I have read half of this book and the other half awaits me. It is actually quite good. She does make a lot of sense.
The main idea behind it is that food should really be enjoyed on all possible sensual levels. She writes engagingly and enticingly, I found. I really like her style. She stresses that losing weight should not be a torturous affair and that we torture ourselves when becoming fixated on the scales, food-weighing and calorie-counting. This makes sense to me. One big hint...it's the thought put into obtaining food, preparing food and presenting food, then ENJOYING the fruits of our effort that we should really spending our calorie-energy on, rather than focusing on caloric intake, inches gained/lost and guilt-tripping.
The book also looks at everyday ways to increase energy expenditure, like taking the stairs instead of the lift.
Where her ideas would apply to someone like me, for example, is my love of coffee. Mireille would say something along the lines of, instead of drinking copious amounts of CRAPPY coffee all day, have ONE coffee a day made from the real thing, in a gorgeous cup, and sip it slowly, playing with the froth (if you're into latte, which I am) with your teaspoon and taking in the scent. If you're want to enjoy it even more, buy the beans and grind them yourself.
