At the age of 30, men often encounter notable physiological changes.
One prominent concern is the increased difficulty in losing abdominal fat, which coincides with a general decline in health during this period. A significant factor in these changes is the onset of natural muscle loss, or atrophy, which can lead to increased weakness.
The key and scientifically proven contributor is the fluctuation of male hormones, particularly androgens, with testosterone being the most significant!
Proven strong correlation between low testosterone, obesity and ageing
Research has established a well-documented relationship between declining testosterone levels, obesity, and the ageing process [1].
As men age (and are affected by the inevitable decline in testosterone levels), their body composition undergoes changes.
Various studies have revealed a strong correlation between low testosterone levels, ageing, and obesity [2], attributing to the vital role that androgens play in regulating body fat and its distribution.
With the decline in testosterone level, fat and weight tend to rise leading to higher body fat levels and reduced muscle mass, as muscle fibres diminish due to a decrease in muscle protein production in the body [3].
Hormonal Shifts after 30 That Affect Fat Loss
Hormonal shifts after the age of 30 can further complicate efforts to lose fat. Weight management will then become increasingly challenging, driven by a natural metabolic slowdown.
As men age, their bodies tend to retain more fat due to hormonal responses becoming less effective, resulting in altered signals within adipose tissue.
Hormones such as leptin, ghrelin, and adiponectin, which help regulate appetite and metabolism, are influenced by testosterone. This highlights the intricate interactions testosterone has with various organs, including the liver, adipose tissue, muscle, and heart.
Chronic Stress makes you fat, especially in the belly
Life begins at 30 for most men – as new fathers, husbands, and with career promotions… And with a new role in life, the level of responsibilities also increases, including the stress hormone, Mr Cortisol.
Those with a high waist-hip ratio tend to have higher cortisol levels in response to stress compared to those with a low waist-hip ratio.
Research has shown that both stress induction and the resulting stress responses, such as cortisol and blood pressure, can negatively impact performance on tasks like the Auditory Verbal Learning Test (AVLT) [4]. This impairment is even greater when these males specifically react to stress.
In obesity, more cortisol is produced from cortisone, which may be caused by an increase in visceral fat. High cortisol levels, combined with low levels of sex hormones (such as testosterone) and growth hormone, can lead to increased fat storage in the abdomen and metabolic issues [5].
Cortisol can also:
- Increase appetite and caloric intake
- Possibly causes leptin resistance (the hormone that tells us when we're full)
- Boost neuropeptide Y activity, which increases appetite
These effects may help explain "stress eating," though the exact reasons are still not fully understood.
You are not alone in this journey. There are pathways to reclaiming your vitality and confidence as you navigate this new chapter in life. And we are here at every step of the way.
