I made 10,411 steps. I have burned 472 calories. This makes for a target of 2,562. I have consumed 2,542 calories. So I met my target. Now let’s see what happens over the next several days. Do I gain weight, remain the same, or lose weight. IOW how accurate is my watch on calories burned? I have my calorie count for food being close to being accurate. If like other watches, it will be at least 20% off too high, or much more.

@UpDownAround, when you walk 12,000 and sometimes many many more steps that you sometimes make, you have to be burning a significant amount of calories. 12,000 steps for me is basically 5.5 miles. In the past, I think you registered 20,000 steps, correct? 20,000 steps for me is about 9 miles. As a rule of thumb, count 100 calories for each mile. This is not completely accurate. My watch gives me 105 to 115 calories per mile, with a couple times more, and a couple times below 100. Notice this is usually still above 100 calories per mile. So I think 100 is perhaps good enough to see if your watch is in the ballpark. Also when you halve the number of calories, this would mean you are burning 50 calories per mile. I think this is much too low. Oh yes, I just remembered that you use strava to calculate the distance. This makes it easier.

Otherwise, check to see if your steps on your watch is accurate. You know, walking around with you counting off the steps. Walk let’s say 500 steps. As you know, it should match your watch. Use google maps to determine the set of roads that are at a known distance, preferrably about a mile. Then walk that distance with your normal stride allowing your watch to count the steps taken. Do some math to give you a result for one mile. Then in the future, you can convert you steps to the number of miles. This is where the 100 calories per mile can be applied to check the accuracy of your calories burned given by your watch.

I have calibrated my watch this way to determine the accuracy of steps and the distance given by my GPS. They are both pretty close except for the occasional hiccup. Even then, it still provides only about a 10% or less error. This amount is the norm for many fitness watches, some even worse, except for the better more expensive watches. My error rate on steps and distance are normally about 3 to 5 percent, 3 percent frequently being the norm for me. BTW my normal stride is about 2.5 feet per step. I have gone as high as 3 feet per step.

Just my suggestion to you FWIW I do think you are doing great.

PS I need something like SUP to exercise my upper body. Maybe the weight machines at my gym can work out. But how can my watch calculate the calories burned from this? There are some exercises where the watch can, and others that it cannot. I have to find the machines that do work with the watch.
