Why This Plan Supports Women Over 40
If you've tried a weight loss shake programme before and it didn't work — or it worked for a few weeks and then stopped it was the wrong plan.
Most weight loss programmes are built for a generic body. Eat less, lose weight. Simple. But for women in perimenopause and menopause, that equation breaks down fast. Falling oestrogen shifts fat to your abdomen. Disrupted sleep raises cortisol and drives cravings. Muscle mass starts to decline — and a low-calorie plan without enough protein makes that worse, not better.
Three Principles Run Through Every Week Of This Plan
Protein first.
Every meal — shake or otherwise — is anchored around protein. It protects muscle, keeps you full, and supports the metabolic function that tends to decline through menopause.
Blood Sugar Balance
Hormonal changes make blood sugar harder to regulate. Erratic blood sugar drives cravings, energy crashes, and abdominal fat storage. The food choices in this plan are designed to keep things steady.
Sustainability Over Speed.
The goal isn't to lose weight as fast as possible. It's to lose fat, keep muscle, and build habits that hold beyond week four.
Nutritionist Insight
"For many women in midlife, protein needs do increase slightly. As we get older, the body becomes a bit less efficient at using protein to maintain muscle, which is why it becomes more important to include it regularly. At the same time, many women aren’t getting enough across the day to support how they want to feel."

Before You Start Your Plan
Know Your Protein Target
Every meal — shake or otherwise — is anchored around protein. It protects muscle, keeps you full, and supports the metabolic function that tends to decline through menopause.
Get Your Shakes Sorted
You'll need a meal replacement shake formulated for midlife — not a generic diet shake. The Eve Biology Rebalancing Shake is built specifically for women over 40: high protein, gut-supportive, with adaptogens, vitamins and minerals.
Set Realistic Expectations
Week one will feel different to week four. Give the plan time to work. We recommend weekends eat healthy balanced meals and keep active then on weekdays return to the shakes.
Week 1: Reset
| Time | Meal | What to eat | Why |
|---|---|---|---|
| 7:30am | Breakfast | Rebalancing Shake | High protein start stabilises blood sugar and reduces mid-morning cravings |
| 1:00pm | Lunch | Rebalancing Shake | Slow-release carbs alongside protein prevents the afternoon energy crash common in menopause |
| 7:00pm | Dinner | Creamy Stuffed Chicken Breasts with vegetables | Fats in the evening support hormone production and help you feel satisfied overnight |
| As needed | Snack | Greek yoghurt, a small handful of nuts, or boiled eggs | Protein-rich snacks prevent blood sugar dips without spiking insulin |
Week 2: Build
| Time | Meal | What to eat | Why |
|---|---|---|---|
| 7:30am | Breakfast | Rebalancing Shake | Consistent protein at breakfast anchors your appetite for the rest of the day |
| 1:00pm | Lunch | Rebalancing Shake | Hitting a protein target at lunch protects muscle mass and keeps cortisol in check |
| 4:00pm | Snack (optional) | Only if genuinely hungry — Greek yoghurt, nuts, or boiled eggs | Eating only when hungry helps recalibrate hunger signals disrupted by hormonal changes |
| 7:00pm | Dinner | Pistachio and Herb Encrusted Salmon | A structured dinner prevents late-night snacking, a common driver of abdominal fat gain in menopause |
Week 3: Optimise
| Time | Meal | What to eat | Why |
|---|---|---|---|
| 7:30am | Breakfast | Rebalancing Shake | The habit is now established — breakfast is handled, freeing mental energy for the rest of the day |
| 1:00pm | Lunch | Rebalancing Shake (optional) or structured lunch | A second shake can accelerate fat loss — but only if you're well-fuelled overall and not under-eating |
| 7:00pm | Dinner | Deceptively Healthy Lasagne | A full dinner is worth protecting — fibre and protein in the evening can also improve sleep quality |
Week 4: Sustain
| Time | Meal | What to eat | Why |
|---|---|---|---|
| 7:30am | Breakfast | Rebalancing Shake | One shake a day as a long-term anchor — simple, consistent, and nutritionally complete for midlife women |
| 1:00pm | Lunch | Protein-anchored, whatever works for your day | Flexibility at lunch makes this sustainable — the protein principle holds, the meal adapts to your life |
| 7:00pm | Dinner | Balanced, protein-rich, fibre-filled, enjoyable — not tracked | By week four, good choices should feel natural — dinner is about nourishment and enjoyment, not rules |
Focus this week on identity, not rules. You're someone who eats well for your body — the shake is just part of that.
What To Eat When You're Not Using Shakes
Prioritise: protein at every meal (chicken, fish, eggs, legumes, tofu), fibre (vegetables, lentils, oats, berries), healthy fats (olive oil, avocado, nuts, oily fish), and at least 2 litres of water a day.
Reduce — not eliminate: ultra-processed foods, refined carbohydrates, added sugars, and alcohol. Alcohol disrupts sleep, raises cortisol, and stalls fat loss disproportionately in midlife.

Common Diet Mistakes
Not eating enough protein.
A calorie deficit without adequate protein leads to muscle loss. Muscle loss slows your metabolism. This is the most common reason women plateau or feel worse on a weight loss shake programme.
Shakes with excess sugar, maltodextrin and tapioca flour
These ingredients are used to improve flavour and texture and there is nothing wrong with them. However they all can raise blood sugar quickly which release stress hormones and steal your energy. Not what you want when you're dealing with hormone instability.
Lack of movement.
Notice we didn't say exercise? We said movement. Walking, calf raises, squats, few wall press-ups. They're all there to help support your blood sugar and muscle mass which helps to support your metabolism.
Snacks with low nutrient density.
If you feel like you need a snack between shakes or meals that's ok. The key is to focus snacks with protein and healthy fats which can hit that satisfaction button while supporting blood sugar balance. Boiled eggs, turkey and avocado rolls, biltong and almonds.
Expecting linear progress.
Weight fluctuates daily — water retention, hormonal cycles, stress. Judge the plan over weeks, not days.
Stopping when it gets hard.
Weeks two and three are often the hardest. The habit isn't automatic yet, the weight loss results can slow. This is the gap where most people quit. Don't. Because weeks three and four is where women tell us their sleep improves. Its also where we start to see our prebiotic fibre makes it's impact.
FAQ
How Many Pouches Are In A 4 Week Plan?
You'll need 3 pouches for a 4 week weight loss plan. Each pouch contains 15 meals. 2 meals per day Monday to Friday (10 meals per week)
Can I replace two meals a day?
Yes. Replacing two of your main daily meals with a shake supports weight loss, replacing one supports weight maintenance. We recommend replacing breakfast and lunch. Snacks are optional. Evenings enjoy a hearty, protein rich meal with fibre and healthy fats. Our nutritionists have written some family friendly meals which also happen to support hormone balance HERE
Will I lose muscle?
Not if your protein intake is high enough. Aim for at least 1.6g per kg of bodyweight per day — and make sure every meal, shake or otherwise, contributes to that target.
How long should I follow this plan?
The 4-week structure is a starting point. Many women continue with one shake a day indefinitely as part of a balanced diet — that's a healthy, sustainable approach.
Is this safe during perimenopause or menopause?
For most women, yes. If you're on HRT or other medication, check with your GP before making significant dietary changes.
What if I'm not losing weight?
Check protein first. Then sleep — poor sleep raises cortisol and stalls fat loss. Then overall food quality. If everything looks right and nothing is moving after three weeks, speak to a nutritionist or your GP.
Can I do this diet if I'm on HRT?
Yes. Our shakes are HRT friendly. Consult your healthcare professional for advice and reassurance if you need it.
