Hi Carol,
I like the PT way of eating but it does take some getting used to. I don't have a ton of weight to lose - maybe 10-15 pounds - but diet has always been my downfall. I know what it means to "eat clean", and I do 90% of the time, but I've never been good about figuring out what proportions work for me. And if I have a day of not eating very much, I tend to think, "well, I can have a huge bowl of ice cream because my calorie intake was so low today."
PT is about as structured as you can get, down to the last calorie or gram. You have to be a little compulsive - OK, a LOT compulsive/anal - to hang with the program. It's very carb-heavy and they are heavy carbs - rice, pasta, bagels, shredded wheat, oatmeal are staples for me. Because you have so many calories to eat every day, at least in the early stages, you skimp on vegetables because they're just not calorie-dense enough. You also cut back on fruit due to the sugar content. I love vegetables and fruits and this has been my biggest adjustment.
You also have to eat many small meals or you'll be stuffing down huge heavy carbs at 10:30PM just to get your food in. That takes some getting used to also - my body was programmed for three meals and a snack or so, and now I'm eating six small meals and drinking a gallon of water a day.
If you're interested, I'd encourage you to take the free diet analysis. It's eye-opening - I was eating way more sugar and sodium than I thought, plus a lot more fat (even though it was healthy fat from nuts and olive oil).
Lemme know if you have any other questions...
Happy Turkey Day,
Allison
