💡 Only a few factors truly matter
- Out of 300+ studied, only about 30 lifestyle and biological factors consistently show strong effects on life expectancy.
- Most online “longevity advice” comes from commercial sources promoting supplements or unproven routines.
- Focus on what’s validated by long-term, peer-reviewed research — not marketing.
😴 Prioritize sleep
- When you deprioritize sleep, everything that can go wrong, eventually does: your blood pressure rises, your metabolism slows, your immune system weakens, and your focus fades.
- Aim for 7–8 hours of quality sleep — go to bed and wake up at consistent times, and protect your evenings from screens and stress.
🏃 Move every day
- Daily movement is one of the most powerful and accessible ways to protect your health.
- Walk more - benefits begin at around 4,000 steps per day, and even small increases can make a meaningful difference.
- Consistency matters most. Find ways to enjoy movement — listen to an audiobook, walk with a friend, or get a dog.
🩸 Manage cholesterol wisely
- About 80% of cholesterol is produced internally by your liver and intestines; only a small share comes from food. That means genetics, inflammation, and metabolism matter more than diet alone.
- Use lifestyle to support your heart — and follow medical advice when medication is needed.
💊 Stop random supplementing
- True nutrient deficiencies are rare in developed countries.
- Instead, focus on a balanced, diverse diet filled with vegetables, fruits, whole grains, legumes, nuts, and fish.
- If you take supplements, choose only those backed by solid clinical evidence and measurable results — not marketing claims.

BMI calculator
The evidence clearly demonstrates a non-linear relationship between BMI and mortality, with both insufficient and excessive body weight associated with increased mortality risk and reduced life expectancy.
