The Claim
Under hypercaloric conditions for 2 weeks, both high-fructose and high-glucose diets providing 25% of energy as sugar resulted in similar increases in liver triacylglycerol content and body weight in healthy overweight men.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy overweight men consuming excess calories for two weeks, diets high in fructose or glucose caused the same amount of fat buildup in the liver and similar weight gain.
See the scientific wording
Under hypercaloric conditions for 2 weeks, both high-fructose and high-glucose diets (25% energy) caused similar increases in liver triacylglycerol (1.70% ± 2.6% vs. 2.05% ± 2.9%) and body weight (1.0 ± 1.4 kg vs. 0.6 ± 1.0 kg) in healthy overweight men, indicating that excess energy intake, not sugar type, drives liver fat accumulation.
When too many calories are consumed, the liver converts extra sugar into fat because it cannot burn all the energy fast enough. This fat builds up in liver cells regardless of whether the sugar comes from fructose or glucose.
What the research says
1 studyWhen overweight men ate extra calories from either fructose or glucose, both groups gained about the same amount of weight and liver fat. This means it’s not which sugar you eat, but just eating too many calories total, that causes more fat in the liver.
