Really bad advice
on June 12, 2013
My doctor told me to loose weight. He recommended the GI Diet book.
My wife is a nutritionist and so I got a copy of the book and looked it over with her.
It's fair enough to assert that most people consume too many calories. They do. Myself included.
It's also fair to promote eating more vegetables and smaller portions. We should.
It's also fair to say that not all calories are equal and some impact us more harmfully than others. Agreed.
However, the information in this book in regards to fats is very old-fashioned and not in step with current research.
For one thing, promoting totally artificially produced, preservative laden margarine over natural, unsalted butter is crazy.
The evidence that 'saturated fats cause heart disease' has roundly been disproved. It is much more complicated than that and has as much to do with consuming crappy carbs and nutritionally-starved foods in conjunction with them.
As well, the advice to eat low-fat products sweetened with Aspartame and Splenda is also equally outdated and old-fashioned. For god's sake. Update this book. You can get natural Yogurts without any sweeteners or sugar in them. Add honey or maple syrup to taste if you need a hit of sweet. It's much lower on the Glycemic Load than cane derived sugars, and it's extremely unlikely to give you cancer.
Fat Phobic and Calorie-restricitng diets are dangerous and old fashioned.
I should hope that the authors do their research and update this book. There's plenty of good advice in it, but the assertions that all saturated fats are 'very bad' is nonsense and the promotion of chemical sugar supplements over natural, low Glycemic Load sugars like maple and honey is just wrong and dangerous.
And finally, the very idea of the Glycemic Index is outdated and should be replaced with a fuller understanding of Glycemic Load.
