Hi there,
I am in my 3rd week and have amazing energy BUT in week 2 I had a couple days I felt very weak and like I might faint. I upped my water intake a lot because I read in the book that you lose a lot of water with the fat leaving so you must drink a lot (I forget how much).
Also take t easy on yourself through week two as the energy does seem to come back for all. I feel more energetic than I have in years but week 2 I thought, ” how are people exercising? ”
A doctor I know told me it takes a little while for our bodies to figure out where to find fuel when we switch from carbs to protein. It keeps looking for carbs for days and then once it figures it out we feel great again. It’s that few days it doesn’t know where to look that we feel weak. As if we hadn’t eaten almost.
Best of luck everyone!!!
