On your lifetime no-diet plan you follow a nutritionally wise eating plan to enable yourself to progressively lose weight until you level off at your desired weight. You won't have to change your diet at that point because you will have already changed and stabilized it.
The following are common but tested techniques that you can work into your no-diet plan to support a lifestyle change in your eating habits:
1. Get rid of fattening foods such as cakes, cookies, potato chips, and other non-essential snack or dessert items, and then don't restock them.
2. Drop one fattening component from your diet each month. Pick the most fattening first (ice cream or cake, for example).
