It's not a major part (anymore ) of what I do professionally, but I still do it from time to time, so here's my quick answer:
Use more calories than you take in. Other than physically removing tissue, there is no other way.
That being said here's are some specifics:
First don't make losing weight a goal-- "lose weight is not a goal it is a process. It a means to an end, such as "achieve and maintain a weight of ______ pound" (fill in the blank with an appropriate amount.)
Next answer the question why?-- think of your answer from four perspectives:
Advantages or benefits of losing weight (the process) and attaining a weight of _____ Advantages and benefits of keeping things as they are The disadvantages and costs of losing weight and attaining the goal weight The disadvantages and costs of not losing weight Next make a plan that includes changes in eating habits (not a diet, but a permanent change) and for increasing your activity (not necessarily exercise, but you can do that if you like).
The basics of a healthy diet are pretty well known:
Decrease refined carbohydrates-- white sugar, white flour Increase fresh fruits and vegetables Increase amount of water you drink-- especially before and between meals If youeat meat, keep it lean--remember that a serving of meal is 4 ounces, aout the size of a cassette tape. I'll have more to say about this, but this'll do for now.
