Dynamic bounds doesn't mean no boundary. Maybe we viewed different communities, but I rarely came across people who thought calorie counting was 100% accurate.

Dynamic bounds doesn't mean no boundary. Maybe we viewed different communities, but I rarely came across people who thought calorie counting was 100% accurate. Human bodies are complex systems. But, calories in is still an upper bound, and calories out is still roughly accurate when tracking exercise. The big contention is the middle part.
