LIFE1 Guides

• Zone 2 training: what it is and how to find your range
  Zone 2 is steady, conversational effort. What it is, why endurance coaches use it, how people find their range without a lab, and how LIFE1 shows your heart rate during a session.
• Intermittent fasting windows: 16:8, 14:10 and what the research says
  The common time-restricted eating windows, what trials have found when fasting is compared with ordinary calorie restriction, and how LIFE1’s fasting timer works.
• How much protein for weight loss and muscle: what the evidence says
  How much protein the research supports for keeping or building muscle, why it matters more during weight loss, and how LIFE1 scores each meal against your protocol.
• HRV explained: what heart rate variability is, and what it is not
  Heart rate variability in plain terms: what the number measures, why it differs so much between people, what tends to move it, and how LIFE1 shows it without interpreting it.
• Resting heart rate: what changes it and how to read your own trend
  What resting heart rate is, the range public health bodies describe, what moves it up or down, and how LIFE1 draws it as recorded.
• What the LIFE1 Health Score is, and what it is not
  How the LIFE1 Health Score is built from your meals, training, readings and wearable data, what moves it, and why it is not a diagnosis or a medical assessment.

LIFE1 shows what you measured and what published guidelines say. It does not diagnose, interpret or treat. This page is general information, not medical advice.
