WHAT YOU CAN DO IN THE APP Overview See your biological age, aging rate, and key health metrics at a glance. Track your trajectory over time and know exactly where you stand.

THE SCIENCE Every protocol links to published research from journals including Nature Aging, Cell Metabolism, JAMA, and The Lancet. Recommendations are tiered by evidence quality so you always know what's well-proven versus emerging. IMPORTANT FixMyAge is an AI-powered health advisory and tracking service, not a medical practice.

Benefits of Fasting Intermittent fasting has grown popular for its potential health benefits. Here are some of the main benefits: • Weight Loss: Intermittent fasting creates a calorie deficit, helping reduce calorie intake and promote weight loss. • Better Metabolism: Fasting can improve insulin sensitivity, help regulate blood sugar levels and boost metabolism. • Cellular Repair: During fasting, the body triggers autophagy, clearing out damaged components and promoting cellular renewal. • Heart Health: Intermittent fasting helps improve several cardiovascular risk markers, including lowering blood pressure, reducing triglycerides and improving cholesterol levels. • Brain Health: Studies suggest intermittent fasting may support brain health and cognitive function, and may even protect against neurodegenerative diseases like Alzheimer's. • Reduced Inflammation: Fasting can ease inflammatory responses in the body, and chronic inflammation is linked to arthritis, some cancers and various other conditions. Please note that intermittent fasting is not for everyone. If you have an underlying condition, are pregnant or taking medication, consult a healthcare professional before starting. A balanced diet and healthy lifestyle are what maximize the benefits of fasting.
