Since you'll be needing a new hobby, gardening is a really good way to, not only distract yourself from the times when it is most difficult to stop overeating but also, get well-acquainted with the foods that will make you less likely to overeat.

Something to do with your time
 
It is a fact that much of the overeating leading to obesity happens when you have "down time." Perhaps more importantly for those who have office jobs or occupations that otherwise encourage sitting, this includes just about anytime you're sitting still enough to eat a typical chip or crisp.

Not only is planting and maintaining a food garden a useful hobby that saves you money, but you have good odds of being rewarded with fresh, bountiful produce that will encourage you to cook your own food, one meal at a time.
 
Plenty of leftovers
 
When planted in even a very basic sort of succession, a garden plot will provide a parade of fresh produce over most growing seasons. This can provide you with as much as three-quarters of the year where you will be challenged to make a meal out of vegetables and fruits that can help stop overeating on several fronts.
 
A tomato plant in a pot isn't going to cut it
 
you need to make a real commitment to see if you can always have something ready to eat. Especially if its the sort of food you think you'd like but haven't bothered with learning what to do with it. This can be done in a succession of plots, in a particularly sunny backyard, or even where the lawn used to be in the front. 

As an added bonus, your neighbors will have a chance to see how much better you look and feel as they see you tending the garden over the course of the year.
 
Learning how to cook all over again
 
it's important that one of the things you accept when you say, "I'm going to really do something once and for all, stopping my overeating problems," is that you become flexible. You may have to learn how to do several things you thought you know, all over again. Cooking is one of them.
Ethnic foods are often a good way to learn how to use the bounty of the season. You're relying upon vegetables to require you to actually do something with them before they're fit to eat -- even if it is just a bit of washing. Go ahead and plant turnips - then learn what to do with them - the whole plant, greens and all. The result is very often a nutritious and delicious meal that you'd not have even considered, otherwise.
 
Eating veggies to loose weight
 
Just going to the bother of cooking, for most people, helps combat the tendencies to focus on calorie-dense foods that make obesity so insidious. It is also socially acceptable to eat the type of foods and amounts that make obesity such a common pitfall. 

The odds of you overeating on radishes are a lot lower than those for snack-cake binging. Moreover, the consequences of a snap-pea overdose are very small compared to an ice cream pig-out. 
 
Waste not, want not
 
You may be surprised at how the planning that goes into keeping vegetables and fruits into the constant rotation of your diet will really have a profound impact on what you choose to fill up on. Most people can't stand to see food go to waste, and as part of your commitment to stop overeating, you'll make a pledge to not let another vegetable languish into a puddle in the crisper drawer.
