Keto and Hormone Health After 40 | Colbert Institute
Monday, January 26, 2026 | By: Colbert Institute of Anti Aging
As women enter their 40s, hormonal shifts are natural but can bring unwanted changes like stubborn belly fat, mood swings, disrupted sleep, and dips in energy. These changes aren’t “just aging”—they’re a reflection of hormonal biology at work. Understanding how your hormones interact with diet, activity, and lifestyle can help you feel more in control and maintain wellness through midlife and beyond.
One approach gaining popularity is the ketogenic, or “keto,” eating pattern. Keto encourages the body to burn fat instead of sugar for fuel, which may help balance blood sugar, support metabolic health, and reduce fat storage. While keto isn’t a cure-all, when combined with nutrient-dense foods, proper stress management, and quality sleep, it can be a powerful tool to support better energy, hormonal balance, and overall wellness.
How Hormonal Shifts Affect Your Body
During your 40s, estrogen and progesterone levels fluctuate, sometimes leading to:
- Increased abdominal fat and changes in body composition
- Energy slumps or afternoon crashes
- Difficulty sleeping or staying asleep
- Mood changes, including irritability or low motivation
These changes can make it harder to maintain your weight and feel your best. The good news is that a targeted lifestyle approach—including diet, movement, and sleep—can help offset many of these shifts and support long-term health.
Keto as a Tool for Metabolic and Hormonal Support
A well-designed ketogenic eating pattern emphasizes high-quality fats, moderate protein, and lower carbohydrate intake. This encourages your body to burn fat for energy rather than relying primarily on sugar. Benefits of a keto approach can include:
- Improved blood sugar control: Stabilizing glucose levels can reduce cravings and support energy throughout the day.
- Enhanced fat metabolism: Using fat for fuel may help reduce stubborn fat, especially around the midsection.
- Hormonal support: Stable blood sugar and lower insulin levels can positively influence estrogen and other hormones.
Through the Keto Zone weight loss program, Dr. Colbert at the Colbert Institute of Anti-Aging works with women to create a personalized keto plan tailored to their preferences, health goals, and lifestyle. This program provides a balanced, sustainable approach that supports metabolic health, hormonal balance, and long-term wellness. Dr. Colbert serves patients in Lake Mary, Florida, and Southlake, Texas.
Focus on Whole Foods
Keto works best when paired with nutrient-dense, minimally processed foods. Choosing whole foods helps provide essential vitamins, minerals, and fiber while reducing inflammation that can interfere with hormonal balance. Key recommendations include:
- Healthy fats like avocado, olive oil, nuts, and seeds
- High-quality protein from fish, poultry, eggs, or plant-based sources
- Low-carb vegetables such as leafy greens, broccoli, and cauliflower
- Limited, carefully chosen fruits like berries for antioxidants and fiber
Eating this way supports not only hormonal and metabolic health but also cardiovascular and gut health, which are important as women age.
Lifestyle Strategies That Complement Keto
While nutrition plays a central role, lifestyle factors amplify results and promote hormonal balance:
-
Sleep: Prioritize consistent bedtimes, a dark and cool bedroom, and a screen-free wind-down routine. Quality sleep supports cortisol regulation and improves energy.
-
Stress management: Chronic stress can disrupt insulin and cortisol levels, making hormonal changes harder to manage. Techniques like meditation, yoga, or short walks outdoors can help.
-
Physical activity: Resistance training and aerobic exercise improve metabolism, maintain muscle mass, and support weight management. Even daily movement like brisk walking or stretching has measurable benefits.
Dr. Colbert guides patients to integrate these strategies in ways that fit their routines and lifestyles, focusing on practical, achievable steps rather than drastic changes.
Monitoring Progress and Making Adjustments
Every woman’s hormonal profile and lifestyle needs are unique. Regular check-ins and tracking outcomes like energy levels, sleep quality, mood, and body composition help ensure the approach is working. Adjustments can be made to carbohydrate intake, food choices, and lifestyle habits as needed to maintain progress and support long-term wellness.
When to Seek Additional Support
Sometimes, women need guidance beyond nutrition and lifestyle changes. Persistent fatigue, unexpected weight gain, or ongoing mood changes may signal it’s time for extra support. Counseling, coaching, or a medical evaluation can provide tools and accountability to help you get back on track.
Dr. Colbert and the team at the Colbert Institute in Lake Mary and Southlake work with patients to develop individualized plans. These plans combine nutrition, lifestyle habits, and medical strategies to achieve optimal results.
Take Charge of Your Hormonal Health
Hormonal shifts after 40 are natural, but they don’t have to control how you feel. By combining a thoughtful ketogenic-style diet with nutrient-rich whole foods, stress management, quality sleep, and regular physical activity, women can support their metabolic and hormonal health.
