Energy balance

High doses of added sugars (>20% of calories) in hypercaloric trials increase fasting triglycerides and visceral abdominal fat, but these effects are confounded by weight gain and total caloric excess.

If you are consuming very high amounts of sugar (over 20% of calories) and eating more calories than you burn, you may see increases in triglycerides and belly fat. However, this is largely due to the extra calories and weight gain, not the sugar itself. Reducing total calories is the primary solution.

ModerateQualifiesMEDIUM confidence
Diets containing greater than 20% of kcals from simple sugars may result in elevated fasting triglycerides... individuals also gained an average of two pounds... significance in abdominal weight gain occurred only pre-to-post in the fructose arm and this was not compared to the glucose arm.

Why this rating

Based on RCTs, but results are confounded by weight gain and short durations.
