No, I'm not falling victim to the allure of the mythical 'negative calorie foods'...
But it almost seems like some fruits are! I like oranges. But I avoid them. I just hate all that work to get into them! You can bite right into a ready-to-go apple, bananas take but a second to peel, but oranges? Messy as heck to peel, and if you go with slicing you have to have a plate and sharp knife available.
They're just not worth the effort to fight to get into them.
Maybe all that effort really does add up - maybe they would be 'negative' by the time I got them in! :)

In yet another experiment borne of message board discussions, the question arose as to whether your body weight actually does make much difference in stationary cycling. One poster said that it does, because Spark gives significantly different burn rates for heavier people for the same workout. Others said that the resistance is entirely magnetic and your individual body weight is irrelevant.
So the experiment...
Using myself as an estimation, therefore pretty identical actual HRs during the two bouts, so the only variable is the weight plugged into the device...
10 mins stationary cycling at 18mph, with the weights of 250lbs and 120lbs plugged into the Bike and the HRM.
Spark Stationary = stationary cycling,vigorous, greater-than 15mph
Calories burned at 250lbs:
Spark Stationary: 219
Calories burned at 120lbs
Spark Stationary: 83
The bike and the HRM reported similar but only slightly lower burn rates for the lighter person, given the same HR recorded over the durations. Spark, which doesn't ask for HR, indicated an incredibly significantly higher burn for the heavier person, and a burn more matching the other devices for the lighter person.
Notice that Spark's figure of 219 for 10 minutes of exercise for the obese person is 22 cals per minute - which is pretty much physically impossible. Exercise almost never gets above 14 cpm, and most exercise is 6-12cpm depending on intensity and your weight. Given cycling is a very low intensity lower-body-only activity, it's incredibly unlikely that it would realistically be anywhere near 22 cpm even for the most grossly overweight of individuals.
Spark erroneously takes your weight into consideration when calculating burn on a magnetic resistance device. Neither the device, nor my HRM, report that the burn would be significantly different for a heavier person, but Spark reports a phenominal difference - more than 2.5 times the burn.
Therefore I would STRONGLY caution AGAINST using Spark's estimates for any magnetic resistance workout, and instead use an HRM, or the machine reported figure, or seek an average from other online sources.

Well, not so much. But anyway ...
Today's Spark Coach motivation is to ask myself, about my goals, "Why do you want to reach those goals so badly and how will they change your life?"
Um ... it won't.
Will I be happier if thinner? No. Happiness isn't about what size you are. If you're not happy now, getting thinner won't do it.
Will I stop being tormented for being fat? No. I'm not getting tormented.
Will my health improve? Probably - but immeasurably. I don't suffer any ill effects of weight now.
So how will it change my life if I achieve my goals? It won't. I'm still going to be the same happy, positive, caring, generous, loving and well-loved person that I am now and (hopefully) will always be.
This is why sometimes it's hard to keep those goals so in mind. It's not going to be life-changing. And I think that if you think it will, you'll be sorely disappointed when you get there.
Do I speak from experience? Yeah, I've been there. I lost 40kg a few years ago, and slowly gained about half that back. I'd like to get back to where I was. I know what it was like at 75kg weight, I know how I felt, I know what my life was like then.
It was the same as now.
But less pizza.

Sigh. The only up to date images I have of me are at run events and ... well ... let's just say they're not flattering!
It's time to be honest - that spark page photo of me is a few years and few kg's ago. There's a lot more of me to love again. I need to be honest about that and update with a real photo of the actual recent me.
But what I've got to choose from? Ugh!!!
Need to go out and take some new photos. NOT while exercising though!
