Day 1 and 2 LOW CARB

Yesterday was my first full day of low carb eating. I have to say it wasn't too bad. I was worried about working out because my 3-2-1 class is pretty intense and I was worried I might get too light headed, but I ended up not going due to some stomach problems. But today I felt much better. I've been sticking to just 20 carbs a day. I'm suppose to do this for the first 2 weeks. The main thing I notice is that I am hungry, a lot. Maybe it's because I don't have oatmeal to fill me up and bloat me in the morning or may because the foods I'm eating are digested quicker. What I DO know is that I don't ever feel completely full. Today I went to my Zumba class, and right before I ate a low carb bread with a little peanut butter on it. When I got to class, the room was pretty warm, it was probably a little below 70 but when we were done it was at 70 degrees. I broke a great sweat though. My instructor also decided to make us do some dances that were a little more demanding, and I love that. But for today, half way through I was so tired. I caught myself looking at the clock quite a few times.... I'm hoping that this gets better and that my energy level will pick up and my endurance will be stronger for my workouts. Some of the things I have made are:
Breakfast: Cheese and Pepperoni Omelette, little bit of pepper and then a little bit of Tapatio sauce.Breakfast Burrito w/ Sauteed steak with salsa, cheese and scrambled egg wrapped in half a low carb tortilla with a little bit of tapatio.
Lunch: Broccoli and spinach sauteed in smart choice butter, chicken tenderloin and then seasoned with cajun seasoning. Broccoli with Jalepeno and cheese turkey dogs, pepperoni, smothered in Tostito cheese.
Dinner: Buffalo wings : steak burrito with cheese
Snacks: Pork Rinds with Tapatio, Sugar free caramel pudding.
Drinks: Water, Coffee with sugar free creamer
