Fat Metabolism in Formerly Obese Women: Part III Energy Expended During Exercise

Continuing on from Part I and Part II:

Fat metabolism in formerly obese women
Ranneries, et.al.  AJP-Endo, 1998.

Overview:  An impaired fat oxidation has been implicated to play a role in the etiology of obesity, but it is unclear to what extent impaired fat mobilization from adipose tissue or oxidation of fat is responsible. The present study aimed to examine fat mobilization from adipose tissue and whole body fat oxidation stimulated by exercise in seven formerly obese women (FO) and eight matched controls (C).  They measured:

• Lipolysis in the periumbilical subcutaneous adipose tissue 
• Whole body energy expenditure (EE) 
• Substrate oxidation rates (glucose, fatty acids) 
• glycerol release (fat mobilization)
