Fast 800 - achey limbs

3 replies

Hello
I’m 2 weeks into Fast 800 and I’ve lost about 9lbs.
one thing I’m suffering from is achey arms when doing things like washing my hair or other simple things. The ache lingers.

has anyone else suffered the same? Trying to not let my mind worry that it could be something else

thanks x

That is very fast weight loss. You are probably breaking down muscle.

I felt faint and weak too. I found it more do-able and effective when I upped to calories to about a thousand.

I didn’t lose much weight, maybe because I ate more, but it did feel like a “reset”. I was tipping into the pre-diabetic range and this did sort my blood glucose levels. Thinking of doing it annually.

I'm on week 3. It does work but I really feel like I need some carbs. I also lost 9 lbs the first two weeks. Most of it will be water weight. No aches, just low energy at times.
