This begins by asking a question. In that case, the question would be: Does Sensa cause weight loss without dieting? Background research would then need to be done. This would include any literature and other research information that could be found on Sensa from reputable sources. Information from InStyle and Good Housekeeping would not be considered for this type of research, because these are not reputable magazines from a scientific standpoint. A hypothesis would be constructed from the background research, which would be that Sensa causes weight loss without dieting. From that point, it would be necessary to conduct an experiment to prove or disprove that hypothesis. An experiment to prove or disprove this hypothesis would need to include a control group, and that group would need to eat the same food and the same quantity of food as those using the Sensa. This is difficult, because everyone metabolizes food differently and may have different...

Still, very similar people could be used in order to see if the control group lost weight in the same way as the Sensa group, or whether the Sensa group actually lost more weight through the use of the product. All other things (height, weight, medical conditions, etc.) would need to be equal. At the conclusion of the experiment, the data collected during that experiment will have to be analyzed, which will allow the researcher to draw conclusions about what occurred while the experiment was taking place. From that point, the results of the study can be communicated to others, so they can draw their own conclusions about the way the experiment was conducted and what it means for them.
