The Hidden Habits Slowing Down Your Metabolism
"I'm doing the same thing but still putting weight on?!"
It genuinely just not fair - Do you ever wonder why you feel more tired, you live in leggings as your jeans are fitting tighter even though you’re “doing everything right,” you’re not alone. Your metabolism isn’t broken. It’s just responding to the habits that sneak into busy, full lives and losing muscle loses that speedy metabolism you had in your 20's when you could 'eat anything' and still be a size 8!
The good news? Small, powerful shifts can wake it up again — giving you more energy, easier fat loss, glowing skin and that strong, capable feeling everyone wants.
Your metabolism is your body’s internal engine — turning food into energy, powering every heartbeat, breath, and movement. When it’s running efficiently, you feel vibrant. When it slows, you feel sluggish, bloated, and frustrated by stubborn weight that seems to appear overnight, especially around the middle (that's cortisols fault!)
Here are five habits quietly slowing your metabolism — and exactly what to do instead:
1. Not Eating Enough Protein (The #1 Mistake)
Protein is your secret weapon, especially in your 30s and 40s. It keeps you full for hours, burns more calories during digestion and — most importantly — helps you build and maintain muscle - which burns more calories.
Here’s the truth: the more lean muscle you have, the faster your metabolism runs — even while you’re sitting at your desk or sleeping. Every pound of muscle burns roughly 6–10 extra calories per day at rest. That adds up fast.
Action step: Aim for 25–35g of protein at every meal. Think eggs, Greek yoghurt, salmon, chicken, lentils, or a Supernova Shake. (which is 20g of organic protein without the milk or any additions!)
2. Skimping on Sleep
Between work, kids, hormones, life admin and doom scrolling or Netflix binging, sleep often takes the hit. But less than 7 hours wrecks your hunger hormones (ghrelin and leptin), raises cortisol and can slow your metabolism by up to 20%.
Action step: Protect 7–9 hours like it’s a non-negotiable appointment with your future self. A consistent bedtime routine pays you back in energy and easier weight management. You'll be in a better mood, make better food choices and not dread the afternoon.
3. Living Too Sedentary (Even If You Exercise)
Many of us have active jobs… at a desk. Long periods of sitting tell your body to conserve energy and slow things down.
The fix isn’t just “exercise more.” It’s moving more throughout the day plus intentionally building muscle. Strength training 2–3 times a week (weights, resistance bands, or bodyweight) is one of the most effective ways to boost metabolism long-term because it increases that calorie-burning muscle tissue we talked about.
Action step: It's the small daily consistencies that add up - stand up every hour, take the stairs, go for walks and lift heavy things. Your future body will thank you.
4. Chronic Stress Running the Show
That constant low-grade stress ( perimenopause + career + family + teens + aging parents) floods your body with cortisol, which encourages fat storage around the middle and makes your metabolism sluggish.
Action step: Build in daily stress relief that actually works — 10 minutes of breathwork, a sunset walk, or lifting weights (yes, exercise can lower stress and build metabolism at the same time) yoga gardening - whatever calms your soul, prioritise it.
5. Crash Dieting & Undereating
Severe calorie restriction might work short-term, but it backfires hard after 35. Your clever body thinks there’s a famine and slows your metabolism to survive.
Action step: Fuel your body properly. Most women need around 2,000+ calories to keep their metabolism thriving (more if you’re active). Focus on quality and consistency rather than extremes.
Small Daily Choices = Big Transformation
You don’t need a total life overhaul. You need smart, sustainable habits that work with your body in this powerful new chapter.
Prioritise protein, protect your sleep, move daily, manage stress, and strength train. These aren’t just “health tips” — they’re the keys to feeling strong, energised in your 30s and 40s.
If hitting your protein target feels hard some days (we’ve all been there), a high-quality protein supplement like Supernova can be a total game-changer. It’s an easy, delicious way to support muscle maintenance, keep hunger in check, and give your metabolism the consistent fuel it needs. Plus our magic ingredients, high fibre and GLP boost, organic psyllium husk - keeps you super full for hours and hours which is amazing for weight management and reducing that 'food noise.'
You deserve to feel amazing in your body — not despite your age, but because of how intentionally you’re living right now.
