Homologous physiological effects of phenformin and chromium picolinate

McCarty, M.F.·1993·Medical Hypotheses

Abstract

The insulin-sensitizing drug phenformin, in addition to its clinical utility in type II diabetes, has been reported to lower blood lipids, reduce body fat, enhance cellular immunity, and--in rodents--to increase mean lifespan and retard the development of growth of cancer. Initial studies with the insulin-sensitizing nutrient chromium picolinate indicate that it aids glucose tolerance in type II diabetes, lowers elevated LDL cholesterol, reduces body fat while increasing lean mass, and--in rats--increases median lifespan. These effects are thus analogous to those reported for phenformin; chromium picolinate should be tested to determine whether it likewise has a favorable impact on cellular immunity and cancer risk. The ability of both phenformin and chromium picolinate to increase lifespan suggests that age-related insulin resistance may play a profound role in the aging process. It may not be coincidental that caloric restriction--the best documented technique for increasing lifespan--markedly increases insulin sensitivity. Safe, appropriate measures for promoting lifelong insulin sensitivity include a low-fat diet, exercise training, and supplemental chromium picolinate.

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.
