Hello!
I hope I am posting in the correct place, I am new here. I am posting because I am concerned about my parents who are both in their 80s. We all started this diet about a year and a half ago, and are all very happy on it, except my parents keep losing weight. They have been on an intermittent fasting diet for about 20 years, so they eat all their meals in about 5 hours, and have maintained steadily their normal young-adult weights. But since cutting dairy and meat (they ate very little meat anyway) they have been steadily losing and now weigh less than they ever have before. They eat loads: breads and nut butters, oatmeal, fruit, they seem to be doing everything right. In some ways it seems good, because they have both lost stomach fat, and I understand that what they need to do is maintain and build muscle, but it's difficult at 80. They are active and seem healthy, though not as strong as they used to be. They refuse to go to see a doctor.
They don't want to stop intermittent fasting as they love it, they don't want to go back to eating dairy and meat, and they don't want to exercise with weights because they say they don't have time.
But they are worried about the weight loss. What can I suggest to help them stop losing weight? And even more importantly, is it safe for people in their 80s to be on this diet if they are so thin? (We all really want to believe that it is because we like eating this way.)
I saw a table somewhere on this forum that suggested correct weights vs height, and they are at or slightly below those weights. (I will have to ask them again to be exact, because they haven't told me their weights for a while and I'm not sure I remember correctly)
Thank you for any insights!
