This is just a general question to you or other posters: does having a leaner body fat allow to consume more calories and maintain that leanness? I know that’s not a straightforward question (or answer) but what I mean is does the amount of calories that can be consumed increase as we get leaner or is it still a function of muscle mass held, physical activity, NEPA etc.? If I’m not clear please let me know and I’ll try better to explain. Thank you.[/quote]
Hey, sorry so long in responding (house full of holiday guests until this afternoon).
In my experience, being leaner has not allowed me to take in more calories–in fact, the leaner (and therefore lighter) I have gotten, the fewer cals I’ve been able to consume. I suspect there are several reasons for this, among them being that 1) basal metabolic requirements seem to scale linearly with bodyweight; and 2) once you get to a certain level of leanness, the hormonal milieu seems to shift to a ‘fat protecting’ mode. (This can be envisioned as a reduction in the slope of the function relating BW to BMR.)
If anyone has had a different experience (ie, the ability to increase their caloric intake as a function of getting leaner), please chime in.[/quote]
This has been my experience too. I’m right there with you about weight and calorie intake.
I also think that generally when people are leaner its because they are doing more cardio than when they are carrying around 5-7% more body fat to get to that level of leanness… So they might be expending an extra 1,000-1,500 calories a week on cardio, so if they eat an extra 800-1000 calories of carbs they are still in a deficit. Then when they arent as focused on getting/staying lean they ease up on the cardio and have to back down on the food too.
