My estimate is coming from a research done 15-20 years ago and implemented in a calculator[1]. It is not precise but works well enough based on my personal history of walking more to lose extra weight. I switched to weight lifting, walking a lot and some kettlebell training for weight control after running for many years. Running is great but in my case resulted in joint and back problems. One surprising thing about walking vs running is that running doesn't burn all that much calories compared to the effort it requires. While I can integrate walking into my daily routine (15-30 minutes in the morning, at lunch time and in the evening), running needs at least 1.5-2 hours per day.
