Hey SueMarie - you are right. Everything I have read says not to go below 1000 calories a day because it just slows down your metabolism. Most say to keep your calories between 1200 to 1400 calories a day to lose weight. If you have gone from 2200 calories a day down to 1400 to 1700 a day you will lose weight.
The problem is I have a low thyroid. If I eat more than 1200 calories a day I gain weight. sad but true. Most people with low thyroid tend to keep their calories around 1000 to 1200 a day and maybe lose 1 pound a month if anything. The only way I could eat more calories would be to exercise more, which I probably should, but can't find enough hours in the day. So my calories are low because of my low thyroid.
About the water, I use to have a hard time getting in the recommended 64 oz a day but the more I drank it the more I liked it and the more I wanted it and I have just made a real effort to drink drink drink that water. Also I'm in Louisiana and it's hot and humid and it's easier to get the water in. I don't get as much water in during the winter time, but at least my 64 oz. I have heard that we should be drinking half our weight in water. In another words, if I weigh 200, I should be drinking 100 oz day and that the 64 oz recommended is for someone who is "normal" weight. I've heard it is possible for someone to drink too much water, but it's not very likely to happen (if that makes any sense).
hugs,
cathy
