This year I've started the process of going from an Obese Runner to a Healthy Weight runner. In another month or two i'll have dropped 60 pounds bringing me under my upper range of healthy weight. I currently run over 20 miles a week. I've lost the weight with MFP set to sedentary and wearing one of my garmins (vivosmart 4 day to day, fenix 5s for runs) to estimate all day HR and calories burned. I only really ate back some calories earned on long run days. When switching to maintenance I wont be slowing down my activity as I have 2 marathons in January and March of 2020.
Garmin runners in maintenance how are you approaching your intake? Eat maintenance + 75% active calories? "How accurate are these things" I guess is my main question.
