This study tests whether eating a sustainable diet, like the Planetary Health Diet or a vegetarian diet, can improve heart health in adults aged 45-70 who are at risk for heart disease. Researchers will measure changes in blood pressure, cholesterol, blood sugar, and other marker…

This study tests whether adding about 45 minutes of sleep each night can help school-aged children (6-12 years) who are overweight and sleep less than 9 hours. Over 3 months, one group will go to bed earlier while the other continues their usual routine. Researchers will measure …

This study is testing whether a simple vision screening done in a regular doctor's office can help find vision problems early in people over 70 who have at least one chronic condition like diabetes or high blood pressure. About 460 participants will be invited to take vision test…

This study looks at how taking a high dose of biotin (vitamin B7) can temporarily mess up certain blood tests. Researchers will give 24 healthy adults either biotin or a placebo and then check their blood for changes, especially in thyroid antibody levels. The goal is to understa…

This study is testing whether combining fasting with regular exercise can slow the aging process in people over 65. Researchers will measure biological age using DNA markers and other health indicators over one year. 240 participants will be split into four groups: exercise only,…

This study looks at how medium-chain and long-chain fatty acids affect metabolism in people with MCADD (a rare genetic disorder) and healthy volunteers. Researchers will measure ketone bodies and resting metabolic rate after fat intake. The goal is to better understand the body's…

This study looks at how calcium and phosphorus from food affect people with advanced chronic kidney disease (stages 4 and 5). Researchers will compare two ways of tracking what patients eat—taking photos of meals versus writing down everything—to see which works better. The goal …

This study looks at how two short-chain fatty acids—propionate and butyrate—affect the body's metabolism in healthy adults. Ten volunteers will take each fatty acid on separate visits, and researchers will measure changes in ketones, glucose, and other markers. The goal is to und…

This study looks at how a single bout of exercise improves the way muscles respond to insulin in healthy young men. Researchers will have participants do a one-legged knee exercise and then measure insulin sensitivity using a special clamp technique. The goal is to understand the…

This study looks at how exercise training changes muscle cells in adults with mitochondrial myopathy, a disease that affects energy production in muscles. Researchers will compare a trained leg to an untrained leg in the same person, and also compare people with the disease to he…
