As the golden hues of dawn break the night’s silence, many of us in our middle years find ourselves caught in a silent struggle. The vigor of youth seems a distant memory, and the mirror reflects a story of life’s wear and tear. But there is a powerful ally in our quest for vitality and health: quality sleep. It’s the unsung hero that can redefine our fitness journey, especially as we navigate the complexities of middle age.

The Science of Sleep and Metabolism


Sleep is a critical component of our overall health, intricately linked to our metabolic processes. During the deep stages of sleep, our bodies engage in various functions, including muscle repair and growth hormone release, which are vital for fat loss and overall fitness. On the flip side, sleep deprivation can lead to hormonal imbalances, increased appetite, and weight gain, undermining our fitness goals.

Esté Bell is a holistic health and nutrition coach with a specific interest in sleep, stress and recovery management. As a teenager she developed disordered eating habits, followed by a diagnosis with Polycystic Ovarian Syndrome a couple of years later. The resulting health and weight management issues led to a passion for holistic nutrition and the desire to help others transform their health. It was during her marriage to an emotional-abusive alcoholic that she personally experienced the importance of sleep, and stress and recovery management. She is the CEO of LevelUp Nutrition, based in South Africa, and has dedicated her life to encourage, equip and empower her clients to make change happen.
