A literature analysis supported links between  sugar  intake and both total energy intake and body weight gain , and between sugar intake and blood triglycerides independently of total energy intake .
The effects of sugar on blood triglycerides were shown to be mediated by the fructose component of sucrose and were observed with an intake of fructose > 50 g/day .
In addition , prospect i ve cohort studies showed associations between sugar intake and the risk of diabetes/insulin resistance , cardiovascular diseases , NAFLD , and hyperuricemia .
Reduction in consumption of sugar-sweetened beverages is associated with weight loss: the PREMIER trial.
BACKGROUND Consumption of liquid calories from beverages has increased in parallel with the obesity epidemic in the US population , but their causal relation remains unclear . OBJECTIVE The objective of this study was to examine how changes in beverage consumption affect  weight change among adults . DESIGN This was a prospect i ve study of 810 adults participating in the PREMIER trial , an 18-mo r and omized , controlled , behavioral intervention trial .  Measurements ( weight , height , and 24-h dietary recall ) were made at baseline , 6 mo , and 18 mo . RESULTS Baseline mean intake of liquid calories was 356 kcal/d ( 19 % of total energy intake ) . After potential confounders and intervention assignment were controlled for , a reduction in liquid calorie intake of 100 kcal/d was associated with a weight loss of 0.25 kg ( 95 % CI : 0.11 , 0.39 ; P < 0.001 ) at 6 mo and of 0.24 kg ( 95 % CI : 0.06 , 0.41 ; P = 0.008 ) at 18 mo . A reduction in liquid calorie intake had a stronger effect than did a reduction in solid calorie intake on weight loss . Of the individual beverages , only intake of sugar-sweetened beverages ( SSBs ) was significantly associated with weight change . A reduction in SSB intake of 1 serving/d was associated with a weight loss of 0.49 kg ( 95 % CI : 0.11 , 0.82 ; P = 0.006 ) at 6 mo and of 0.65 kg ( 95 % CI : 0.22 , 1.09 ; P = 0.003 ) at 18 mo . CONCLUSIONS These data support recommendations to limit liquid calorie intake among adults and to reduce SSB consumption as a means to accomplish weight loss or avoid excess weight gain . This trial was registered at clinical trials.gov as NCT00000616
