> Virtually every _controlled_ study shows that metabolic differences between adults are within a margin of +/- 15%, with essentially no way to eat the same amount of calories as a 200lb person and stay at 465lbs. Not least of which because your basal metabolic rate is much higher at that weight.
That sound a bit wrong to me. Fat needs energy to maintain itself? Isn't it just an energy store? If you're 465lbs with the same muscle percentage as someone 200lbs maybe that's how it works, but no one at 465lbs has less than 15/20% body fat.
- rich-cartwright 5y agoIt's more that the muscles (assuming same muscle mass) have to do comparatively more work if they are carrying around more weight.
- Zababa 5y agoThat is true but I don't think that accounts for all the metabolism. There's probably something to say about having to maintain your temperature, but I don't know if it consumes more or less energy in general as fat isolates. Wikipedia (https://en.wikipedia.org/wiki/Basal_metabolic_rate https://en.wikipedia.org/wiki/Basal_metabolic_rate) says that 70% of the metabolism comes from the organs, 20% the muscles and 10% thermogenesis. All probably grow as you gain weight, but I seriously doubt that an obese person weighing 400lbs consumes twice as much energy as someone weighing 200lbs. What I'm trying to say is that the idea that you have to eat enormous quantities of food to maintain a high weight seems wrong to me, and that simply saying that the person must be missing some calories that they consume or lying about their level of activity seems condescending to me. To change the subject, do you plan on expending Fella to Europe at some point? I really like your approach.
- rich-cartwright 5y agoReally nicely put. Yep we're British founders so would love to expand to Europe in the future. Sadly won't be for a couple of years though - lots of work to be done first in the US!
- Zababa 5y agoThanks, and good luck with the US!
- phonypc 5y ago>Fat needs energy to maintain itself? Yes. Stored fat isn't just inert fat, but fatty tissue. Made of cells that need energy to stay alive.
