High-fat diet-induced obesity in animal models

N Hariri, L Thibault - Nutrition research reviews, 2010 - cambridge.org

Obesity and leptin resistance: distinguishing cause from effect

MG Myers, RL Leibel, RJ Seeley… - Trends in Endocrinology & …, 2010 - cell.com
Because leptin reduces food intake and body weight, the coexistence of elevated leptin

[HTML][HTML] The blood-brain barrier and glutamate

RA Hawkins - The American journal of clinical nutrition, 2009 - Elsevier
Glutamate concentrations in plasma are 50–100 μmol/L; in whole brain, they are 10,000–
