Looks like you have a great attitude about weightloss. Exercise and healthy eating will always get the best and fastest results.
The only thing I would change is to replace some of the carbs with lean proteins for your morning and evening snacks. All that sugar spikes your insulin and turns on the fat storing hormones so you must slow down that insulin response with some type of protein/fat if you want to lose the weight fast. Good protien choices are: cottage cheese, hard boiled egg, small piece of chicken or fish, chickpeas or hummus, whey protein powder (no sugary protein bars).
One of my favorite snacks is 4 oz of organic vanilla yogurt mixed with 1 tablespoon of organic whey chocolate protein powder and 5 almonds or walnuts. Has the consistency of a pudding, is very satisfying, and will keep your insulin under control so your body stays in fat burning mode all day.
Also I would try to work all the larger muscles not just the legs. Work back, chest, and legs three times a week and then cardio and abs 3 days a week working on a different area of your abs each time you train (day 1 lower abs, day 3 obliques, day 5 upper abs). That is the best ab training tip I've ever learned from my scientific core conditioning course.
