Jogging while significantly overweight risks damaging hip, knee and ankle joints. Stick to walking, for as long as it takes to register some permanent weight reduction and take up fast walking before running.*
Obviously consult your GP before you set out on an exercise regime, due to blood pressure and heart health issues.
*Walking is less energy-efficient than running and burns more calories per mile. If you opt to run -and- set goals in terms of distance, rather than time, the tendency will be to cover 'n' miles and then stop. As you gain fitness, you run faster, finish sooner and might burn fewer calories than walking for a set duration (eg 30 mins/day).
