Yup I totally agree with what the last poster said - at 16.7, your BMI's still too low hon. Mine's still only 15.4, got a long way to go yet. Am currently on a weight-gain diet, pretty high too coz I workout alot (love my exercise, and that's not just a purging thing either.) If you're not menstruating either, you're in trouble. I'm already getting severe back pains in my lower spine - the area cited as most at risk when i had a bonescan in Bethlem Hospital's ED unit - and am currently trying to gain enough weight to start my periods off again in the hopes of preventing osteoporosis setting in, if it already hasn't. If it has, the back pains will be due to small fractures in my spine, caused by excessive exercise on a low bodyweight for the past 5 years. I've not had a period since Sep 2001, and wsa 16 at the time they stopped, so I could've grown another inch or so, damnit! What I'm trying to say is, for God's sake, don't stunt your growth now and don't let osteoporosis set in. Even if it don't get you now, it could in later life when you've not got enough bone mass to support your muscles/organs/daily life, and when your estrogen levels drop with menopause - bam, you're in agony and virtually unable to walk. Trust me on this one, coz I saw enough old ladies stooped over in pain in the EDU to last me a lifetime. Scared me more than seeing the little girls on the ward.
So my ultimate advice to you? Get your weight up pronto. To hell with BMI, it's totally inaccurate anyway - look at atheletes with so-called "obsesity" at BMI level 30. They're packed with muscle!! Get weight-training so you gain healthy lean muscle weight - yes, you WILL HAVE TO EAT ALOT TO SUPPORT IT but it's better than sitting on your ass all day gaining fat, isn't it?! Keep cardio levels MODERATE so you don't lose fitness - walking/gentle cycling and jogging, no more than 3x/week, to warm up/cool down after weight training. Do the latter 3x/week for 46mins/1 hour. Cardio, no more than 20 mins, max (if jogging/cycling.) This is only a ROUGH GUIDELINE ,ok? Get to see a dietitian who can help you with your individual needs. If you're not an adult yet, you're still under the care of your 'rents I'm afraid - but this doesn't mean your Mom gets to dictate everything to you. Look at it this way - this is how one of my mates on the EDU put it - would you rather be sitting around on a ward all day, eating tons of ****e and gaining fat, coz you were forced into going there to gain weight.....or would you rather be gaining weight the healthy, INDEPENDENT way by eating a high-cal but HEALTHY diet, supplemented with weight-training and light cardio? I know which I'd choose, hon. Get your act together, and gain some weight. I'm doing it, and I'm scared outta my wits - but it's for my future. I want my life back.
