The program for people who believe real health begins with natural solutions.
Find your body's natural rhythm
Discover the benefits of fasting and circadian rhythms for a longer, vibrant life
Science backed
Research has shown timing our daily eating, sleep, light, and exercise can impact health and performance. This program is part of the Ontime community developing habits to improve all aspects of health.
Lose weight
FAST. Start fasting smarter for 4x the benefits. Learn how timing our meals accelerates weight loss.
Sleep better
SLEEP. Research shows this method improves deep sleep, quality, and duration. In the past, we had no lights and devices to keep us up all hours. Better tools are here to rest our body naturally.
Stay fit
MOVE. Staying active and moving daily is totally free. Build a healthy habit of 30 minutes each day to help sleep, weight loss and longevity.
Track Light
LIGHT. Measure light twice a day to sync your body for health. The light and dark cycle of the sun drives health. Light controls melatonin, focus and our sleep.
Always backed by science

What’s fascinating about Dr Panda’s work is how it shows that our bodies are designed to operate on a certain rhythm, even down to when we eat. By syncing our eating patterns with our circadian rhythms, we can potentially tap into a lot of health benefits.
Andrew Huberman
This work has shown that intermittent fasting and time-restricted eating can help align our eating patterns with our natural circadian rhythms, which can improve metabolic health and reduce the risk of chronic diseases.

This research has hugely influenced the way that I practice medicine and what I do with my patients. I really passionately believe in living in harmony with your circadian body as much as you can. Frankly, there’s very few areas in your life that won’t improve.
Dr Palaniappan Manickam
Understanding the circadian rhythm’s importance is like knowing when to fuel a car for optimal performance—you wouldn’t fill it up when the engine’s off. Similarly, our bodies operate best when we eat in sync with our internal clock.
