Query: English version of "Plus je mange, plus je maigris"

Michel Montignac's book, while written in a less "scientific" way than Sears' "The Zone" or Eades' "Protein Power", provides very similar nutritional guidelines.The book stresses more forcefully than the other two that the key to proper nutrition and sustained bodyfat loss is to properly combine foods (i.e., not mix protein-dense foods and starches in a same meal), so as to keep blood insulin levels under control.
