16 different types of cancer linked to obesity. Some types of fat secrete more substances that promote cancer growth.
“For example, white adipose tissue has been associated with inflammation, and in breast cancer patients, has been associated with worse prognosis. Fat exists both under the skin and deeper inside the body surrounding internal organs (called visceral fat).”
Excess body fat reduces semen quality, potentially contributing to infertility.
“A recent review and meta-analysis found that men with obesity had lower semen volume, sperm number, and motility and fewer normal-shaped sperm than men with healthy body weight. The reviewers analyzed the findings of studies investigating links between body mass index (BMI) and semen quality.”
Brown fat is linked with lower risk of some chronic diseases.
“Obesity, or having excess body fat, is a known risk factor for a wide range of diseases, including diabetes, cancer, and dementia. Findings from a new study indicate that having brown fat is linked with lower risk of some chronic diseases.”
Intermittent fasting improves cardiometabolic health.
“People who have cardiometabolic syndrome are more likely to die from heart disease or experience a heart attack or stroke than those without the syndrome. Findings presented in a recent review suggest that intermittent fasting improves aspects of cardiometabolic health in people who have obesity.”
Environmental enrichment alone produces browning of fat and enhanced weight control not accountable by exercise alone [animal study]
“> • Fed a high fat diet (45 percent fat), enriched animals gained 29 percent less weight than control mice and remained lean, with no change in food intake. Enriched animals also had a higher body temperature, suggesting that greater energy output, not suppressed appetite, led to the resistance to obesity.”
Beige fat protects against dementia by reducing visceral-like properties of subcutaneous fat
“It is stored in the abdominal cavity close to internal organs such as the liver, pancreas, and intestines. An excess of visceral fat, often referred to as central obesity or abdominal obesity, is commonly associated with an "apple" shape and an increased risk for chronic disease, including dementia.”

The Biology of Breast Milk
“Consequently, the risk of developing metabolic and cardiovascular diseases such as obesity, diabetes, and hypertension in childhood – as well as later in life – is likely determined by early feeding and nutritional status.”
Around 1 in 5 women have Polycystic Ovary Syndrome (PCOS) and new research shows young women with it up to 5x more likely to develop type 2 diabetes.
“"Crucially, obesity, a key trigger for type 2 diabetes, was not an important trigger in women with PCOS.". Often PCOS is undiagnosed. Symptoms can include irregular periods, weight gain, excessive facial hair and acne.”
A combined aerobic-resistance training regimen proves equally effective for cardiovascular health as aerobic alone.
“Researchers conducted a randomized controlled trial involving 406 adults with overweight or obesity and elevated blood pressure. They randomly assigned participants to one of four exercise intervention groups: aerobic only, resistance only, a combination of aerobic and resistance, or no exercise.”
