Most forms of sustained lower intensity exercise will suffice here: stationary cycling, fast walking and the stepper machine being the best forms. Running is too tough on the joints and typically will burn a greater degree more muscle than will the lower impact forms of cardio, as mentioned here. So, if you can get out of bed before 7.00am and complete 45 minutes of moderate intensity cardio three times per week you will almost certainly be on the path to permanent weight loss. Probably the best reason for adopting such an approach is the fact it is relatively easy to maintain; once waking earlier becomes routine, morning cardio will not only burn fat, guaranteed - no need for any money back promises here - but will awaken your mind and set you up perfectly for the day ahead.
Talk about a catch-22: Doing something healthy, like eating a low-cal meal, can make you less likely to exercise and more likely to gorge yourself with food later on. This is because of a phenomenon scientists call licensing, which happens when we feel that we've earned the right to be self-indulgent. Most people have a tendency to want to balance things out, says Kathleen Vohs, PhD, an associate professor of marketing at the Carlson School of Management at the University of Minnesota. So when we do one thing that's good for our health, which often requires exerting plenty of discipline and self-control, we like to follow it up with something that lets us indulge ourselves.
