Candidates for lap band surgery are generally individuals with a body mass index over 40 kg/m2, or are more than 45 kilograms over their ideal body weight. Side effects, risks, and complications from lap band surgery should be discussed with a surgeon or physician prior to the operation. Set small goals and focus on these rather than the "big picture." Decide where you want to be in a week or in a month rather than focusing on the total amount of weight you'd like to lose. Avoid surroundings where you know you're tempted to make poor food choices.
