Two Diets Linked to Improved Cognition, Slowed Brain Aging

An intermittent fasting (IF) diet and a standard healthy living (HL) diet focused on healthy foods both lead to weight loss, reduced insulin resistance (IR), and slowed brain aging in older overweight adults with IR, new research showed. However, neither diet has an effect on Alzheimer's disease (AD) biomarkers.

Although investigators found both diets were beneficial, some outcomes were more robust with the IF diet.

Larry Williams adds:

A “dry” fast loses weight more than wet fast.

Sergei's AI says:

The main difference between dry fasting and wet fasting, also known as water fasting, is whether you consume liquids:

Dry fasting: Restricts both food and liquids, including water, broth, and tea. It can be done as part of intermittent fasting, which cycles between eating and fasting. For example, you might restrict food for 16 hours and eat during an 8-hour window. Wet fasting: Allows you to drink water, and sometimes certain teas.

Dry fasting can be dangerous, especially for long periods of time. Some potential side effects include: Dehydration, Nutrient deficiencies, Urinary problems, Kidney issues, Heat injury, and Swollen or ruptured cells.

    Study design is always a challenge and can bias findings. Poor glucose metabolism contributes to AD. Ketones provide better brain energy. Alternate 2022 study: “The brain relies on glucose as its primary source of energy, but in people diagnosed with Alzheimer’s disease (AD), the brain is less able to use glucose for fuel. Researchers at the University of Kansas, an NCATS Clinical and Translational Science Awards (CTSA) Program hub, recently explored the potential of another source of energy—ketones—to improve brain function in people with AD. Ketones are produced when glucose is in short supply and the body turns to fat as its main energy source. Although the brain’s ability to use glucose declines in AD, its ability to use ketones does not.” https://ncats.nih.gov/news-events/news/ketogenic-diet-alzheimers
