The Claim
Do obese people have higher insulin and blood sugar spikes after eating carbs than lean people?
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.
People with obesity tend to have higher insulin levels when fasting and their blood sugar spikes more after eating carbs, but their bodies still use the sugar from those carbs just like lean people do.
See the scientific wording
Obese adults are associated with higher fasting plasma insulin levels and a greater postprandial glucose rise after carbohydrate ingestion compared to lean adults, despite similar rates of exogenous glucose oxidation.
What the research says
1 studyStudy: Thermic response to isoenergetic protein, carbohydrate or fat meals in lean and obese subjects.
The study found that obese people had higher insulin levels before eating and bigger blood sugar spikes after eating carbs, even though their bodies burned the carbs at the same rate as lean people — which is exactly what the claim says.
