Dear Sir or Madam,
I am a 25 year old woman that has always been underweight and has struggled (and still does) to gain weight. I currently weigh 55kg, which is the highest weight I have ever been. Since I do look very skinny, having nearly no chest and a very scrawny upper body (waist about 64 cm), people accuse me of having an eating disorder, which is an illness to be taken seriously, however I luckily don't suffer from. I have never been on a diet to loose weight, rather the opposite. I always try to eat as much as I can to gain weight. I started to work out once or twice a week, mostly weight training and only very little cardio, in order to gain muscle mass.
My sister weighs about 54 kg after having a baby boy and has always weighed less than me, but looked more curvier and healthier. She also does not eat well, only little portions and only twice a day (an estimated calorie intake of 1500). I do eat 3 times a day, mostly double the amount, sometimes even triple, and also snack, but to no effect... And sometimes still feel hungry after 2 hours. Why is that? And what can I do to make myself look a little more like the 25 year old woman that I am? Thank you very much for dealing with my question!
