Can you guys stand one more question on the pre op diet? I have been working out at the gym 5-7 days a week since October. I just started running about a month ago. I am not killing it - I run for 1 minute and walk for 2. I have worked up to 3.75 miles in 1 hour. This is day 3 of the pre op diet and I had to really push to get 3 miles out. Does the fatigue and weakness last the entire 2 weeks or does it get ease up? My diet consists of 5 shakes and 3 bars (plus unlimited sf jello, broth, and sf popsicles.) a day. I am also much more sore and achy than I normal.

You have cut way back on your carbs, you no longer have that quick access to the energy of them. As your body switches to burning fat stores you might feel better. When I do very low carb, frankly, I feel like cr*p.

I felt worst the first 3 days of the pre-op, then it got a bit better, but I did not work out while doing it.

I too feel it's your lack of carbs. I had my surgery 12/28/11and was given a pre-op diet for 2.5 weeks and lost 12 lbs. And I even enjoyed a traditional Xmas meal with my family. I had 2-3 protein shakes, unlimited sf jello and popsicles, one fruit (excluding bananas) and one meal daily. The meal I was allowed to fill a small plate 1/4 lean protein, 1/2 veggies and1 fruit. I felt really energetic. Your body's 1st energy source of choice is carbohydrates. Since, you're consuming none it's using the protien and fat. The fatigue is not unusual with your diet change and excercise combination.
