In adults with overweight or obesity, consistently meeting a weekly goal of 300 minutes of moderate to vigorous exercise is linked to a small decrease in body fat percentage over a year, with greater adherence corresponding to slightly more fat loss.
For adults with overweight or obesity, receiving daily personalized feedback through wearable devices did not lead to greater reductions in body fat or waist size than simply tracking habits on their own, and might have made long-term fat loss harder, especially for men.
In adults with overweight or obesity, following 300 minutes of moderate to vigorous exercise per week was linked to small reductions in waist size, with men showing slightly greater reductions than women for each percentage point increase in adherence.
People who consistently track what they eat, exercise regularly, and monitor their weight are more likely to maintain low body fat over time compared to those who do not.
