Vitamin D supplements have been growing in popularity, but they're not always needed or taken in the correct doses.

There are a number of steps to take when starting an anti-inflammation diet, such as the Mediterranean diet. The steps boil down to some dos and don'ts. For example, don't eat processed foods such as microwaveable dinners, hot dogs, white bread, dehydrated soups, baked goods, sugary cereals, processed meats, biscuits, and sauces. But do eat a diet of whole, unprocessed foods such as fruits, vegetables, whole grains, legumes (beans, lentils), fish, poultry, nuts, seeds, a little bit of low-fat dairy, olive oil, spices, and herbs.

Intermittent fasting-a diet that focuses on when rather than what a person eats-may be a good way to lose weight and improve cardiovascular health. One version, time-restricted feeding, involves eating only during a certain time window (usually eight hours) over a single day; another approach limits a person to just 400 to 600 calories daily for several days over the course of a week. The diet may reduce risk factors linked to heart disease, including type 2 diabetes, high blood pressure, unhealthy blood lipid levels, and inflammation.

Protein powder supplements can harbor health risks. They're recommended only for certain conditions, such as impaired appetite or wounds that are resistant to healing.

A 2026 review of six studies found that people with diabetes or obesity taking GLP-1 medications were prone to developing a number of nutrient deficiencies, particularly in vitamin D, iron, and B vitamins.

A plant-forward, varied diet can help people manage gout. Other helpful steps are to lose weight if needed, stay hydrated, avoid overeating and excessive alcohol, and take medications as prescribed. Small, sustainable changes can mean fewer flares and better quality of life.

Appetite tends to decline with age, but this can lead to unwanted weight loss and frailty. Tips to boost a weak appetite include eating smaller, more frequent meals; prioritizing protein; staying active; making meals social and pleasurable; and relaxing overly strict dietary rules.

People on a weight-loss regimen should aim to lose 1 to 2 pounds per week, which translates into eating 500 to 750 fewer calories each day than they expend. Losing weight faster often causes excess muscle loss and lowers metabolism, making it harder to burn fat.
