I started my pre-op diet of 2 slim fast shakes and a salad with Protein a day on Tuesday, 3 full days ago. I have lost 2 pounds in those 3 days. I'm not having a huge hunger problem (yes I'm hungry some, but it's not a big overwhelming thing). However, I'm sooo tired. And my brain seems just slightly foggy (I tend toward a foggy brain anyway lol!).

Will this fatigue go away, or is it just going to get worse?

Here are my approximate counts:

Day 1:

~1,200 calories, 65 grams of carb, 70 grams of protein

Day 2:

~1,200 calories, 40 grams of carb, 55 grams of protein

(exercised, 30 min)

Day 3:

~1,200 calories, 45 grams of carb, 75 grams of protein

(exercised, 20 min)

So my calories are low, my carbs are low and my protein is pretty much high enough (for my ideal body weight, I should need about 60 grams). And I have been somewhat active.

It's only been 3 days! How bad is it going to be later on? Or am I going to get used to this? I just want to go lay on the couch and take a nice long nap (but can't of course!).

Oh yeah, and constipated

It gets better. I started mine on Sunday and I feel fine today. I had massive headaches and hunger in the beginning.

Your body is probably going into ketosis (depending on your carbs); that can make you feel funky for a bit.

Are you taking a multi-vitamin? That might help. I agree with the carb headache!

No, no Vitamin yet. I bought some Centrum chewables though for post-op, so I'll try that. Thanks!

On the plus side, no headache or hunger really I just feel like crashing somewhere for a few hours lol.
