If kid has BMI under 20 is that ok at 18>?

If kid has BMI under 20 is that ok at 18>?

Common sense: A boy needs no body fat, a girl only a little bit. Many elite track athletes have bmi's that put them "underweight". If junior is growing up fairly happy, is adequately muscled and is able to keep up with others in his favorite sport, stop worrying about his bmi. It was never intended as an ideal for individuals, and life's difficult enough. Encourage study, skill acquisiton ; fitness, not eating. ...Read more

What's the average BMI for 20 year old females?

What's the average BMI for 20 year old females?

Depends on height: Hi. BMI is a measure of body habitus that is calculated using your height and weight. It does not take age (in adults) into account. So 20 years old doesn't matter. Height, however, is indispensable in calculating BMI. Therefore, in the absence of critically important information, we have no way to tell you what an average BMI for (20 yo) women is. Good luck! ...Read more

Depends . . .: How many eggs you're allowed to eat each day depends not upon your body mass index, age, gender, etc but rather whether you have heart disease or not, high cholesterol or not, and who you ask and when - b/c opinion (and science) change. There's also a difference btwn consuming yolks (which contain 200mg cholesterol) & whites (none). Most recommend no more than 300mg cholesterol/d (or 1 whole egg) ...Read more

Hi LDL: Hi. Your BP is excellent. Your LDL is high and your HDL is not great. Your triglycerides and calculated VLDL are great (and suggestive of good insulin sensitivity). You're young, and it's hard to recommend lifelong preventive medicine sometimes for some people (not for me or for many others, however). Glucose > 100 - was that fasting? If so, that's abnormal; if not, probably OK. I'd treat LDL. ...Read more
