Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are different amounts and different times that people will be asked to drink water, this is so that the investigators can find out if there is an optimal volume of water to drink, and a best time to drink water to reduce headaches or hunger. The least amount of water the computer could ask participants to drink is half a glass (that is 4oz or 120ml). The largest volume of water the computer could ask participants to drink would be eight glasses of water a day (a total of 64oz or 2L) spread across the day (that is not all at once). Once the computer has assigned participants to a particular volume and times to drink water, these will remain the same for every day throughout the study.
Participants will be asked to provide some brief information about themselves at the beginning of the study (for example, age, sex, height and whether you exercise, smoke or not). During the study they will be asked to weigh themselves and record this, Their dietary habits and the amount they drink will be kept on a private and confidential page on the study website. They will be asked to fill in \[2\] confidential short surveys about how they feel and their views, one at the start and one at the end of the study.
