you will get lots of varied advice here so it may be hard to know what will work.
i do know this, when blood sugar is high insulin increases. insulin pushed the excess blood sugar into cells for fuel and stores extra as body fat. as long as this process is going on you cannot use body fat as fuel.
so it is my opinion that you need to keep blood sugar low. and the marconutrient that pushes it up the highest is carbs, especially refined carbs.
the last few years i have been reading more on carb cycling and its variations. it seems to hold some good promise. the diets i feel that do carb cycling or at least minimizing carbs are the paleo diet, carb backloading, and intermittent fasting. these are not the norm diet that people use to get money and are only good for a short term fix. these diets IMO are great for a lifestyle change that lasts a lifetime.
now to keep carbs low and to get in enough food you will have to up your fat intake considerably. and by that i would be afraid to push it upwards of 40-60% of your daily intake. maybe even as much as 80-90% of the intake of 1 meal/snack. and speaking of snacks and meals i am personally not a fan at all of 6+ meals a day. all those small meals can have a similar, if not lower, effect on blood sugar levels. in that they can stay high and due to you eating multiple times it will keep being pushed up. an article was written recently by the lead editor on t-nation.com about hoe many meals a day. he claimed to have little science and he is a guy that likes his research. he goes on to show some convincing evidence using the research from intermittent fasting and carb backloading.
