Well done on the weight loss so far. Without knowing your complete history, or hormonal balance etc, I would recommend limiting carbs to 100g and under. 'Cheat meals' size and frequency will depend on you - some people can binge for a weekend, others can only handle one cheat meal a week. Try and eat well 90% of the time.
As for exercise, try throwing in some good strength work - barbells, dumbells, kettlebells, bodyweight etc. Running IMO will give you a skinny fat look.
If you are not keen on the gym, try a book called convict conditioning - it's all bodyweight strength work. It is a long term program, and is more for 'wirey' strength rather than bulking up. Or kettlebells - if you have been instructed by a trained professional - a cheap and very effective way to get a great workout at home. Running is not the best way to get the physique you want.
If you target your carb intake around your workouts, and lower them on non-workout days you should get results. See my previous posts for protein/carb/fat ratios. Fat is so, so, so important. Keep the foods you eat as natural as possible, and unrefined and you will see results.
A constant calorie deficit is not healthy, and the body will do the opposite of what you want it to - its clever like that. Survival is most important to the body.
If you have been a low carber, for a while, try to slowly introduce carbs back into the diet, rather than all at once.
