Obesity is linked with more than 50 illnesses and diseases including heart disease, cancer, diabetes, dementia, scores of others. Currently at least 33 percent of the world’s population is estimated to be overweight or obese, that estimate is likely to rise to 50 percent within a decade or so. Most overweight and obesity is believed linked with lifestyle: too little exercise; too many calories; fast, fatty, fried, and frozen food choices; sodas (regular or diet), lack of portion control, snacking between meals, eating refined and processed foods, and so on. It is critically important to keep your weight within a normal range for your gender size, and bone structure; and to avoid belly fat. Aromatase in fat cells (especially in belly fat) converts testosterone into estrogen, which creates an imbalance of hormonal levels and is undesirable for both males and females. Prevention strategy? Keep your weight within a desirable range for your gender, age, and size.
