I can only tell you what worked for me and why it worked for me.
Everybody's psychology is different and that is what you are battling with your clients. Once psychology is account for it is just a matter of using more energy than you take in and sticking with that
I chose to try to lose about 1 pound a week because:
- I've read for years that people who choose to lose no more than 1 - 2 pounds a week keep the weight off longer, lose less muscle, and look tighter when they get to their goal. Fewer problems with loose skin if you go slow.
- Losing faster would have meant less food and would have been more uncomfortable. By being comfortable I could forget about the diet for most of my day. That made the time pass fast.
Following the Hackers Diet helped me pbecause everyday I could see the results of my habits(

I also found this article to a huge benefit to me psychologically because I now knew what to make of daily scale readings. This article kept me from getting psyched out like I did with earlier attempts at calorie counting:
