The reason why I recommend low-fat diets is that to lose weight you firstly need to reduce your energy intake. Now fat provides 37 kJ or 8 kcal per gram, so for every gram of fat you cut out of your diet you are saving 37 kJ! Compared to fat, carbs and protein only provide 16 kJ or 4 kcal per gram (quite a difference I'd say). However when you do use a low-fat diet then you Also need to make sure that your total energy intake for the day is not too high because then you still won't lose weight! The Low-GI approach is an excellent way of losing weight esp if you suffer from insulin resistance. Just don't get too worried if you can't obtain all the foods that Patrick Holford recommends because he is writing for an overseas audience.
Keep up the gym work as this is making you feel good.
