Long‐term effects of calorie or protein restriction on serum IGF‐1 and IGFBP‐3 concentration in humans
Open accessAbstract
Summary: Reduced function mutations in the insulin/IGF‐I signaling pathway increase maximal lifespan and health span in many species. Calorie restriction (CR) decreases serum IGF‐1 concentration by ~40%, protects against cancer and slows aging in rodents. However, the long‐term effects of CR with adequate nutrition on circulating IGF‐1 levels in humans are unknown. Here we report data from two long‐term CR studies (1 and 6 years) showing that severe CR without malnutrition did not change IGF‐1 and IGF‐1 : IGFBP‐3 ratio levels in humans. In contrast, total and free IGF‐1 concentrations were significantly lower in moderately protein‐restricted individuals. Reducing protein intake from an average of 1.67 g kg−1 of body weight per day to 0.95 g kg−1 of body weight per day for 3 weeks in six volunteers practicing CR resulted in a reduction in serum IGF‐1 from 194 ng mL−1 to 152 ng mL−1. These findings demonstrate that, unlike in rodents, long‐term severe CR does not reduce serum IGF‐1 concentration and IGF‐1 : IGFBP‐3 ratio in humans. In addition, our data provide evidence that protein intake is a key determinant of circulating IGF‐1 levels in humans, and suggest that reduced protein intake may become an important component of anticancer and anti‐aging dietary interventions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
