Anyone Feel Sick Simply Dieting?

I'm in the process of losing weight before my bypass, but I feel sick as a dog.

I have no fever, just feel extraordinarily weak with a headache.

Could this be low sugar or protein? I've been on enough diets that you'd think I would know, but I've never felt like this.

I'm not diabetic that I know of.

Has anyone else felt like this? ?

  • That's how I'm feeling now. I'm doing my preop liquid diet and I almost feel as if I'm a diabetic and my sugar is low. I'm not a diabetic and presume it's part of my body freaking out over the change

    I need to find out if I am diabetic. I've eaten less than this when I've dieted before, and never felt like this. But congrats on your weight loss!!!!!

Also have you started removing caffeine? That can make you feel like that.

No. I'm just at the beginning stage of losing the required weight.

I do! I started my pre op liquid diet last Tuesday. I've been nauseous and light headed the whole way. And everything I smell makes me feel sick too. All I'm drinking are 5 Atkins shakes a day per my surgeon. I'm type 2 diabetic. I've lost 16 lbs though. That's a plus but, it's pure misery.

I have been on my pre-op diet for 3days now. I feel very low energy, a drained type feeling all day long. Thinking my body feels like its in shock, wondering what in the heck am I doing..LOL But I just have to simply remind myself why I am doing this. I know this hard work will reward me greatly and I couldn't be more grateful to have this chance to live life much healthier/happy. [emoji847]


I was exactly the same way the first 3 days then I started feeling better. I am type 2 diabetic as well. My blood sugars have been great on the liquid diet. I don't even feel hungry now as I think my body is getting used to this new way of eating.
