How to Minimise Fat Gain Over the Festive Season — Without Missing Out
For women over 35 who want to enjoy Christmas, feel amazing, and stay on track with their metabolism
December can feel like a metabolic minefield — long lunches, late nights, cocktails, desserts, stress, travel, and a calendar bursting with social events. For many women in their late 30s to 50s, this is also a time when perimenopause, thyroid changes, and cortisol fluctuations make weight gain feel frustratingly easy.
But here's the truth: Fat gain over the festive season is not inevitable. You simply need a strategy — not restriction.
Instead of dieting your way through December (hello, burnout), the key is learning how to support your metabolism, reduce big glucose spikes, and enjoy the season without feeling like you've "blown it."
Let's walk through the simple, science-backed framework I teach my clients to minimise fat gain during the festive season — while still eating the foods you love.
Why Women Over 35 Store More Fat During December
Hormones shift. Stress rises. Sleep gets patchy.
And when cortisol and insulin are elevated together, your physiology becomes more biased toward storing energy, particularly around the belly.
Perimenopause and busy-mum-life also mean you may be more sensitive to sugar and alcohol than you used to be.
Your goal this season isn't perfection — it's keeping insulin steady and cortisol calmer so your body doesn't default into fat-storage mode.
And the small tweaks below do exactly that.
Step 1: Start Each Day With a Protein-Strong Breakfast
Aim for 25–30g of protein within the first hour of waking.
Why? Because a protein heavy breakfast does this:
stabilises blood sugar
reduces cravings later in the day
may support a healthier cortisol pattern over the day
improves energy
prevents afternoon snacking
Examples:
Protein smoothie
Eggs + greens
Greek yogurt with seeds
Leftover roast chicken on veg
Protein early in the day sets the tone for metabolic stability — especially during a month filled with high-sugar foods.
Step 2: At Events, Eat Your Protein FIRST (The Science Is Strong on This One)
This is one of the simplest and most powerful metabolic hacks you can use.
Research shows that eating protein before carbohydrates significantly reduces the glucose and insulin spike from the meal.
Why?
Because protein stimulates hormones like GLP-1, CCK, and PYY.
These hormones:
slow gastric emptying
tell your brain "I'm getting full"
reduce how much insulin your body needs
flatten the glucose spike from the carbs you eat next
often reduce cravings for sugar afterwards
Clinical trials have shown that eating protein (and vegetables) first can lower glucose by up to around 30–40% after the meal in some studies.
This is HUGE — especially for women over 35 whose insulin sensitivity naturally declines.
How to apply this at Christmas lunch:
Eat 3–5 bites of protein first
Then your vegetables
Then your healthy fats
Then your slow-release starch ("Anchor Carb")
Dessert last (if you still want it)
This tiny sequencing tweak can make a surprisingly big difference to how you feel after meals.
Step 3: Choose an "Anchor Carb" Instead of Sugar-Heavy Foods
Instead of grazing on sweets or loading up on multiple "treat" foods, choose one slow-release starch to anchor your plate.
Examples:
Roasted potatoes
Sweet potato
Pumpkin
Quinoa salad
Basmati rice
Lentil or chickpea salads
Why this works:
Potatoes (especially cooled) have the highest satiety index of all foods. When prepared simply, and especially when cooled and combined with protein and fibre, they can provide sustained energy and satiety.
They help reduce the size and speed of glucose and insulin spikes, keeping you full and reducing dessert cravings.
This festive carb strategy is FAR better than simply "limiting treats" — because it keeps your hormones more stable.
Step 4: Build Your Festive Plate in a Metabolism-Friendly Order
This is the plate formula my clients swear by:
1. Protein first Starts satiety hormones + reduces insulin spike.
2. Fibre / vegetables Can lower glucose spike by 20–40% in some studies.
3. Healthy fats Slow digestion + improve satisfaction.
4. Slow-release starch ("Anchor Carb") Keeps you full, reduces sugar cravings.
5. Dessert LAST (if you still want it) By this point, your insulin and cravings are calmer — and portion size naturally drops.
Step 5: Take a 10-Minute Walk After Your Biggest Meal
One of the MOST research-backed strategies to flatten glucose is a short walk within 20 minutes of eating.
This:
improves glucose clearance
can reduce the degree to which meals drive fat storage over time, especially when done regularly
improves digestion
stabilises energy
reduces inflammation
If you do one thing this season, let it be this.
Step 6: Prioritise Sleep Like It Matters (Because It Does)
Even one poor night of sleep increases hunger hormones the next day. Add alcohol? It can further disrupt sleep and appetite signals the next day.
Quick tips to try:
magnesium before bed
10-minute wind-down
stopping alcohol 2–3 hours before bed
earlier nights where possible
Better sleep = fewer cravings + less fat storage.
Step 7: Hydrate Properly on Party Days
Dehydration increases cravings and fatigue — and can aggravate histamine-related symptoms, which some women find worsen in perimenopause due to hormonal flux.
Before events:
Drink 500 ml water or electrolytes
Alternate alcohol with water
Herbal tea when home
Your liver will thank you.
BONUS: Your "Next Day Reset" Protocol
If you do indulge heavily (and you will at some point!), here's your gentle reset:
Protein-rich breakfast
2–3L water
Light movement
Lower-histamine foods
Early night
No guilt
You're simply helping your hormones rebalance.
The Takeaway: You Don't Need Willpower — You Need a Plan
Fat gain over Christmas happens not because you're "bad" or "undisciplined" — but because the festive season is a perfect storm for blood sugar instability, cortisol spikes, poor sleep, and inconsistent eating patterns.
With the right framework, you can enjoy the season fully and feel amazing in your body.
