As women enter their 40s and beyond, many find themselves struggling with unexplained weight gain, particularly around the midsection, buttocks, and back of the arms. While hormonal changes play a significant role, another crucial factor that often goes overlooked is blood sugar regulation.
Understanding the intricate relationship between blood sugar and weight can be the key to unlocking sustainable weight management for women in this age group, and any age group, really.
The Blood Sugar-Weight Gain Connection
Blood sugar, or glucose is our body’s primary source of energy. When we consume carbohydrates, our body breaks them down into glucose, which enters the bloodstream. In response, the pancreas releases insulin, a hormone that helps cells absorb glucose for energy or storage.
As we age, our bodies may become less sensitive to insulin, a condition known as insulin resistance. This means that more insulin is needed to manage blood sugar levels effectively.
Basically, having excess insulin in the bloodstream can increase fat storage, particularly in the abdominal area. (1).
What is Insulin Resistance?
Insulin resistance occurs when cells in your muscles, fat, and liver don’t respond well to insulin and can’t easily take up glucose from your blood. As a result, your pancreas produces more insulin to help glucose enter your cells. Over time, this can lead to higher blood sugar levels and eventually type 2 diabetes.
How Does Insulin Resistance Lead to Weight Gain?
When insulin levels are high, the body is more likely to store fat, especially in the abdominal area. This is because insulin promotes fat storage and prevents fat breakdown. Additionally, high insulin levels can increase hunger and cravings, leading to overeating and further weight gain.
Why Women Over 40 Are More Susceptible
Several factors make women over 40 more prone to blood sugar imbalances and subsequent weight gain:
Hormonal Changes: The decline in estrogen during perimenopause and menopause can affect insulin sensitivity. Estrogen plays a role in how the body responds to insulin, and lower levels can lead to increased insulin resistance. (2)
Muscle Loss: Natural age-related muscle loss (sarcopenia) can decrease the body’s ability to regulate blood sugar effectively. Muscle tissue is more metabolically active than fat tissues, so losing muscle mass can slow down metabolism and impair glucose regulation. (3)
Stress: Increased life stressors can elevate cortisol levels, which in turn can raise blood sugar. Chronic stress can lead to prolonged high levels of cortisol, which can cause insulin resistance and weight gain. (4)
Sleep Disturbances: Poor sleep, common in this age group, can disrupt glucose metabolism. Lack of sleep can affect the hormones that regulate hunger and appetite, leading to increased cravings and poor food choices. (5)
Hormonal Changes and Insulin Sensitivity
During perimenopause and menopause, estrogen levels fluctuate and eventually decline. Estrogen has been shown to have a protective effect on insulin sensitivity. Lower estrogen levels can lead to increased fat storage, particularly in the abdominal area, and make it more difficult to manage blood sugar levels.
The Role of Cortisol in Blood Sugar Regulation
Cortisol, known as the stress hormone, is released in response to stress. It helps the body manage and use carbohydrates, fats, and proteins and keeps inflammation down. However, chronic stress can lead to consistently high cortisol levels, which can increase blood sugar levels and promote fat storage.
What Can You Do?
Managing blood sugar levels and preventing weight gain involves making lifestyle changes that focus on diet, exercise, stress management, and sleep. Here are some strategies.
Prioritize protein and fiber: These nutrients help slow down glucose absorption and promote satiety. Protein helps maintain muscle mass, which is crucial for metabolism. Fiber slows the digestion of carbohydrates, leading to a more gradual release of glucose into the bloodstream.
Embrace Healthy fats: This macro nutrient provides fuel for the body, helps keep the skin subtle and youthful, and helps regulate hormones. Healthy fats, such as those found in avocados, nuts, seeds, and olive oil, can also help you feel full and satisfied. (6)
Regular Exercise: Ladies, you must add resistance training and some cardio. Stop the cardio Queen madness of the 80s and add in some resistance training to improve insulin sensitivity and hold onto muscle mass. Doing too much HIIT Training can deter your progress too.
Manage Stress: Incorporate stress reduction techniques like meditation, yoga, or walking out in nature into your daily routine. These activities can help lower cortisol levels and improve overall health.
Prioritize sleep: Aim for 7-8 hours of quality sleep every night. Adequate sleep is critical for weight loss and overall health. Poor sleep can disrupt hormones that regulate hunger and appetite, leading to increased cravings and poor food choices.
Prioritize Protein and Fiber:
Examples of High Protein Foods are lean meats, fish, eggs, and dairy products.
Examples of High Fiber Foods are whole grains, fruits, vegetables, nuts, and seeds.
Embrace Healthy Fats:
Examples of Healthy Fats are avocados, olive oil, nuts, seeds, and fatty fish like salmon and mackerel.
Regular Exercise:
Resistance Training: Incorporate exercises like squats, lunges, push-ups, and a variety of dumbbells, barbells, and bands. Aim for 2-3 days a week at least of resistance training per week. I cannot express enough how important resistance training is, especially in your 40s and beyond.
Cardio Exercise: Including activities like brisk walking, cycling, swimming, boxing, etc. Aim for at least 60-90 minutes of moderate-intensity cardio per week.
Manage Stress:
Meditation: Practice mindfulness meditation for 10-15 minutes daily to reduce stress and improve mental clarity
Yoga: Engage in yoga sessions to improve flexibility, strength, and relaxation
Nature Walks: Spend time outdoors walking in nature to reduce stress and improve moods.
Prioritize Sleep:
Sleep Hygiene Tips: Establish a regular sleep schedule, create a relaxing bedtime routine, limit screen time before bed, and ensure your sleep environment is comfortable and conducive to rest.
Above all, by understanding and addressing the role of blood sugar in weight management, women over 40 can take control of their health and achieve sustainable weight loss. It is always recommended to consult with your trusted healthcare professional before beginning any new exercise routine, especially if you have any injuries or health concerns.
