medicine puts muscle loss at 3 to 8% a decade after the age of 30, faster after 40. Less muscle means your body burns less at rest.
Why the weight moves to the middle
There is no single cause. Several changes land at once.
Estrogen. The British Menopause Society calls weight gain one of the most common changes in perimenopause and after. It says most of it settles around the abdomen and upper body, because as estrogen falls, fat around the organs increases while muscle reduces and metabolism slows. The pear shape of your thirties drifts towards an apple.
Muscle. Eat exactly as you did at 35 with less muscle, and the weight creeps up at 50 even if nothing else changes.
Insulin. Your body becomes less sensitive to insulin in these years, so it needs more of it to handle the same meal, and higher insulin makes it easier to store fat around the middle. This is one reason calorie counting alone often stops working.
Sleep. Night sweats and broken sleep raise the hormone that makes you hungry and lower the one that tells you you are full. After a bad night, the craving for something sweet with your chai is not imagined.
Stress. Long-term stress raises cortisol, which also pushes fat towards the middle and makes rich food more tempting. Midlife often brings a demanding job, ageing parents and teenagers at once.
Why it matters more here
There are two kinds of fat around the middle. The fat you can pinch sits under the skin and does relatively little. The fat packed around your organs is active: it feeds insulin resistance, inflammation and heart risk. Two women of the same weight can carry very different risk depending on where it sits.
The Pakistan Menopause Society lists central fat, insulin resistance and heart risk among the longer-term changes after menopause. NICE's guidance on overweight and obesity, NG246, says people of South Asian background are prone to fat around the middle, and that their risk of heart disease and diabetes rises at a lower BMI. Fat around the middle matters for your heart and your blood sugar, far more than for how a dress fits. The BMS suggests measuring your waist, hips and bust, and noticing how clothes fit, as well as weighing yourself.
What helps
Strength work. The BMS says regular resistance exercise, the kind that works your muscles against a weight, builds muscle and raises metabolic rate. The NHS suggests muscle-strengthening activity on at least two days a week. Bands, bottles of water and your own body weight all count. Movement That Meets You has ideas.
Steady eating, not crash diets. The BMS warns that the evidence behind popular diets is thin and that weight lost on them is likely to come back. Severe cutting tends to cost you muscle, which makes the problem worse. Women's Health Concern, the BMS's patient arm, suggests a regular eating pattern over long gaps without food.
Kitchen changes the whole family shares. The Pakistan Menopause Society's recommendations are written for Pakistani kitchens. They say sweetened drinks and colas drive central weight gain and metabolic risk, and encourage whole grains, dals, fish and eggs, and dishes such as saag, moong dal and channa. On white rice and maida, Women's Health Concern says refined starches such as white rice and white bread have a place in a healthy diet and need not be avoided, and suggests making more of your starchy food wholegrain. Food is how many families show love, so a change sticks best when everyone eats it. The same recommendations count shared healthy habits with your husband and family as part of menopause care.
Sleep and stress. Both drive appetite, so a cooler bedroom, less caffeine late in the day and a real break in the day all feed into your weight.
Protein: the change most women miss
If one food change pays off in midlife, it is protein: how much you eat, and when.
The standard recommendation, 0.8 g of protein per kilo of body weight a day, was set as the minimum to avoid deficiency in young adults. Research by Dr Paul Arciero at Skidmore College, and the wider research on protein and ageing, points to around 1.2 to 1.6 g per kilo for midlife women, and more for women doing strength training. For a 70 kg woman, that is about 84 to 112 g a day.
Spread it out. Muscle responds best to around 25 to 35 g of protein at a meal, and the body cannot store a large helping at dinner for later. Arciero's work on "protein pacing", spreading protein across four to six servings a day alongside strength and interval training, found real improvements in body shape in middle-aged adults.
Start with breakfast, which for many of us is paratha and chai. Some everyday sources, roughly:
- one egg: about 6 g
- a bowl of cooked dal or channa: about 9 to 15 g
- a cup of dahi: about 8 g
- 100 g of chicken or fish: about 25 to 30 g
- 100 g of paneer: about 18 g
If you have kidney disease, ask your doctor before you raise your protein.
Your doctor's part
NICE NG23 and the Pakistan Menopause Society both list HRT as a first-line option for hot flushes and night sweats, which are often what is breaking your sleep. Whether it fits you is your doctor's call.
Questions women ask
Why am I gaining weight around my stomach?
As estrogen falls, the body stores more fat around the organs and less on the hips and thighs, while muscle reduces. It can happen even when your weight stays the same.
Can it be reversed?
Your shape can change for the better even when the scales are slow to move. Strength work, enough protein spread across the day, better sleep and steadier eating are where the evidence points.
How do I know what is working?
Write it down. Weight, waist size, sleep and what you ate, side by side for a few weeks, show you what is moving and what is not.
Ask for a check
If the weight has gone to your middle, especially with diabetes, heart disease or high blood pressure in the family, ask your doctor: "Should my blood pressure, blood sugar and cholesterol be checked?" The Pakistan Menopause Society asks doctors to record weight and waist size and to consider those tests. Losing weight without trying is different: see a doctor rather than waiting.
