According to the National Weight Control Registry, successful weight loss maintainers "perform about 1 hour of moderate-intensity exercise each day
A high level of physical activity was common to 90% of participants, although very intense exercise wasn’t necessary since 76% of participants reported doing brisk walking. Weight training, cycling and aerobics were the next most common activities, and many people used more than one activity, so it’s about the amount of exercise not the type."
Do you exercise for an hour a day? That seems like a lot to me, but it may be what is required to get there and stay there for a majority of us.
