Avoid foods like refined suger, white rice and white bread because they are considered empty calories. Don't listen to idiots who advocate extremely low carb diets, those only work short term and they rely more on the dieter feeling full from eating protein rich food not some kind of special metabolic secret - if you actually have some will power you won't benefit at all.
Idiots? Really?
My understanding is that when you consume sugar (carbs are sugar) insulin is called upon to shuttle the sugar into the fat cells, and the kidneys retain sodium and therefore water. In the absence of insulin, which happens on a low-carb diet, glucagon is produced, which calls upon the fat cells to release their fat stores, which is then burned for energy. Additionally, sodium is released by the kidneys as is water.
A low carb diet seems like an efficient way to lose some fat, but if someone follows it and then returns to the same diet that got them fat in the first place, well, common sense says they'll gain their fat stores back.
