Carefully counting calories can help those of us who have diabetes lose weight. But the discipline and effort involved in monitoring our calorie intake over a period of months or years is a lot of work, and few of us can keep it up for long. For this reason the average amount of weight that people lose typically slows down after a few months.
A huge proportion of people with diabetes need to lose weight. The percentage is far higher than that of the general population. For years before and after I learned in 1994 that I have diabetes, my own weight was far too high, and this probably had a lot to do with my getting diabetes in the first place and certainly made managing my diabetes a lot harder than it had to be.
Much easier and perhaps just as effective than counting calories are strategies focusing on attentive eating. We have several such tools at our disposal, several of which I have written about here previously. They include mindfulness training, slow eating, and food habituation (eating the same stuff day after day).
