Obesity
Conditions
Brief summary
This study partially replicates two previous studies with normal weight women, and overweight women. Both found that women could compensate for sucrose added to the diet in carbonated soft drinks (4 x250ml total1800 kJ per day) when it was given blind over a period of 4 weeks. The hypothesis is that this applies also to obese women, who will not gain weight, increase overall energy intake in the diet, or eat differently whilst consuming sucrose. 42 participants shall be randomly assigned to either be given carbonated drinks that contain sucrose, or drinks that are artificially sweetened.
