Standard definitions consider a healthy body mass index (BMI), a calculation based on a person's height and weight, as between 18.5 and 24.9. Studies have found that a higher BMI increases risk for heart disease, diabetes, and some types of cancer. However, even if their BMI does not fall into the category of overweight, people who gain five or more pounds may be at risk for health problems, especially if the weight gain is belly fat. The best approach is a combination of aerobic exercise, strength training, and a healthy diet.

Like the rest of the body, the feet are vulnerable to the effects of aging. Women may be more susceptible to certain foot conditions due to hormone fluctuations during pregnancy and a higher incidence of decreased bone density with aging. But everyone's soft tissues become less elastic, making foot problems more likely. Foot conditions that can develop or worsen with age include stress fractures, plantar fasciitis, bunions, flat feet, and osteoarthritis. Simple measures, such as resting the feet and wearing supportive shoes, can help ease pain.

Every bodily function relies on protein. People's protein needs are based on age, body size, activity levels, and overall health. Harvard experts advise people to consume between 1.2 and 2.0 grams of protein each day for every kilogram (2.2 pounds) of body weight. Women need more protein at certain times, including pregnancy and breastfeeding. People who are competitive athletes or trying to build muscle should also eat higher amounts of protein. Older adults should consume higher amounts to combat age-related muscle loss.

Psoriasis causes skin cells to multiply far faster than normal, leading to scaly, itchy, painful skin plaques. While treatments have vastly expanded, stigma surrounding psoriasis persists. Skin lesions can affect what people wear, what they do, and how they relate to others. To better cope, people with psoriasis can get family members involved in care and treatment decisions, see a dermatologist for more advanced therapies, revisit which treatments may work for them, and connect with others with the disease.

Viewing a solar eclipse can damage eyesight if eyes aren't protected. It can lead to solar retinopathy, with symptoms such as blurry or distorted vision, blind spots, and headaches. People planning to view a solar eclipse can wear special glasses to protect their eyes.

The ketogenic diet deprives the body of carbohydrates for fuel. Instead, the body uses ketone bodies, a type of fuel that the liver produces from stored fat. Keto diet followers must eat fat at each meal. In a daily 2,000-calorie diet, that might look like 165 grams of fat, 40 grams of carbs, and 75 grams of protein. Ditching carbs means limiting fruits and vegetables, which raises the risk for nutrient deficiencies. The keto diet also increases the risk for kidney, liver, mood, and thinking problems.

When a study asked doctors and artificial intelligence to respond to selected patient questions, a chatbot received higher ratings for empathy and quality. But a closer look at the research spotlights important limitations and findings.

Intrusive thoughts are unwanted thoughts or mental images that make people feel uncomfortable. They're common, affecting some six million Americans and can be effectively managed using tools such as cognitive behavioral therapy. They can be associated with mental health disorders such as obsessive-compulsive disorder or post-traumatic stress disorder, but many people who experience them don't meet the criteria for a mental health disorder. The thoughts may be triggered by stress or anxiety.

Though the visceral fat that lies behind the abdominal wall makes up only a small percentage of the body's fat, a growing body of research indicates that it is linked to a number of diseases and conditions.
