Leptin levels in human and rodent: measurement
of plasma leptin and ob NAN in obese and weight - reduced subjects.
Values for the 24 - h integrated area under the curve (AUC)
of plasma leptin, insulin, and glucose concentrations versus time were calculated above zero concentration by using the trapezoidal rule.

In another study investigating mother - child pairs, late in utero BPA exposure related to increased
plasma leptin levels in boys, whereas early exposure was linked to higher
plasma adiponectin in girls at the age
of 9 years (182).
Furthermore, and partially because
of their excellent insulin sensitivity and body composition, Kitavans had significantly lower fasting
plasma leptin levels than healthy Swedes.
Plasma insulin,
leptin, and ghrelin concentrations were measured frequently over 24 - h periods to elucidate the mechanism
of any observed changes in appetite or body composition.
Havel et al (32) reported that substitution
of carbohydrate for dietary fat increased the diurnal circulating
leptin pulse amplitude (peak minus nadir
plasma leptin concentration).

plasma leptin and ghrelin concentrations, The American Journal
of Clinical Nutrition, Volume 82, Issue 1, 1 July 2005, Pages 41 — 48, https://doi.org/10.1093/ajcn/82.1.41
Blood was sampled frequently at the end
of each diet phase to measure the area under the
plasma concentration versus time curve (AUC) for insulin,
leptin, and ghrelin.
Plasma leptin data obtained during the final 24 - h periods
of the weight - maintaining 15 % - protein diet (visit CRC1), the isocaloric weight - maintaining 30 % - protein diet (visit CRC2), and the ad libitum 30 % - protein diet (visit CRC3) 1
Our data directly address this hypothesis because we observed a decrease in
leptin pulse amplitude between visit CRC1 and visit CRC2 (decreased peak minus nadir
plasma leptin concentration and decreased AUC
of the change in
leptin) without a significant change in integrated circulating
leptin concentration (
leptin AUC).
et al 1997 Effects
of weight change on
plasma leptin concentrations and energy expenditure.
The diagnosis
of diabetes, by conventional standards, (though I believe that diabetes ought to be diagnosed by insulin and
leptin values rather than blood glucose), is defined as a fasting
plasma / serum measurement
of 126.
Effects
of short - term carbohydrate or fat overfeeding on energy expenditure and
plasma leptin concentrations in healthy female subjects.
