UNDERSTANDING THE CAUSES OF WEIGHT GAIN IN YOUR 40S AND HOW TO COMBAT IT

Are you noticing that your clothes are getting tighter and your scale is showing a higher number as you enter your 40s? If so, you are not alone. Many people experience weight gain in midlife due to various factors that affect their body composition, metabolism, and lifestyle. 

However, this does not mean that you have to accept it as inevitable. By understanding the causes of weight gain in your 40s, you can take proactive steps to combat it and maintain a healthy weight.

Factors Contributing to Weight Gain in your Mid-40s

As you age, your hormones change, and this is the single biggest factor known to affect your propensity for gaining weight during your mid-40s.

For women, menopause causes a decline in estrogen levels, which can result in increased fat storage in the abdomen, hips, and thighs.^[1] For men, testosterone levels start declining gradually, which can impact muscle mass and promote body fat.^[2] These hormonal changes also influence many other aspects of your metabolism that can affect your appetite, mood, and energy levels, further contributing to unintentional weight gain.

Other factors that can cause weight gain due to hormonal changes in one’s mid-40s are discussed below.

Muscle Loss and Slowing Metabolism

Muscle is metabolically more active than fat, i.e., it uses more energy (and fat) at rest. Hormonal decline in men and women tends to cause a loss of muscle mass accompanied by a slower metabolism.^[3] One eats less, consumes less protein, and engages in less activity, all of which contribute to a lower muscle mass. A higher muscle mass and protein consumption increase one’s baseline metabolism, making it easier to burn fat for fuel. This is why exercising and building muscle is vital and become even more important with age.

Sleep Disruption

Your sleep patterns can affect weight gain in your mid-40s. Sleep disruption is known to dramatically impact one’s energy levels, causing one to feel tired, stiff, and less active. As most hormones are kept regular through circadian signaling (your body clock), inadequate sleep can disrupt the satiety and hunger-regulating hormones, such as ghrelin and leptin. This can make you feel hungrier and crave more unhealthy foods.^[4] Sleep disturbances are more pronounced for women transitioning through menopause, although hormonal changes can lower the quality of sleep in older men as well.

Stress

Chronic stress can trigger the release of the hormone cortisol, which can stimulate your appetite and promote fat storage in the abdominal area. Studies show that cortisol elevations are predictive of weight gain, going hand-in-hand with food cravings.^[5] Like sleep deprivation, stress can also lower your energy levels and motivation to exercise. Women may be more sensitive to hormonal fluctuations capable of increasing stress levels than men, yet stress management is important for anyone prone to it.

Sedentary Lifestyle

If you have a sedentary lifestyle, you are likely to use up less energy than you consume, which can lead to weight gain over time. Exercising and muscle-building encourages more mitochondria to be produced all over the body, which lends itself to generating more energy during activity and balancing out one’s energy requirements, expenditure and appetite.

Diet

If you have an unhealthy diet that is high in processed foods, added sugars, and trans-fats, you are likely to consume more energy substrates than you need. Moreover, an unbalanced diet would be deficient in other nutrients that facilitate optimal energy expenditure. This results in quick weight gain without proper nutrition and enough physical activity. Crash diets that promise swift weight loss can backfire by slowing down your metabolism, increasing fatigue and causing muscle loss. To manage your weight effectively, you need to adopt a balanced diet and practice mindful eating with portion control to avoid overeating or under-eating.

How to Manage Weight Gain During Your 40s

Now that you know the causes of weight gain in your 40s, you may wonder what you can do to combat it. Here are some strategies that can help you manage your weight effectively:

Have a Regular Exercise Routine

One of the most important strategies for managing weight gain in the mid-40s is to follow a regular exercise routine that includes both cardiovascular and strength-training exercises:

• Cardiovascular Exercises such as walking, running, cycling, swimming, or aerobics can help you burn calories, improve your heart health, and reduce your risk of chronic diseases.
• Strength-Training Exercises such as lifting weights, using resistance bands, or bodyweight exercises can help you build muscle mass, increase metabolism, and improve body composition.

Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity cardiovascular exercise per week and at least two sessions of strength-training exercise per week.

Eat a Balanced and Nutrient-Rich Diet

Another key strategy for managing weight gain in the mid-40s is to follow a balanced and nutrient-rich diet. Focus on whole foods, fruits, vegetables, lean proteins, healthy fats, and complex carbohydrates that nourish your muscles and organs. These foods help you to feel full for longer, provide essential vitamins and minerals, and support your overall health and well-being.

Other key dietary factors that can help to lower weight include:

• Avoiding or Limiting Processed Foods, such as added sugars, trans-fats, and refined carbohydrates. These tend to spike your blood sugar levels, increase your calorie intake, and promote weight gain.
• Mindful Eating and Portion Control also help. Pay attention to your hunger and fullness cues, eat slowly, savor each mouthful, and eat without distractions. You can cut down portion sizes by using smaller plates and bowls and by using increased nutrition to compensate for lower portion sizes.

Prioritize Sleep and Stress Reduction

A third strategy for managing weight gain in your mid-40s is to prioritize sleep and stress reduction. As mentioned earlier, lack of sleep and chronic stress can affect your hormones, appetite, mood, and energy levels, which can influence your weight gain. Therefore, you need to improve your sleep quality and manage your stress levels. Here are a few tips:

• Stress Management Techniques. You can lower stress by adopting stress-reducing techniques such as meditation, yoga, and breathing exercises. Engaging in relaxing hobbies or socializing also goes a long way toward minimizing stress. These activities can help you to keep an optimal hormonal balance, regulate your appetite, improve your mood, and boost your energy levels.
• Practicing Good Sleep Hygiene. Sleep quality can be enhanced by following a regular sleep schedule, avoiding caffeine and alcohol before bed, creating a comfortable sleeping environment, and relaxing before bedtime.

Seek Out Professional Guidance

Finally, if you are struggling with weight gain in your mid-40s and need more help, you may want to seek professional guidance from a qualified healthcare practitioner. They will assess your medical history, current health status, lifestyle habits, and personal goals to understand why you are struggling. You can benefit from their personalized advice, support, and resources, which can help you to achieve your desired weight. They will also monitor your progress and adjust your plan as needed for the best results.

Conclusion

Weight gain in one’s mid-40s is a common phenomenon caused by various factors, most of which arise from hormonal changes. By understanding these causes and implementing the strategies discussed above, you can combat weight gain in your mid-40s successfully. By doing so, you will also improve your overall health and quality of life. Remember that weight management is not a one-time event but a lifelong process that requires a holistic approach and consistent effort.
