An unexpected social consequence of caloric restriction is that a very skinny face is often perceived as unhealthy, making it harder to convince others of your vitality.

You can treat your resting heart rate as an accountability partner to prevent late-night snacking by remembering that even one bite will raise it and disrupt your sleep.

To avoid negatively impacting your sleep, strenuous exercise should be completed at least four, and preferably six, hours before your bedtime.

If the only time you can possibly work out is right before bed, it is occasionally worth sacrificing sleep quality for the significant longevity benefits of high-intensity exercise.

One speaker's philosophy is that sleep should be prioritized above everything else in life, including family and work, because it is the fundamental fuel source for existence.

Resting heart rate before bed is arguably the single most important biomarker, as it reflects a combination of your diet, stress, vices, and cardiovascular fitness.

An extreme but effective protocol to lower resting heart rate involves eating your final meal of the day around noon, approximately eight and a half hours before sleep.

Even a single alcoholic beverage can increase an individual's resting heart rate by four to five beats per minute, which directly harms sleep quality.

A unique psychological technique to manage bad habits is to personify and name the version of yourself that wants to indulge (e.g., "Evening Brian") and then set strict rules for that persona.

For the best longevity outcomes, the data suggests you should target a resting heart rate of less than 65 beats per minute.
