NEW IRON FAMILY EPISODE: Why is it HARDER to lose weight in your 30s- 40s?!

On this episode of The Iron Family Podcast, we dive into one of the most overlooked barriers to fat loss and muscle growth—cortisol, also known as the stress hormone. If you’ve been struggling to lose weight, build muscle, or get quality sleep, cortisol might be the culprit.

Cortisol is released by the adrenal glands in response to stress, playing a key role in metabolism, blood sugar regulation, and inflammation.

However, when stress becomes chronic—due to busy work schedules, family responsibilities, and lack of sleep—cortisol levels can become dysregulated.

This often leads to fat storage (especially around the midsection), muscle breakdown, and sleep disturbances, including those frustrating 2 AM wake-ups.

In this episode, Theresa breaks down how high cortisol levels:

• Disrupt sleep by causing blood sugar crashes in the middle of the night.
• Lead to fat retention and muscle breakdown, making it harder to achieve fitness goals.
• Become more dominant in women going through perimenopause and post-menopause, as estrogen and progesterone levels decline.

So, what’s the solution?

Theresa emphasizes the importance of stress management, proper nutrition, and strength training over excessive cardio.

A well-balanced diet with enough protein, healthy fats, and slow-digesting carbs can help regulate cortisol levels, improve sleep, and support muscle growth.

Less is often more when it comes to exercise—prioritizing quality workouts over excessive training is key to long-term success.
