Body mass index (BMI) uses weight and height to calculate whether a person is overweight or obese. However, it cannot determine the amount of visceral fat that lies deep inside the body. Two better methods are measuring waist size and determining waist-to-hip ratio.

During midlife and later, men often experience a lower energy level, sour mood, and decline in sex drive. These changes have been tagged with the term "male menopause." A low testosterone level may be a factor. Lifestyle changes, such as losing weight, increasing exercise, and following healthy sleep patterns, can help raise low levels. Another option is testosterone replacement therapy, but men need to weigh the possible benefits versus the risks.

Some people may feel like it's pointless to exercise if they're not losing weight as a result. But there are many reasons to exercise beyond weight loss. Regular exercise has a long list of health benefits, including an energy boost, better sleep, and reduced risks for addictive behaviors as well as many chronic diseases such as heart disease, strokes, many cancers, dementia (including Alzheimer's disease), diabetes, depression, anxiety, pneumonia, osteoporosis, and kidney problems.

In a 2024 study of more than 183,000 middle-aged healthy people followed for 13 years, those who closely followed a plant-based diet had lower risks of developing blood clots in the legs or lungs, even if their genes made them more likely to get the blood clots.

Anorexia of aging affects about one-quarter of older adults, and women more often than men. The condition is marked by diminished appetite and can prompt a breakdown of muscle and bone mass that can lead to frailty, falls, delayed recovery from illness or surgery, and earlier death. Risk factors include changes in smell and taste, swallowing problems, slower digestion, medications that lead to dry mouth, dental problems, cognitive decline, and loneliness or social isolation. Treatments can include exercising, boosting protein intake, and medications.

A 2024 research review suggested that drinking more water can help people stave off a variety of health problems as well as promote weight loss.

The FDA has approved three GLP-1 receptor agonist drugs for weight loss. The drugs not only lower blood sugar and weight, but also quiet inflammation, stimulate the production of antioxidants, help repair damaged DNA, and slow the aging of the body's cells. Evidence suggests that among people who use the drugs for diabetes and obesity, the drugs reduce the risks of kidney disease progression, heart attack, death from heart disease, death from COVID-19, and death from all causes by 15% to 35%.

Intermittent fasting is a weight-loss approach that involves not eating for a designated amount of time over the course of the day. One popular approach is called 16/8. Here, people eat during an eight-hour period followed by 16 hours of fasting. Intermittent fasting is often used to help with weight loss by placing the body in short-term ketosis, where the body burns fat for energy. While the supporting research is mixed, there's not much downside to trying intermittent fasting, and it also may help people manage their eating habits.
