sc69 saidIf your "Shape" meets the requirements of your lifestyle, and you're healthy - then you're probably "in shape"...
+1 I like this
I read long ago that BMI and body fat testers can be inaccurate for skinny people because the un-fit ones have "hidden fat" within their muscles! At least we hide it well.
Actually no to the first quote. If your lifestyle requirements involve waking up, waking to car, driving to work, taking elevator to your floor, desk sitting, elevator back to ground floor, car to home, and sitting while watching TV for hours until bed time, then just because your body meets these requirements does not mean you are in shape. You would have a poor metabolic profile, if not now, eventually.
Yes, skinny people can have marbled fat muscles. It is the same thing as with raising veal cattle. They avoid letting the cattle do physical exercise because it makes their meat less supple and marbled, reducing flavor, at the cost of the health of those who eat the meat and slaughtered baby cattle itself.
Muscular people can have marbled fat muscles too. It is called the 'not lean' look.
Actually, in terms of overall mortality and health, overweight but physically active are protected from health morbidity, whereas underweight but sedentary is considered dangerous.
For men, you should weigh plus or minus 10% of the answer to the following equation:
106 lbs for 5 ft and +6lbs for every inch over five feet. So, a 5'10" male should weigh 166 plus or minus 16.6lbs according to the equations we learn in dietetics.
>110% over but <120% over is considered 'overweight,' and >120% over is considered obese. <90% of standard weight is considered underweight and dangerous, and diet and exercise education would be tailored to this person to gain muscle and weight in general.
Of course, the equations do not do as well with muscular people (I don't think there is much research on how much muscle is too much muscle in terms of being metabolically healthy--correct me if wrong). They also don't do as well with non white people (obviously they were created when most research was done on white people), they don't do as well with pregnant people, and they don't do as well with dwarfism, amputation, and paraplegia/quadriplegia.
