When I was on the job in the health industry, the quantity of men and women that would ask me about fat blocking and fat burning solutions was incredible (think high caffeine and then guarana). They usually speed up your metabolism which will come with longer term negative effects. The reason behind this's that they raise your heart rate that will end up raising cortisol levels. If you know something about cortisol then you will understand that this prompts the body to hang on to body fat (hint: I think this is why stressed people battle to loose weight).

WHY COCONUT OIL FOR Fat loss?
Without trying to be technical, coconut oil is a saturated fatty acid which is predominately a MCT oil (medium chain triglycerides). This's very different to the majority of the vegetable oils sold today.
The short as well as medium-chain essential fatty acids which may be located in coconut oil (and grass-fed butter that I use too), are routed directly to our liver and used straight for electricity. So this means:
1. It doesn't get saved in fat cells as simply as long chain fatty acids, as well as create ketones which gives us a constant source of energy
2. Enhances thermogenesis which increases fat burning
3. Helps eliminate food cravings with enhanced thoughts of satiety
According to Christine Cronau's book the Fat Revolution, one can find studies of participants that have been fed the same diet plan which wasn't created for weight loss. But several of them had been given medium chain fatty acids and they lost weight, whilst the weight in the majority of the group remained the same.
What's more, it compared diet programs with three types of fat consumption. Low fat, coconut oil and belly juice ingredients - discover this - monounsaturated fat. There seemed to be a 60 % reduction in body fat storage for the groups consuming coconut oil.
