Default Fed vs. Fasted Cardio

Advanced Muscle Science: Fed vs Fasted Cardio

Fed vs Fasted Cardio
Although the following research did not measure lean body mass, I'm sure those of you who practice intermittent fasting will appreciate this news.

A new study out of Tunisia looked at aerobic trained males and compared fat loss as well as total bodyweight between the two groups. What they found was interesting and for me unexpected. The fasted group lost slightly less total bodyweight. But at the same time lost significantly more fat (6.2%). This suggests they also had a greater retention of lean body mass. Unfortunately I'm unable to currently access this full text so many questions are left unanswered. However it still appears to be excellent news for anyone on the fasted cardio band wagon.

Effects of fed- versus fasted-state aerobic training during ramadan on body composition and some metabolic parameters in physically active men.

Abstract The aim of this study was to evaluate the effects of aerobic training in a fasted versus a fed state during Ramadan on body composition and metabolic parameters in physically active men. Nineteen men were allocated to 2 groups: 10 practicing aerobic training in a fasted state (FAST) and 9 training in an acutely fed state (FED) during Ramadan. All subjects visited the laboratory for a total of 4 sessions on the following occasions: 3 days before Ramadan (Bef-R), the 15th day of Ramadan; the 29th day of Ramadan (End-R), and 21 days after Ramadan. During each session, subjects underwent anthropometric measurement, completed a dietary questionnaire, and provided fasting blood and urine samples. Body weight decreased in FAST and FED by 1.9% (p < .001) and 2.6% (p = .046), respectively. Body fat percentage decreased only in FAST by 6.2% (p = .016). FAST experienced an increase in the following parameters from Bef-R to End-R: urine specific gravity (0.64%, p = .012), urea (8.7%, p < .001), creatinine (7.5%, p < .001), uric acid (12.7%, p < .001), sodium (1.9%, p = .003), chloride (2.6%, p < .001), and high-density lipoprotein cholesterol (27.3%, p < .001). Of these parameters, only creatinine increased (5.8%, p = .004) in FED. Creatinine clearance values of FAST decreased by 8.9% (p < .001) and by 7.6% in FED (p = .01) from Bef-R to End-R. The authors conclude that aerobic training in a fasted state lowers body weight and body fat percentage. In contrast, fed aerobic training decreases only body weight. In addition, Ramadan fasting induced change in some metabolic parameters in FAST, but these changes were absent in FED.
