well...from my experience bits and pieces from what everyone is saying goes, but something i dont necessarily believe works or is smart for us cfers to do, and that is drop fat intake, unless you dont have degestion issues and you digest everything perfectly. The reason for us having to consume more fats than "normal" people is because we dont digest it properly so the essential fat soluble vitamins A,D,E and K are in shorter supply for our bodies therefore we have to take suppliments to give us more. The next thing is tho fat has the most calories per gram, it also takes more calories from our bodies to process/digest them. My opinion of the best way to lose the weight is to make you body adapt to what it has to go through. It is a big mistake that people make when they hear you have to eat less when it's not necessarily so. The thing is you can eat the same total amount of food per day but space it out, like someone said, in 5-6 sessions of eating and eat more often well rounded meals but with (maybe) smaller portions (depending on what your current eating habbits are). The reason for this is when you eat larger meals with longer intervals between meals (2-3 meals per day) your metabolism slows down and goes into a sort of starvation mode which it basically stores up fat because to it doesnt know when the next meal will be, and your body uses less to function. But by eating smaller meals more frequently like 5-6 meals per day (so total probably the same amount of food just spaced out) it kicks your metabolism into high gear and not into starvation/store up for rainy day mode. All this also has to be coupled with exercise. To me weight trainng is the better option as it burns lots more calories to perform the exercises as long as it's done with weights that you have to force and work to move (kinda pointless using weight that's the same as your mayonaise jar that you take out of the fridge to make a sandwich everyday), plus the good thing is that it will help build muscle which really is what tones and creates that firm look you girls want, and bare in mind that maybe you dont necessarily need to lose weight, like I'm always telling my girlfriend if you are to replace gram for gram of fat with muscle to get nice and toned and sexy you'd probly weigh mor because muscle is denser and heavier than fat, always keep than in mind so instead of watching the scale watch your appearance, watching the scale is only for people that have considerably high bodyfat percentage.
And back to the point I was making on not cutting down fat, eating smaller portions that are well rounded (in our case if we are enzyme defficient higher in fat than what is required by "normal" people) coupled with exercising the fat can actually cause an extra kick in the metabolism as I said because it takes more calories from your body to process/digest it as opposed to carbs and protien (simple laws of Physics tells this) so with you speeding up your metabolism by having an exercise regime and eating smaller portions more frequently then having a good amount of good fats your metabolism is in overdrive!...And that to me is the better way to do it. Actually many people do the worst thing because they know no better and dont research and are lazy, and I've seen this so many times, most people dont know that protien (if taken in excess of what is required by your body to do it's activities) will also convert and store as fat and at amuch quicker rate than fats and carbs because again your body uses less energy to convert/digest it! so lazy people that are fat just read and hear on TV or what ever "eat low carbs because your body stores it as fat and dont eat much fat because it's bad for you! and that way you'll lose weight, look so and so did it!" Worst mistake! because sitting on their buts doing nothing, having a slow metabolism and doing that will only make things worse as they will be taking in probly the same amount of calories but using less to process and store it that translates to more going to storage to me! most dont realise this and want an easy way out without working much.
Anyway hope I've helped
