Slim by Design is the perfect title. Designing your environment ... small incremental changes can make a big difference.
I run a small business with 6 people. 6 people whose main interest in life seems to be either losing weight or keeping it off. No one had been very successful. Without explanation I implemented some changes. Reduced paper plates in kitchen to 8", replaced the flavored coffee mate type product containers with mini-moos (they're real 1/2 & 1/2) but don't need refrigeration, put a fruit bowl centered around the desks (Yes, I pay for the fruit) and a plethora of other small changes introduced gradually. The experiment began 10/12/15 as of today 5 of the 6 people have lost weight. The largest 25lbs, but he really worked at the other 4 averaged about 5lbs and number 6 who spends most of her time working remotely has gained and I am not asking how much.
The point is that while much of Brian's book seems directed at lunchrooms, fast food joints and restaurants it's really about how we can change our environment, get buy in from those around us and even when we can't to know that maybe sitting at the high-top is better than the dark corner.
