  2. In a bowl, toss the apple slices with brown sugar, flour, cinnamon and nutmeg until coated.
  3. Pour melted butter over apple mixture and stir to coat apples.
  4. Roll out pie crust and press into a 9-inch pie plate. Scoop apple mixture into pie crust.
  5. Bake for 25-30 minutes, until apples are tender and top is lightly browned.
  6. Allow to cool 15 minutes before serving.

Claude 2Beginner's Longevity Plan
claude-2 logo
Claude 2

Here is a 1-month beginner health and longevity plan focused on diet, exercise, and sleep:

Diet:

  • Eliminate sugary drinks and limit sweets. Replace with water and fruits.
  • Eat more veggies. Aim for 1-2 cups with each meal. Focus on dark leafy greens, broccoli, carrots.
  • Increase fiber intake. Eat beans, lentils, oats, berries, and nuts.
  • Cook at home more instead of eating out.

Exercise:

  • Walk for 30+ minutes, 4-5 days per week. Start slow if needed and gradually in crease pace and distance. Go ing outside is great motivation! - Do bodyweight exercises like squats, lunges and pu shups 2-3 times per week. Start with 5-10 reps, 2 sets. Build up gradually. Can be done at home with no equipment.

Sleep:

  • Stick to a regular sleep/wake time schedule, even on weekends.
  • Develop an relaxing pre-bed routine - hot bath, read a book (not a screen), un wind.
  • Make your bedroom dark, quiet, and cooler temperature. Remove screens and dist racting devices.
  • Try to get 7-8 hours a night. Nap if excessively tired but limit to 30 minutes .

The key is developing sustainable habits. Start with small, realistic changes fo cused on nutrient-dense whol e foods, more activity in your day, and consistent restful sleep. Monitor energy and how you feel to track progress. Be patient, stay positive, and congratulate small wins. After a month reevaluate and build upon what's working. The journey continues by adding more longevity boosting practices around stress management, connections with others, and finding purpose. But this is an excellent healthy foundation to start with!
