It's actually easier than it sounds. First, start working out regularly; the goal is to get to the point where not working out makes you uncomfortable the way, for example, not brushing teeth does. Once you reach that point, you're all set on the excercise front, because the will power required will be little, just like you don't need much will power to make yourself brush your teeth (I assume). Now you can approach changing your diet. Start by making sure you don't have any "bad" food in your pantry. If you WFH, that's fairly easy. If not, take brown bag lunches with you (and don't work in fancy startups that offer free meals and snacks :p). Some people allow themselves one day per week when they can eat whatever they want to make it easier on themselves. After a while of this you start noticing that you don't crave sugar, carbs, starch, etc. at all. You still enjoy it, you just don't get so much kick out of it. For example, you start noticing that the desserts you used to eat before have become too sweet for your taste.
