Building Your Own Diet Plan

you should have asked before you bought it.
I dont know the book, but here is my take on diets:
having a flat stomach is all about diet, and less about fitness. fitness helps but it is nutrition that is the key to weight ‘management’.
with teh right intake of food you can control the weight imbalance in your body. try cutting your meals in half.
you dont need sit ups to have six packs showing. we all have them but its the fat that stops us seeing them.
you need to reduce your calorie intake by 500-1000 a day for a while. but realistically its all about quality nutrition, not starving. starving yourself triggers the body’s survival retention mode and will only leave you holding more weight when you do eat. try cutting your meals in half and having more (but smaller meals) for a start. so instead of 3 meals and the odd snack, have 6 dedicated meals evenly spaced out. this helps stop your body from excess storage, and you may be surprised with the results. same amount of food, but controlled sizes.
no fads, no diets, just maintenance of eating habits.
and its safe! my workmate tried it, and nothing else, and after 3 months had a smaller stomach than the over hang he used to have.
a little cardio (say a 20 minute run) every 2 days will help as well, but your calorie demands will rise too.
toned muscle has a higher metabolic demand than un-toned muscle so having good fitness also burns calories (not much, but still helps) when you are doing nothing. so weight training can help more than cardio alone
set realistic goals.
