I want to take this final section to add some additional points and clarity. For starters, the above advice is not for everyone. It's not intended for those who really have their nutrition dialed in, such as competitive bodybuilders and other athletes who benefit from fairly dramatic changes in their nutrition, such as 'off season' and 'pre- contest' and so on.
The chapter is also not intended for those with medical issues who may be on a specific diet to treat or manage a specific medical condition. The chapter is intended for the average person who wants to get off the Yo- Yo diet merry-go-round once and for all. As that's probably 99% of the population, it will cover millions of people.
People should also not be scared off by my "you have to eat this way forever" advice. This does not mean you will be dieting for the rest of your life and have nothing but starvation to look forward to. What it does mean, however, is you will have to learn to eat properly even after you reach your target weight and that way of eating should not be a huge departure from how you ate to lose the weight in the first place.
Once you get to your target weight - and or your target body fat levels - you will go onto a maintenance phase which generally has more calories and choices of food, even the occasional treat, like a slice of pizza or whatever.
Maintenance diets are a logical extension of the diet you used to lose the weight, but they are not based on the diet you followed that put the weight on in the first place!
Regardless of which program you choose, use the above 'big picture' approach which will keep you on track for long term weight loss. See you in the gym!
