A have never been able to loose weight by cycling. Seems like my appetite always overshoots my calories spent. This includes heavy racing and training years ago. Now, older and fatter I have returned to cycling, and still cannot lose weight at 150 miles per week or there-a-bouts. I ride with a HR monitor, generally in ranges of 65 - 85% of my max HR (measured by self test). Then I watch the Biggest Loser TV show, and I notice that the trainers are pushing those folks at what appears to be near or over their LTs. So the question I have is, is it better for weight loss to work at very high HRs, or at lower ones. I have heard of some things where the "experts" have recommended less than optimal levels because of their belief that compliance would be higher at lesser efforts. Kind of like the recent report that walking is not enough, you really need to get the HR up. Or, is it just that at higher HRs you burn more calories in less time, so you burn more off in the same duration of effort.
What do you all think?
