28-Day Get-Lean Diet for Women Over 40: Your Path to Lasting Wellness

As women move past 40, managing a healthy weight can become uniquely challenging. The 28-Day Get-Lean Diet for Women Over 40 is a comprehensive, expertly designed program tailored to address the physical, hormonal, and lifestyle changes that come with this new chapter. Rather than drastic overhauls or restrictive plans, it provides simple, sustainable strategies for losing weight and feeling energized — without turning your life upside down.

Why Weight Loss Changes After 40

Hormonal shifts, busy lifestyles, and age-related metabolic changes often mean the weight management strategies that worked in your 20s and 30s no longer bring the same results. Many women experience:

Slow metabolism, making it easier to gain weight and harder to lose it
Shifting hormones that may affect hunger, fat storage, and energy
New challenges from perimenopause and menopause, including increased cravings and disrupted sleep
Less time for self-care due to busy work, family, or caregiving roles

Recognizing these realities is the first step toward a plan that truly fits this phase of life.

What Is the 28-Day Get-Lean Diet?

This four-week program, developed in collaboration with registered dietitians and reviewed by Prevention’s editorial team, is not a crash diet. Instead, it focuses on cultivating eight essential habits, enjoying real food, and embracing an approach that aligns with the needs and schedules of women over 40. The aim: put an end to age-related weight gain, boost energy, and help you feel strong and confident—now and for the future.

Inside the 28-Day Get-Lean Diet: Overview of the Program

Here’s a closer look at what you receive and how each element supports your goals.

1. Simple, Tasty Meal Planning

Each week features a detailed meal plan with over 50 palate-pleasing recipes that make healthy eating enjoyable rather than a chore.
Meals are packed with lean protein, fiber, phytoestrogens (plant compounds that naturally support hormone balance), and healthy fats to promote satiety and steady energy levels.
Recipes and plans are flexible, allowing for real-life changes and preferences.

2. Eight Core Habits for Lifelong Change

Beyond just what’s on your plate, lasting weight loss is about the little things you do consistently. The plan distills the science of healthy living into eight habits—small but meaningful daily shifts that make weight management after 40 more achievable:

Habit	What It Means	Why It’s Effective
Meal Prep Rituals	Plan and prep meals or snacks in advance	Prevents unhealthy last-minute choices
Protein Focus	Add protein to every meal and snack	Supports muscle, reduces hunger swings
Fiber First	Prioritize fruits, veggies, and whole grains	Boosts fullness and gut health
Smart Fats	Incorporate sources like nuts, olive oil, and avocado	Balances hormones, sustains energy

3. Weekly Grocery Lists & Shopping Tips

The right foods in your kitchen set the stage for success. Each week, you’ll have a pre-made grocery checklist that ensures nutritional balance, variety, and convenience. The plan:

Covers all core food groups—protein, fiber, vegetables, healthy fats, and whole grains
Highlights sensible, affordable foods you can find at any major store
Offers “swap” suggestions if you have dietary restrictions or strong preferences

4. Smart Strength & Fitness Guidance

Loss of lean muscle naturally accelerates after 40, but strength and resistance training can halt and even reverse this trend. The program includes:

Easy-to-follow, equipment-optional routines tailored for beginners and experienced exercisers
Tips for fitting short, effective workouts into even the busiest schedule
Guidance on mixing cardio, stretching, and resistance for optimal results

5. Sleep and Recovery Strategies

Quality rest isn’t just a luxury—it affects hunger hormones, mood, fat loss, and energy.

Discover simple sleep hygiene tweaks, such as consistent bedtime, minimizing screen time, and calming rituals
Explore the impact of stress and strategies for bouncing back after setbacks

Special Focus: Navigating Perimenopause & Menopause

This plan is specifically attuned to the realities of perimenopause and menopause. It addresses:

Hormone-related food cravings and how to manage them
Hot flashes, insomnia, and their impact on weight management
Key nutrients (like calcium, magnesium, and omega-3s) needed at this stage

How Does the 28-Day Get-Lean Diet Work?

Start by reviewing the eight core habits and choose two to implement in your first week. After all, true change is about building, not overwhelming yourself.
Follow the simple meal plans for inspiration, but remember you can swap in family favorites or enjoy meals out—perfection is not the goal, progress is.
Check off your habits and meals each day using the included trackers. This small action helps cement new routines and keeps you honest about what’s working or isn’t.
Re-assess each week. Pick a new habit to add or double-down on the ones that feel hardest. Use the grocery lists to get set up for another week of tasty, nourishing food.
Prioritize movement and sleep. Short, regular workouts and improved sleep are just as important as the food you eat.

Snack: Apple slices with almond butter
