What do you think burns more body fat?

The article below doesn't really address the question but it does point out that you can measure fat oxidation and that it does vary at different exercise intensities. It doesn't address post exercise oxygen consumption and caloric burning. Which may be big factors in the overall daily calorie balance sheet. More importantly, I think, is that different workouts effect appetite differently. This is almost certainly why running (and maybe even walking) is more effective for weight loss for me: If I swim early in the AM I am hungry all day (currently thinking of eating my keyboard) and want to eat lunch at 9 no matter what my breakfast was. If I run early in the AM, which I hate, I don't even think about lunch until 1. J Strength Cond Res. 2009 Oct;23(7):2090-5. Quantifying differences in the "fat burning" zone and the aerobic zone: implications for training. Carey DG. Health and Human Performance Laboratory, University of St Thomas, St Paul, Minnesota, USA. Abstract The primary objective of this study was to examine the relationship of the "fat burning" and aerobic zones. Subjects consisted of 36 relatively fit runners (20 male, 16 female) who completed a maximal exercise test to exhaustion on a motor-driven treadmill. The lower and upper limit of the "fat burning" zone was visually assessed by examining each individual graph. Maximal fat oxidation (MFO) was determined to be that point during the test at which fat metabolism in fat calories per minute peaked. The lower limit of the aerobic zone was assessed as 50% of heart rate reserve, whereas the upper limit was set at anaerobic threshold. Although the lower and upper limits of the "fat burning" zone (67.6-87.1% maximal heart rate) were significantly lower (p "fat burning" zone and MFO, indicating a need for measurement in the laboratory. If laboratory testing is not possible, the practitioner or subject can be reasonably confident MFO lies between 60.2% and 80.0% of the maximal heart rate.
