Saturday 28th January, 10,000 steps, no other activities = 316 active calories = 31.6 cal/1000 steps
Tuesday 31st January, 6291 steps, no other activities = 86 active calories = 13.6 cal/1000 steps
I usually hit my steps goal (10,000) and the calorie burn is consistently the same/similar. Suddenly it has halved.
Weight has not changed.
Why the difference?
