I've been working on loosing a few inches around the waist for the past couple of months, and I finally got bored with jogging so I got a bike. I haven't ridden in almost 15 years, and it's freakin' awesome!
I had good success with cutting back my circumference while jogging and counting calories, but after riding for about 60 to 90 minutes a day for the last week or two, it really seems like my body is using up muscle instead of fat. I mean, it seems that my waist has stayed the same, but that my shoulders, chest, and arms have gotten smaller. (I also do some weight lifting about 3 hours a week, and this routine has stayed constant.) Anybody else ever have this happen?
On a related note, since starting biking I have been HUNGRY (much more so than when I was just running), and that's making it harder to keep my daily calorie consumption at a deficit. As it is, I usually have a deficit of about 500 calories, but some days it's closer to 1000. Am I eating too little, and forcing my body to cannabalize itself?
