I've been following The Hacker's Diet (had 7kg to lose to get to my 'ideal' weight) and it's been relatively easy. At some point I plan to blog all the data, but I've been consistently losing about 0.6kg per week since I started 5 weeks ago.

Quick summary of what has worked for me:

1. Stopped eating anything between meals. I probably cut out 12 cans of Coke, 2 chocolate bars, and 2 cakes/treats per week. I estimate this at 2,640 kcal alone

2. Started listening to my stomach so that I'd stop eating when I was full, and didn't take second helpings that I didn't actually need.

3. Have been following the exercise plan and now avoid taking lifts or escalators.

4. I am not counting calories for my meals since excluding my between meals rubbish I eat fairly balanced food.

Also I'm saving money... basically I'm losing weight, feeling better and saving about 26 Euro per week. Since I plan to cut out that stuff permanently I'll be able to afford a spanking new iPhone after 6 months.
