Description

Estimate your biological fitness age based on metrics, lifestyle, and tests to compare with chronological age and get aging-slow tips.

Use Cases

Tracks aging rate.

Inputs/Variables Explained

We ask for chronological age, fitness test results, VO2 max, lifestyle habits, sleep quality, stress level, and smoking/alcohol because these estimate biological age. These inputs motivate longevity. Limitation: the tool uses estimates and may not reflect genetic factors; use as motivational guide, not medical diagnosis.

Key Metrics Explained

  1. Chronological Age: Your actual age (30-40).
  2. Fitness Level: "Good (Above Average)" indicates you engage in regular physical activity.
  3. Diet Quality: "Athletic / Clean Diet" suggests a strong focus on nutrition.
  4. Sleep Quality: "Average (6-7 hours)" reflects a moderate amount of rest, which is crucial for recovery and health.
  5. Activity Level: "Moderate" indicates regular but not excessively intense activity.
  6. Stress Management: "None" indicates a need for better stress management practices.

Recommendations for Slowing Biological Aging

1. Exercise

  • Strength Training: Incorporate 2-3 sessions per week focusing on major muscle groups. This helps maintain muscle mass and bone density.
  • Cardiovascular Exercise: Aim for 150 minutes of moderate aerobic activity per week, such as brisk walking or cycling.
  • Flexibility and Mobility: Include yoga or stretching exercises at least twice a week to improve flexibility and reduce injury risk.

2. Diet

  • Balanced Nutrition: Focus on whole foods, including:
    • Fruits and Vegetables: Aim for a variety of colors.
    • Lean Proteins: Include fish, poultry, legumes, and nuts.
    • Healthy Fats: Incorporate sources like avocados, olive oil, and fatty fish.
  • Hydration: Drink plenty of water throughout the day; aim for at least 8 cups.
  • Limit Processed Foods: Reduce intake of sugar, salt, and unhealthy fats.

3. Sleep Improvement

  • Quality Over Quantity: Aim for 7-9 hours of quality sleep per night.
  • Sleep Hygiene: Establish a consistent sleep schedule and create a restful environment (dark, cool, quiet).

4. Stress Management

  • Mindfulness and Meditation: Practice mindfulness or meditation for at least 10 minutes daily to reduce stress levels.
  • Physical Activity: Regular exercise is also a great way to manage stress.

Improvement Plan

  1. Weekly Schedule:
    • Monday: Strength training (upper body)
    • Tuesday: Cardio (30 minutes)

  2. Nutrition Goals:

    • Plan snacks that include fruits, nuts, or yogurt.
  3. Sleep Routine:
