Background: Obesity is the excessive accumulation of adipose tissue to the extent that health may be impaired. Determination of the mechanisms governing adipose deposition and body weight regulation are now a scientific priority. High dietary fat intake is generally considered to be a factor in obesity’s multi-factorial aetiology and the metabolic syndrome. Yet not all dietary fats appear to be obese genic to the same degree.Objective: To study the ...

Leptin is an adipocyte-derived cytokine critical to the integration of energy homeostasis and reproduction which putatively acts as a metabolic gate for the onset of puberty. However, it is unknown whether the age of puberty reflects leptin levels or leptin sensitivity. If pubertal age reflects leptin sensitivity, it may also reflect susceptibility to diet-induced obesity.We hypothesised that age of pubertal onset reflects leptin sensitivity. We assessed...
