What to Do When Your Middle Changes Overnight

I listened to a podcast this week where Dr Tyna Moore, a US naturopathic doctor, talked openly about gaining 7 to 9kg in a couple of months, almost all of it around her middle. A family crisis, a string of illnesses, a gut that wouldn't settle, and months of running on empty. Nothing fitted. Not even her wedding ring. Click here to listen.

I'd put money on a lot of you nodding along. I hear some version of this story all the time. "It happened almost overnight." "I haven't changed anything." "I don't recognise my own body."

So, if you went looking for a study showing that women in midlife can gain a substantial amount of fat around the middle in a matter of weeks during a period of severe stress, you'd come up short. Research just isn't set up to catch it. Trials don't recruit women in the middle of a crisis, and they rarely measure someone as life falls apart and then again three months later. Further, of course, in a crisis you are likely NOT getting to the gym, fitting in your steps or cardio, and meal prepping your protein options because you know that a ‘good diet doesn’t happen by accident.’ Plus, for some, the soothing effect of carbohydrate comfort foods and alcohol at the end of a day that leaves you frazzled will be adding fuel to the fire. When my mum passed earlier this year, and we had spent some months in the thick of that, an unravelling of sorts definitely happened for me. So listening to Tyna’s experience was something that resonated.

What we do have is good evidence for the pieces. The menopause transition shifts where we store fat (but in months, not weeks). Chronic stress and higher cortisol favour storage around the middle. Research in women under long-term caring stress suggests the same comfort foods may do more damage to your waistline and blood sugar when you're chronically stressed than when you're not (though I will say measuring cortisol levels is sketchy at best for ‘proving’ high stress). Poor sleep blunts insulin sensitivity (however interestingly, large association studies such as this find that abdominal fat and short sleep duration is more closely linked in men than women), and in small trials (NOT in menopausal women, FYI) we see that changes in insulin sensitivity occur before changes in body composition. Stress nudges what we eat toward snacky, high-sugar, high-fat foods and away from proper meals and vegetables. Stack all of that together, and it’s no wonder that in a period of high stress we feel like it all falls apart.

If you tune into that episode you’ll hear from Dr Tyna that she also had a gut infection and medication that would have contributed to the weight gain she experienced. That said, she has some excellent tips for how to bring yourself back into balance.

Ab work isn’t going to cut it. Crunches, planks and Pilates have their place, but they won't shift the fat sitting over or under your abdominal muscles. This is a whole-body metabolic situation and it needs a whole-body approach.

During periods of inactivity you lose muscle. Focus first on lifting before anything else. When muscle contracts, it pulls glucose out of your blood through a pathway that doesn't rely on insulin, which is exactly what you want when your body isn’t responding to insulin. Prioritise the big muscles: glutes, quads, hamstrings, back. Two or three sessions a week of steady, progressive strength work, building back what you might have lost. Muscle memory is real.

While it can get harder to build in midlife (this is called anabolic resistance) and progress will be slower than it was at 30, it’s still progress.

When your body feels out of control, the instinct is to slash food and punish yourself with cardio. I get it, and I say that as someone who trains harder than she probably should sometimes. You do not, however, want to layer stress upon stress. A big deficit and hard sessions stacked on an already maxed-out system tends to backfire: worse sleep, more hunger, more fatigue. Walk instead. Flat walks first, then hills or an incline as your energy comes back. If you finish a session feeling wrecked rather than better, dial it down. It’s better to keep these shorter at first and build on the distance.

Anabolic resistance means midlife muscle needs a stronger protein signal. If digestion is rough, go for the easier options: a whey smoothie, mince, chicken, eggs (if you tolerate), fish, Greek yoghurt. Spread it across the day rather than cramming it into dinner, and an essential amino acid powder can also be a good idea. While I don’t want to get into supplements, some digestive support (bitters, enzymes) can be helpful. Stress can impact on your stomach acid production, contributing to digestive issues (rodent trials show it lowers it, human data is mixed).

When life goes sideways, most of us reach for something. The nightly wine. The crackers eaten standing at the pantry. The 3pm sugar hit. No judgement from me, I'll happily have a glass of wine or a beer myself. But be aware if something has become the only way you can switch off at night. Alcohol in particular chips away at sleep quality and makes the next day's food decisions harder. Pull it back gradually if cold turkey feels like too much.

Recovery is where the adaptation happens. When sleep is poor, everything else gets harder: appetite, blood sugar control, training, mood. Protect your bedtime and get off the screens. If night sweats or 3am wake-ups are the problem, talk to your doctor about whether HRT is right for you.

A sudden change shouldn’t be ignored. Not all of us have the insight of a naturopathic doctor. Some of what's happening around your middle may be bloating and distension rather than fat, especially if you've been unwell, had antibiotics or a gut bug, or your digestion has changed. See your GP, get your bloods done (HbA1c, thyroid and iron studies are a good start) and bring up any gut symptoms.

It can be frustrating when you want to fix things overnight that it takes a little longer. Tyna shared that after 90 days of doing all the right things, her scale hadn't moved. Her DEXA scan showed she'd gained a little muscle and lost a little fat. That's a win, even when it doesn't feel like one. Track your waist, how your clothes fit, what you can lift, how you're sleeping and how you feel. The scale is often the last thing to catch up.

Regardless of how fast this can come on, unwinding it usually takes longer. That's frustrating, and it's also normal. The next decision is always yours to make: the next meal, the next session, the next early night. Stack enough of those and things start to move.
