Goal: build a few simple habits you can sustain. Focus areas: diet, movement, sleep. Keep it easy and consistent.

Week 1 – Reset the basics
Diet

  • Drink a full glass of water after waking and before each meal.
  • Add one fruit or vegetable to every meal.
  • Reduce sugary drinks; replace with water or unsweetened tea.

Exercise

  • Walk 10–15 minutes daily.
  • Do 5 minutes of light mobility (neck rolls, shoulder circles, gentle squats).

Sleep

  • Pick a consistent bedtime and wake time (within ~30 min daily).
  • Stop screens 30 minutes before bed.
  • Get morning sunlight for 5–10 minutes.

Week 2 – Build consistency
Diet

  • Aim for balanced meals: protein + fiber + healthy fat.
  • Example: eggs + fruit, chicken salad, beans and rice with vegetables.
  • Avoid heavy late-night snacking.

Exercise

  • Walk 20 minutes 5 days this week.
  • Add 2 short strength sessions:
    • 2 sets each: squats, push-ups (wall or knee), plank (20 sec).

Sleep

  • Keep the same sleep schedule.
  • Avoid caffeine within 8 hours of bedtime.
  • Dim lights in the evening.

Week 3 – Improve quality
Diet

  • Make half your plate vegetables at one meal per day.
  • Eat protein at every meal (eggs, yogurt, beans, fish, tofu, chicken).
  • Limit ultra-processed snacks to once per day max.

Exercise

  • 25–30 minutes walking or light cardio 5 days/week.
  • Strength training 3 days/week:
    • squats
    • push-ups
    • glute bridges
    • plank
      (2–3 sets each)

Sleep

  • Create a 10-minute wind-down routine (stretching, reading, breathing).
  • Keep bedroom cool, dark, quiet.

Week 4 – Lock in habits
Diet

  • Cook at home at least 4–5 days this week.
  • Focus on whole foods: vegetables, fruits, legumes, whole grains, lean proteins.
  • Stay hydrated (roughly 6–8 glasses water daily).

Exercise

  • 30 minutes of movement most days (walking, cycling, light jogging).
  • Strength training 3 times/week.
  • Try one longer activity on the weekend (45–60 minute walk, hike, bike).

Sleep

  • Protect your sleep window (7–9 hours).
  • Keep phones out of reach at night if possible.
  • Review what helps you sleep best and stick with it.

Simple daily checklist

  • Move your body
  • Eat whole foods + vegetables
  • Drink water
  • Get sunlight
  • Sleep 7–9 hours

If followed consistently for a month, these habits create a strong foundation for long-term health and longevity.
