Struggling

Lately I have been struggling hard core with my eating and motivation to go to the gym.   I love riding my bike and going for walks on the greenbelt, but I know they aren't doing the job as far as max calorie burn goes.  The worst thing is that I am not resisting temptation well at all.  Every where I go at DirecTv there is food.  Cookies, candy, doughnuts, ice cream, pizza...all free.  It isn't just at work that I am eating the wrong food.  I crave Junior Bacon Cheeseburgers, frozen yogurt, and french fries.  It is not a good thing.  I don't work out more than 2 days a week and I have 0 motivation to actually go to the gym.  I have only worked out with my new trainer once and am supposed to go back on Tuesday.  I was doing great for 6 weeks and then everything got thrown off.  I need to get back to the place where I was going to the gym 6 days a week and eating right.  My project has been much more difficult than I ever thought it would be.  My doctor has said that weight loss and lifestyle changes are something that are 3 years in the making.  It takes 1 -2 years to lose the weight and 1 year to maintain the weight loss/make it a permanent lifestyle.  I think my problem is impatience.  I am not seeing the progress that I want so I am becoming apathetic.  I know that eating junk food isn't going to get me to my goal, so I am going to have to just bite the bullet and get back to the business of losing weight.
