I wanted to vent/ask for input from anyone that has an opinion.

I'm on my 3rd day of Atkins induction (yay me! )

I went on a 30 minute walk outside today and I was fine at first, but maybe 10 minutes after I started, I became completely and utterly exhausted. Like bone tired. I can normally walk for closer to 45 minutes before feeling that level of exhaustion.

I purchased some keto strips, and they are turning a light purple colour. I'm drinking lots of water, and taking all my vitamins.

I've been reading this afternoon about "keto flu", and I'm wondering if it could be that?

Is there some generic thing I need to be doing to increase my energy levels, or should I just sit back and wait/hope for my energy to return to normal in time?

Any help is really appreciated
