Even though the drug reduces belly fat, it doesn’t make blood sugar worse — which is important because some fat-loss drugs can cause diabetes risk.

Scientific Claim

Tesamorelin (2 mg subcutaneous daily) does not cause significant changes in glucose metabolism parameters in HIV-infected adults on antiretroviral therapy with central fat accumulation over 6 months, indicating no adverse metabolic effect.

Original Statement

“Insulin-like growth factor-1 increased (P < 0.001), but no change in glucose parameters was observed.”

Assessment Explanation

The RCT design with direct measurement of glucose parameters and reported lack of change (P not significant) supports definitive language. The claim accurately reflects the absence of effect.

The study found that the drug tesamorelin reduced belly fat in HIV patients without making their blood sugar levels worse, which means it doesn’t harm how their body handles sugar.

Similar Assertions

Even though it reduces belly fat, the injection doesn’t make blood sugar worse or cause diabetes in these patients.

98%

The drug doesn’t make you lose fat from your skin or your arms and legs — it only targets the fat deep inside your belly, which is the kind that’s most dangerous.

87%

A hormone treatment called tesamorelin temporarily raises blood sugar by 7 points more than a placebo in people with HIV after two weeks of treatment, but this effect goes away after six months.

87%

A daily injection called tesamorelin helps HIV patients with a big belly lose nearly 11% of their dangerous internal belly fat in six months, while those getting a fake shot don’t lose any.

86%

If HIV patients keep taking the injection for a full year, they lose even more belly fat inside their abdomen—about 18% total.
