The Shocking Link Between Testosterone, Weight Gain, and Heart Disease

What Is Testosterone?

Testosterone is a steroid hormone produced in the testes in men and the ovaries and adrenal glands in women. Men typically have levels 10-20 times higher than women, but the hormone is vital for both sexes (Nassar & Leslie, 2021).

It regulates key functions, including:

• Muscle and bone health
• Mood and energy levels
• Metabolises carbohydrates, fats and proteins
• Sex drive and fertility
• Red blood cell production

Testosterone also plays a key role in carbohydrate, fat and protein metabolism and has a major influence on body fat composition and muscle mass in the male.
For women, testosterone also influences ovarian function, sexual arousal, and overall wellbeing (Burger, 2002).

Why Is Testosterone Important?

Of all the androgens involved in regulating and maintaining body composition, testosterone is arguably the most well-known and significant, as it is closely linked to various health conditions, including metabolic syndrome, type 2 diabetes, and cardiovascular disease. (Kang H Y, 2013)

Testosterone is essential for overall health in both sexes. Proper levels support:

• Cognitive function: Testosterone influences memory and focus, with lower levels linked to cognitive decline in ageing men and women (Carson & Rosano, 2012).
• Heart health: Balanced testosterone levels correlate with improved cardiovascular function, although extremes—too low or too high—can be harmful (Vigen et al., 2013).
• Metabolic health: Testosterone regulates fat distribution and energy production, impacting obesity and diabetes risk (Kelly & Jones, 2013).

What Happens When Testosterone Levels Are Imbalanced?

Testosterone deficiency is linked to increased fat mass, particularly central adiposity, along with reduced insulin sensitivity, impaired glucose tolerance, elevated triglycerides, and cholesterol, as well as low HDL cholesterol. These features are commonly associated with metabolic syndrome (MetS) and type 2 diabetes, both of which contribute to cardiovascular risk. 

Clinical trials have shown that testosterone replacement therapy can improve insulin resistance and glycaemic control in these conditions. It also helps reduce overall body fat, particularly truncal adiposity, while lowering cholesterol and triglyceride levels.(Kelly & Jones, 2013).
 

Testosterone Imbalance In Men

• Low testosterone (hypogonadism): Symptoms include fatigue, depression, reduced muscle mass, erectile dysfunction, low libido, infertility, and osteoporosis (Bhasin et al., 2018). Untreated, it can impair cardiovascular health and increase the risk of metabolic syndrome.
• High testosterone: Rare but possible, especially due to supplementation or certain medical conditions. It may lead to aggression, high blood pressure, acne, low sperm count or infertility, and an increased risk of cardiovascular events (Basaria et al., 2010).

High testosterone in males, also known as hypergonadism, can be caused by a number of underlying health and medical conditions, including:

• Benign and malignant tumors in the testicles
• Infections
• Kidney and liver problems
• Autoimmune disorders
• Genetic abnormalities
• Injury
   

Testosterone Imbalance In Women

• Low testosterone: Women with insufficient testosterone may experience reduced libido, fatigue, poor concentration, and muscle weakness. These symptoms are especially common during menopause (Davison et al., 2005).
• High testosterone: Commonly associated with polycystic ovary syndrome (PCOS), symptoms include irregular periods, acne, excess hair growth, and increased risk of insulin resistance and type 2 diabetes (Azziz et al., 2004).

How to Increase Testosterone Naturally

Low testosterone is increasingly common due to stress, poor diet, and sedentary lifestyles. Here’s how to boost levels based on research:

Diet

• Zinc-rich foods: Zinc is critical for testosterone production. Foods like oysters, lean meat, and seeds improve levels (Prasad, 2013).
• Healthy fats: Dietary fat intake, particularly monounsaturated fats, is linked to increased testosterone levels (Volek et al., 2001). Sources include avocados, nuts, and olive oil.
• Vitamin D: Supplementing vitamin D3 increases testosterone in deficient individuals (Pilz et al., 2011).
• Magnesium: Magnesium enhances testosterone levels, particularly in physically active individuals (Cinar et al., 2011).
• High-quality proteins: Protein sources like eggs, chicken, and fish are essential for muscle repair and hormone synthesis.

Exercise

• Strength training: Lifting weights or performing resistance exercises boosts testosterone, especially when engaging large muscle groups (West et al., 2011).
• High-intensity interval training (HIIT): Short bursts of intense exercise increase testosterone more than steady-state cardio (Hackney, 2006).
• Reduce sedentary time: Prolonged sitting is associated with lower testosterone levels (Aldred et al., 2009).

How to Lower Testosterone Naturally

For women with conditions like PCOS, lowering testosterone can alleviate symptoms. Lifestyle changes supported by science include:

Diet

• Low-glycaemic index foods: These stabilise blood sugar, reducing insulin spikes that drive excessive testosterone production (Barber et al., 2006).
• Anti-inflammatory foods: Turmeric, ginger, and omega-3 fatty acids lower systemic inflammation, indirectly helping balance hormones (Calder, 2006).
• Limit sugar and processed carbs: Excess sugar can worsen insulin resistance and exacerbate hormonal imbalances (Paoli et al., 2013).

Exercise

• Cardiovascular workouts: Aerobic exercise improves insulin sensitivity and reduces androgen levels in women with PCOS (Harrison et al., 2011).
• Yoga or pilates: Stress reduction through mindful exercise helps lower cortisol, which indirectly regulates testosterone (de Sousa et al., 2015).
