Atkins was the only realy fad diet I was on, but I modified it as I began to get a better understanding of what it was actually doing.
The problem with a lot of diets is that people go on them hoping it'll work miracles, and not think into what's actually happening.
I actually bought some Xenical tablets about a year ago. What the tablets do is basically prevent your body from digesting fats... so you crap it out! "Wow miracle drug?!"... no, not exactly...
See, it sort of works, but for myself and others I know who have tried it, it basically SCARES THE CRAP OUT OF YOU (pun totally intended) so that it trains you to avoid fatty foods... You'll be at work, and suddenly need to go to the toilet because you ate food that contained some fat... when you rush to the toilet, it's not the most pretty sight... and you'll probably need to spontaneously do this several times a day.
As I've said before, Atkins really helped me lose weight at one stage because I stuck to it really strictly and exercised a lot. It wasn't the fad diet so much as it was what was going on - I was avoiding carbohydrates and my body was resorting to stored fat deposits... Simple(ish)!
Same with my freak-out diet during the HSC... the bananas were Low-GI so they lasted a few hours, and the eggplant/fried egg didn't really have much in them except nutrients (I guess) and protein, respectively.
Junk food is the devil here. So if you avoid junk food (including dessert at dinner time!) and stick to eating the food as featured on our lovely food pyramid: http://web.mit.edu/athletics/sportsmedi ... yramid.JPG
You'll be fine!
BUT, you must exercise. Walk places. I can't believe the majority of people insist on taking the bus to my uni from the train station. I mean. It's a 15-20 minute walk, but it's a nice walk and it's probably the same duration on the bus due to the traffic!
Walking is really good exercise for burning off fat, apparently, because it's low intensity... When I lost most of my weight, it was because I went for 1-2 hour walks each day. So if you can squeeze that in your day (even if divided up) then you'll be laughing in a few weeks time as you really start noticing the difference.
