the issue about losing weight is controlling your feeding habits, eating more vegetables and fruits and doing regular exercise. Aerobic exercise
for 30 minutes thrice a weeks might do you some good. Walking or brisk walking for 45 minutes to 60 minutes could be of help.
Do not put it into your mind as a burden and exercise regularly with joy, take it a habit.
Think might help. You might get pedometres to time yourself to know exactly the amount of time you do walk when you do exercise. Exercise and a rich vegetable and fruit diet remain the key.
Thanks as I wish you just the best,
