6 Hypothesis & Research Question
Hypothesis is the potential explanation or mechanism to the Research Question.If we try to research what result in obesity, then there are lots of possible hypotheses. We try to explain in science and social science perspective.
Research question should never be equal to the fact, and it’s must be a theoretical one.
6.1 From Science
1, In evolutionary biology, in case of hunger or unstable envrionment, evolutionary selection make us to prefer high-calorie food, and feel more attractive.
2, Genomics， Ceratin genes can make our body much easier to store calorie.
3, Microbiology， Intestinal Flora affect our digestion procedures
4, Biochemistry, How stomach send the signals to our brain.
5, Neuroscience, How our brain handle incentive of food.refined/calorie
6, Medicine, Some disease can cuase obesity, like metabolism.
others, like diet, sleeping, pressure
6.3 Rethinking Hypothesis
Should we take as much explanation as possible ?
Should we call one approach is the most convincing ?
How do we implement a multi-discipline research ?
6.4 Hypothesis & Literature Review
How research question, literature review, theoretical framework and hypothesis connected?
Theoretical framework in literature is the most important resource to figure out the hypothesis.The meaning and contribution should start from existed research.

6.5 Hypothesis & Proving
In social science, from the hypothesis to proving is much difficult. Circular argument is a serious problem. Another thing need to be clear is there is no way you can prove one research question, just one or two mechanism.
