26 Apr 2017 --- A new study has underscored the idea that low fat, high sugar "diet" foods play an important role in unwanted weight gain. Researchers from the University of Georgia found that rats fed a diet high in sugar but low in fat increased body fat mass when compared to rats fed a balanced (rodent) diet. Moreover, the rats fed a high-sugar diet were more likely to experience a range of other health problems, such as liver damage and brain inflammation.
