The issue, as outlined by others. is the lack of calories. While it seems counter-intuitive to increase calories, it is the only way you will be able to lose weight. And again, others have said this but you clearly do not understand, at least yet, how to manage/ create a diet which will help you reach your goals in the best way possible and are instead opting for shortcuts rather than trying to solve the issue. If you do decide to run winny, I hope you have a well designed PCT to run into afterwards.
Also, and I don't mean to call you out, but how long have you actually tried dieting for? You seem a little off with your numbers. In one thread it is 1.5years and in this one it is 3 years; from this I make the assumption that you haven't really tried at all, or haven't actually really been monitoring your food intake (throws into doubt the 1300kcal 'guesstimate'). I may be wrong but i'm putting it out there.
A well developed diet will dictate weight gain or lost whilst an exercise program will cater to physiological responses to exercise rather than be a sole determinant of weight loss.
