Sub-diving a fixed amount of a sugar-sweetened beverage in smaller vs larger bottles could help curb their consumption but so far, no studies have tested this possibility.
In our study, published in the journal BMC Public Health, we assessed the feasibility of running a trial on the impact of bottle size on in-home consumption of cola, in which households would receive a set amount of cola each week for four weeks, in bottles of one of four sizes (1500 ml, 1000 ml, 500 ml, or 250 ml).
