Welcome to part four of the 50,000 Mile Tuneup Series. In previous episodes, we checked into our beliefs and expectations about aging, updated our goals, and clarified our values and priorities. We then turned our attention to exercise and movement. 

Take aways:
- As we age, we need fewer calories and more protein. 
- Cutting back on starches and liquid calories can help lower caloric intake. 
- Splitting your protein intake up into 30g doses, spread over the day, can maximize the benefits.
- Don’t forget to include a great variety of fresh, whole foods in your diet on a regular basis.
