you dont know as much as you think you do, not to be rude. your "interval" training, doesnt leave you gagging about ready to puke, does it? if not....your not doing it correctly. it doesnt mean pedal on a stationary for a minute and then bust *** for the next minute, then slow down, the speed up, then slow down. interval = the puke drill in baseball. jogging 1 lap, sprinting 1 lap, jogging one lap, sprinting one lap. or jogging 30 seconds, sprinting 1 minute. that's interval.
and your deal with sitting on the couch eating carrots.....proves you dont know as much as you think you do. if you are both eating ~2000 calories, you...nor him....would be 35 pounds over weight. no lie. your body burns more than that in a day, easily. if it didnt, your BMR wouldn't say so. I'm guessing your ~150-170. at 160, you would be burning ~2450 a day with light activity, and sedentary job. so at 2000 cals you would lose maybe a pound a week. possibly 2, depending on work out calories burnt.
until you cut out soda, fast food, pizza, breads, and all that other white carb crap, your not eating correctly 2000 cals or not.
