Basically the age-old method of diet and exercise, but I only ate chicken salad and worked out at the gym 3~4 times a week.

No caffiene, sugar, salt, bread, etc... which also meant checking the ingredients and skipping pre-packed (ie flavoured) meat with things in, etc.

So, the right idea, but just too intense. And of course, it didn't last.

Even now, eating chicken (and other meat alternatives) salad wraps, but with coffee, etc, I can't get anywhere near my ideal weight. But, my current job is long days of hardly moving, so it's the physical part I'm missing.
