Biggest Loser Diet Day 2

September 18, 2008

I gotta say I love this diet so far. I was a bit weak last night and got into a couple of things I shouldn’t have, but I still kept a 430 calorie food deficit. I worked out twice though, swimming in the morning and elliptical at night for a total of 875 calories, so my total deficit was 1300 calories, 300 better than yesterday. I was a little sore this morning, but I am good. Motivated to do it again.

I weighed in at 209.6 this morning, down another 1.2 lbs. I should not have any more “water loss” days now.

My new elliptical has the brain the size of a walnut. It is clueless as far as calories burned. First of all it does not ask for age or weight, so how it can calculate calories is beyond me. Another weird thing is it tells you METS. So I can see that I am doing 10.0 METS for example (hard workout) and METS are defined as how much oxygen you use per pound of body weight as a multiple of your resting rate. So 10.0 METS is burning 10 times the number of calories you burn at rest. So if they don’t ask for weight, then the whole thing is just a guess. If there is a weight sensor that is one thing, but there is nothing in the pedals so I am doubting this. If it doesn’t have weight then it can’t estimate your resting rate so it can’t multiply the METS number times anything that makes sense as an individual. 

I am going to test it though, my wife and I are going to do a fixed METS workout and compare calories burned. If they are the same then we need to apply our personal multiplier. So it said I burned 850 calories in 45 minutes. Now I think this would be possible, and it was a hard workout, but I don’t know that I did that much. As compared to the YMCA ones where you enter your weight it seemed quite a bit high. I also calculated what it was using for the calories multiplier. I did 7.0 METS for 10 minutes and it worked out to 160 calories per hour per METS. Now this is correct for a person that weighs about 350 pounds or so. I am going to reduce the calories it reads by about 65%. Which is a real bummer if you know what I mean. Still working on figuring out the METS and heart rate and calories burned. This stuff is hard to research for accuratcy anyway. So I am still working on that.

One more thing I must add. I am loving the snack I have eaten the last two days. It consists of half a cup of plain unsweetened yogurt, and half a cup of berries. I had blueberries the last two days and raspberries today. I toss in a half a packet of the sweetleaf stevia sweetener that showed up recently and it makes for a tasty treat. It is 110 calories and since I am not really hungry, I eat because it is snack time, it is just the perfect treat. If one started to get creative with the flavors these things could be full fledged desserts, but they are quite healthy.
