I'm hoping the good folks of FSU might point me in the right direction. An older family member who has a bunch of medical issues has lost significant weight in the past few months, and can't seem to gain it back, or when she puts on a few pounds, she loses them again quickly. My worry is that she needs the weight to fight off her other issues - heart, digestive and stress related - and that her medical doctors don't know enough about nutrition to really help. She's always been thin, so losing even a bit of weight puts her on the brink of seriously underweight and unhealthy. Apparently part of the issue is that she is not absorbing nutrients - food goes right through her without doing much good. Because of her heart issues, she worries about cholesterol and artery clogging fats, so she sticks to low fat foods and margarine, which to me lack in nutrient value. She does eat a lot of veggies and fruit, not too much meat, loves pasta, likely not enough whole grains. At her doctor's recommendation, she drinks a Boost every day. Anyone know of a diet that works? Some tips? An online resource of some kind? Every time I try to search, of course there's tons on *losing* weight, and when you finally find something about gaining weight, it's usually directed at body builders and recommending big tubs of protein supplement.
