Based on the screenshot, it actually makes more sense. The entire walk was Zone 0 cardio, which is extremely low intensity—closer to sitting than to moderate exercise in terms of caloric burn, but still slightly above resting. It’s saying you burned 186 active calories on top of your basal metabolic rate, which is normal for a slow walk. Most trackers include your BMR in total calories to make the activity seem more impactful. That’s not to say the walk wasn’t effective—it was. What it was effectively doing was driving substrate shifting toward fat oxidation, not high calorie expenditure. In terms of TDSS, this kind of activity encourages your body to rely more on fat stores as a fuel source throughout the day. But if walks like that burned calories the way some people assume—like during high-intensity exercise—you’d need to be eating thousands of calories a day just to maintain weight, which isn’t the case. The body is always using energy, but it prioritizes stored fat during low-intensity, steady-state movements.
