She was doing three strength sessions a week. Walking on her off days. Eating well. Sleeping better than she had in years.
And she spent the rest of her time sitting. At a desk for eight hours. On the couch in the evenings. In the car between commitments. Like most people in modern life, her days were structured around periods of sitting interrupted by scheduled exercise, and nothing much else in between.
When we talked about NEAT – Non-Exercise Activity Thermogenesis, the energy the body burns through all the movement that isn’t formal exercise – she looked slightly stunned.
“I had no idea that mattered,” she said. “I thought if I was doing my workouts, that was enough.”
It’s a reasonable assumption. And it’s one that the fitness industry has quietly reinforced for decades, by focusing almost entirely on structured exercise while overlooking the movement that fills, or fails to fill, the other twenty-two or so hours of the day.
The research tells a different story. And once you understand it, the way you approach your whole day changes.
What NEAT Actually Is
NEAT stands for Non-Exercise Activity Thermogenesis. Thermogenesis simply means heat production, and in this context, it refers to the energy the body burns generating that heat through movement. Specifically, all the movement that is not deliberate, structured exercise.
NEAT includes:
- Walking around the house, office, or garden
- Standing rather than sitting
- Taking stairs rather than lifts
- Fidgeting, shifting position, gesturing while talking
- Cooking, cleaning, gardening, grocery shopping
- Playing with children or grandchildren
- Any spontaneous, incidental movement throughout the day
In sedentary people, NEAT may contribute as little as 15 percent of total daily energy expenditure. In highly active people, those who move consistently throughout their day in addition to formal exercise, NEAT can account for up to 50 percent of total energy burn.
A landmark study by Dr James Levine at the Mayo Clinic found that NEAT varied by up to 2,000 calories per day between individuals of similar size, body composition, and formal exercise habits. The difference was not their workouts. It was everything else.
Why NEAT Matters More After 40
The significance of NEAT increases as we age for several interconnected reasons.
Resting metabolism slows
As muscle mass declines from the mid-30s onwards, the body’s resting metabolic rate, the number of calories it burns simply existing , decreases. This means the same amount of formal exercise produces a proportionally smaller contribution to total energy expenditure than it did at 30. NEAT becomes an increasingly important way to maintain metabolic activity across the whole day rather than concentrating it in a single session.
Sedentary time has its own metabolic consequences
Prolonged sitting is not simply the absence of movement, it is an active physiological state with specific metabolic consequences. Research has shown that sitting for extended periods suppresses the activity of an enzyme called lipoprotein lipase, the enzyme responsible for breaking down fat in the bloodstream for use as energy. Even people who exercise regularly show this suppression if they sit for long unbroken periods between sessions.
In other words: a one-hour workout does not fully compensate for eight hours of sitting. The two are separate physiological variables, not interchangeable ones.
Insulin sensitivity is affected by movement frequency
Breaking up sitting time with regular short bouts of movement, even just standing or walking for two to five minutes every hour, has been shown to meaningfully improve blood sugar regulation and insulin sensitivity throughout the day. For women over 40, whose insulin sensitivity is already under pressure from hormonal change, this is a significant and practical lever.
A study published in the journal Diabetes Care found that short walking breaks after meals reduced blood sugar spikes by up to 30 percent compared to uninterrupted sitting. Three ten-minute walks after meals produced a more significant improvement in blood sugar regulation than a single thirty-minute walk at a different time of day.
What Are Movement Snacks?
Movement snacks are exactly what they sound like, short, intentional bursts of movement woven into the ordinary moments of the day. Not workouts. Not sessions. Just deliberate choices to move rather than stay still, taken consistently enough to add up to something meaningful over the course of a day, a week, a year.
The concept has strong research support. A study published in Applied Physiology, Nutrition, and Metabolism found that three one-minute bouts of stair climbing per day, performed on three days per week, measurably improved cardiovascular fitness over six weeks. One minute. Three times a day. Meaningful results.
Movement snacks work because the body responds to the frequency of movement stimulus, not just to the duration or intensity of formal exercise sessions. And because they are brief and woven into what you’re already doing, the barrier to doing them is almost zero.
Practical Movement Snacks to Start Today
At home
- Do ten squats or calf raises while the kettle boils
- Walk around the house or garden during phone calls rather than sitting
- Stand and do a set of wall push-ups while waiting for food to heat
- Take the stairs rather than any lift, every time
- Do a two-minute stretch or mobility flow when you first get out of bed
- March on the spot or do standing hip circles during ad breaks
At a desk
- Set a timer to stand and move for two minutes every hour, a short walk to the kitchen, a set of standing stretches, or simply standing and shifting your weight
- Take all calls standing or walking rather than sitting
- Position your printer, water bottle, or frequently used items away from your desk so you have to get up to reach them
- Do seated or standing shoulder rolls, neck stretches, or ankle circles between tasks
- Use a standing desk or elevated surface for part of your working day if available
Out and about
- Park further away than you need to, every time
- Get off public transport one stop early and walk the rest
- Take the longest walking route between destinations rather than the most direct
- Walk while you wait, at school pick-up, at appointments, any time you’d otherwise stand still
- Carry groceries rather than using a trolley for smaller shops, functional carrying is resistance training in disguise
The 10-Minute Movement Snack Protocol
For women who want a slightly more structured approach, here is a simple ten-minute movement snack that can be done anywhere, requires no equipment, and delivers genuine metabolic benefit:
- 2 minutes: walk briskly on the spot, swinging arms
- 1 minute: squats (bodyweight, any depth that feels comfortable)
- 1 minute: wall push-ups or full push-ups
- 1 minute: standing side leg raises (each side)
- 1 minute: calf raises
- 1 minute: standing hip circles
- 1 minute: overhead arm reaches with a deep breath
- 2 minutes: slow walking to bring the heart rate down
Done twice a day, once mid-morning and once mid-afternoon, this adds twenty minutes of intentional movement to your day without touching your scheduled training. Over a week, that is an additional two hours and twenty minutes of movement your body wasn’t getting before.
NEAT and the Strong Calm Lean Method
Strength training is the foundation of the Strong Calm Lean Method, it builds the muscle that drives metabolic health, supports hormonal balance, protects bone density, and creates the physical resilience that carries women powerfully through midlife and beyond.
But the strength sessions alone are not the whole picture. The movement between them, the NEAT, the movement snacks, the deliberate choice to walk rather than sit, to stand rather than slump, to use your body throughout the day rather than only in designated exercise windows, is the environment in which those sessions operate.
A body that moves consistently throughout the day is more insulin-sensitive, more metabolically active, less inflamed, better hydrated, and more physically capable than one that exercises for an hour and then sits for the rest of it. The workout is the stimulus. The movement between is the context that determines how well the stimulus lands.
You don’t need more time. You need more movement in the time you already have.
