Several factors may cause testosterone levels to drop

A 2023 analysis suggests that men older than age 70 can fight declining testosterone levels by engaging more in healthy lifestyle behaviors like increasing exercise, losing weight, and managing high blood pressure.

Early morning exercise may be the best time for weight loss

A 2023 study found that people who exercise in the morning, specifically between 7 a.m. and 9 a.m., have a lower risk of obesity than those who are most active in the midday or evening.

Can weight loss slow prostate cancer?

Many men diagnosed with low-grade prostate cancer follow active surveillance, in which they regularly follow up with a doctor for routine PSA tests, prostate biopsies, and possibly MRI scans. If there is evidence their cancer has progressed, then they can consider treatment (radiation or surgery). While there is little men can do to slow the growth of known low-grade prostate cancer, losing excess weight and keeping it off may help keep undetected high- or medium-grade cancer from becoming more aggressive.

Beyond appetite suppression

Semaglutide (Ozempic, Wegovy), which mimics a natural hormone called GLP-1, has become a popular obesity drug because it promotes dramatic weight loss. New evidence suggests this drug and others like it may also curb compulsions for things other than food. The drugs may also dampen cravings for alcohol, smoking, gambling, and excessive shopping by hampering activation of the brain's reward pathways. If further research confirms preliminary findings, the demand for GLP-1 drugs is likely to increase.

Understanding new weight-loss drugs

A newer class of medications used to treat type 2 diabetes called glucagon-like peptide-1 (GLP-1) receptor agonists has gained attention because of their impressive weight-loss results—in many cases, 10% to 20% of a person's body weight. Versions of two of these GLP-1 receptor agonists, liraglutide (Saxenda) and semaglutide (Wegovy), are FDA-approved for weight loss, even for people without diabetes. However, there isn't enough evidence to know whether these drugs might be beneficial or dangerous for people who are not diagnosed with diabetes or obesity.

Debunking common wellness myths

Many common wellness myths contain a grain of truth but are misleading over all. One wellness myth holds that being thin equates to being healthy, but people who are think can still be unhealthy. Another myth posits that detoxes and cleanses can help people be healthier, but these products don't help and can even be dangerous for some people. Another myth is that eating before bedtime leads to weight gain, but food choice matters more than timing.

Hidden causes of weight gain

The reason for weight gain isn't always as obvious as inactivity or a poor diet. Weight gain can stem from many other causes. For example, it might reflect age-related physiological changes such as muscle loss, poor sleep, or changes in sex hormone levels; underlying conditions such as diabetes or sleep apnea; side effects from taking certain medications, such as antidepressants or beta blockers; or possibly the effects of eating late at night or the makeup of gut bacteria. Recent or excessive weight gain warrants a visit to a doctor to help pinpoint the issue.

An inside look at body fat

As men age, their metabolism naturally slows, and they burn calories more slowly. They can be less active and consume extra calories. The result is a buildup of visceral fat inside the abdominal cavity and around vital organs. This can raise heart disease risk factors, such as blood pressure, blood sugar, and total cholesterol levels. The best way to fight visceral fat is with aerobic exercise, strength training, and a healthy diet that includes plenty of protein.

Overcoming heart health obstacles

Men often confront obstacles that keep them from managing heart disease or lowering their risk for it. Harvard cardiologists share the advice they give patients who face challenges in the areas of weight loss, medication management, exercise, and diet. These include thinking about their future health goals, monitoring blood pressure, scheduling workouts, joining group weight-loss groups, and learning portion control for meals.
