5. Study Description
Brief Summary
To determine whether low calorie diet (LCD)-induced weight reduction caused changes in plasma metabolites and metabolic traits from baseline.
Detailed Description
Over a 12-week clinical intervention period, a randomized, controlled study was carried out; overweight subjects consumed a LCD (approximately 300kcal/d deficit, n=47) or a weight-maintenance diet (control, n=50) were included for analyzing plasma samples and metabolites using an ultra-performance liquid chromatography and mass spectrometry (UPLC-LTQ/Orbitrap MS).

Intervention Description
Recommend to consume usual diet during 12-week study period
Intervention Type
Behavioral
Intervention Name(s)
LCD group
Intervention Description
Recommended to reduce calorie intake (a 300 kcal/day); educated to take out 1/3 of a bowl of rice from per meal a day for an easier application of 100kcal deficits, thereby reducing a 300kcal/3 meal/day
