Aquarius: January 21 - February 19
Due to the logical strength held within the average Aquarius, they tend to have no problems sticking to the goals in diets or otherwise.
However an Aquarius is prone to a wandering and sometimes eccentric mind that could see them rebelling - the key is make the diet appeal to their already existing sensibilities.
As somewhat of an individual you won't want to follow a diet which everyone is doing. Instead make your own regime and food diary to stay motivated instead of just becoming another member of the herd. Just keep on going like Geena Davis, star of 'Thelma and Louise' famously endorsed!
