So one thing I've started doing is a Protein shake for Breakfast and lunch, and limiting my carbs to #1 only whole grain, and #2 only at one meal. Granted the amount of food I can eat is much less, so the amount of that carb is very little...but I limit it to one a day. For Snacks I make sure i have healthy snacks because, like you, I haven't had really any restrictions. I wish I did. I wish I couldn't eat sweets without dumping, or bread without throwing up...but alas, I can eat sweets and bread without any issue...just smaller amounts. So I've had to really re-train my thinking. I don't have things in my house that are trigger foods. I LOVE tomatoes, and have been buying the cherry tomatoes at Sams Club every weekend, then keeping them out on my counters and when I walk into the kitchen with a craving, I grab a couple of them, and then I'm good. I also really try to get all of my Water in. Before I leave work I try to make sure I have at LEAST 84 oz of water. That keeps me from snacking at work, because I'm really full with the water, haha.
My doctors don't tell me a calorie goal because my nutritionist said not to focus on calories. Focus on protein, and the calories will come. So I really don't count calories...but if I look at myfitnesspal I am usually around 1000-1200. I would say just make sure you are getting a good amount of protein in, get your water, and now that the weather is warming up maybe go outside for walks? I walk on my 2 breaks at work, and make sure I get at least a mile in, and that helps a TON. That way if I don't make it to the gym, then I have at least gotten in 30 min of walking.
Do you have MyFitnessPal? Possibly a FitBit? They've been a huge help for me!
