Taken together, these results suggest that increased protein intake enhances the satiating effect
of circulating leptin in the central nervous system (CNS).
Acute insulin - induced elevations
of circulating leptin and feeding inhibition in lean but not obese rats.
When weight is lost, the system works in the opposite direction: Less fat means reduced levels
of circulating leptin, increased appetite, and reduced energy expenditure.

«Partial sleep deprivation may increase the risk

Food intake has significant effects on
circulating levels
of leptin and ghrelin.

of leptin and ghrelin, but also the meal composition plays a role.
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).
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).
When you eat the glucose, there are different effects than if your liver makes it, namely it
circulates for hours and leads to a spike in insulin and
leptin, that
circulates for hours, that over time will contribute to insulin and
leptin resistance... that ultimately contributes to metabolic chaos resulting in chronic diseases
of aging including obesity, diabetes, cardiovascular disease, osteoporosis, autoimmune disease, cancer, and others.

Males and females exhibited similar responses
of circulating lipids (cholesterols / triglycerides) and energy - regulating hormones (insulin,
leptin, adiponectin, ghrelin) to energy restriction, with the changes being quantitatively greater in males.
LPR - induced weight loss in women was associated not only with significant reductions in fat mass and
circulating leptin concentrations but also with the relative abundance
of bacteria
of the Lachnospiraceae family in faeces.
Low dose
leptin administration reverses effects
of sustained weight - reduction on energy expenditure and
circulating concentrations
of thyroid hormones.
I'm just confused because if
leptin resistance is defined with lots
of leptin circulating in the blood, why would those in the study with bulimics show low / normal levels?
