I saw a nutritionist when I first started. She was somewhat helpful but not everything that I wanted. My expectations probably were not very realistic.
The biggest thing she did to help me was to give me a big list of food, several pages, that I
could eat. That was huge to me because I truly was at a loss about what to eat. I knew that most, if not all, of my normal food would be on the no-no list.
My biggest problem with her is that she want to tell me exactly how to eat. Fancy that, an expert wanted me to follow her advice and I was stubborn about it.
She wanted me on an exchange program that would be about 1200 calories per day. I was already calorie counting and wanted to stick with that but she said I would be too "obsessive" with cc. I wanted to cc and felt that I could not handle 1200 long term. I had tried many times and wanted a gentler start, calorie counting with a range of 1500 to 1800 calories/day. She said that my weight loss would be too slow and I would get discouraged.
I thanked and paid her; than took her program and tweaked it to work for me. I used a combination of exchange and calorie counting to ensure that I got in all the food groups. Her list of foods were a huge help.
My weight loss has been relatively slow, 63 pounds in 10 months. I may have lost more on 1200 calories/day but I doubt that I would stuck with it.
