Hi

I just joined 2 weeks ago as well with a similar thyroid condition. I was always intimidated by the idea of dieting because I felt that it would be too difficult to stick to if I reduced my calorie intake so significantly. I really like food!

This is my first diet, but I am looking at it as a lifestyle change - something that I want to sustain. I would like to lose 15 - 20 lbs. My goal is to lose about .5 lbs a week, allowing me to eat about 1,600 - 1,700 calories a day depending on my exercise for the day. Most days I consume less (around 1,450-1,500 or so) - but since my goal is 1,600 there is no pressure. I figure it took me a while to gain the weight - I just need to be patient as I slowly lose it.

Adding activity to the mix helps as well - On those weekends that I know I am going out to dinner with friends I make sure to walk briskly around the neighborhood for 20 - 30 minutes - It gives me about 120 more calories that I can add to my meal if I choose!

I can't imagine that 850 calories is giving you the energy you need to get through the day. Lowering your calories too much can send you body into starvation mode and stop weight loss all together. I found a link below that backs this up if you would like to check it out!

Here is a quote I like from the link above -
"Remember that calories are not your enemy. They are a vital part of a healthy and energetic life. "Your body needs a certain amount of calories just to sustain proper function," says Lummus. This is why fad diets that force you to cut out too many calories leave you feeling lethargic, shaky, and ready to give up."

All that said - I am just starting out and looking for tips as well. Good luck with the weight loss & feel free to email for support!
