damdaman, I think it'd be useful to seitan_man and others if you gave some examples of:
What type of exercise burns fat
How much sleep to get in order to get your body to burn fat
How to avoid stress (perhaps?)
What types of foods help to burn fat
What types of foods should be avoided since they will make you retain fat
No problem. While I don't necessarily follow his ideas completely, I'm a big fan of Brendan Brazier, and I think he does an excellent job of explaining about why/how you should eat "net gain" foods instead counting calories, how to avoid dietary stress and deal with the stress you do have in your life better, how to train your body to burn more fat while training, etc, than I can, so I suggest reading his book.
That being said, the goal is to eat more alkaline-forming, easily digested foods. This often means more raw foods, but not necessarily entirely. The energy your body puts into digesting food, and the stress that this can create, and also the acidic environment that is usually left behind, are major factors in how much nourishment you actually get from the food, and how much that food is actually helping your body, rather than harming it. Refined foods are the biggest culprit, flours and fried foods, stimulants (caffeine), alcohol, foods containing unnatural ingredients (flavors, colors, fortified with things), etc. Metabolic acidosis can occur from creating an environment in your body that is too acidic from these kinds of foods and from sources of stress. Metabolic acidosis, among other health issues, causes a reduction in growth hormone and an increase in cortisol (stress hormone), leading to retention of body fat and loss of muscle. Additionally, eating too little and not providing your body with the nutrients it needs is also stressful to your body, and can lead to the same hormonal response, thus causing you to lose muscle/bone density (your body will pull calcium from your bones to buffer your blood from the acidic environment) while dieting, instead of fat.
As for exercise, your body will burn mostly glucose for the first 90 minutes of exercise. To burn more fat, you want to aim for longer stretches of lower-intensity exercise. Working out for 30 minutes, even if it's a really high-intensity workout, does not burn much fat.
As for sleep, that certainly varies from person to person. But the goal should be to wake up naturally and feel replenished when you do, rather than tired and needing coffee.
I hope this is helpful. Again, I'm not nearly as good at explaining some of these things as others, but they're sound concepts that have been studied, and I recommend reading Brazier's book yourself if you want to hear more detail from a more authoritive source.
