The FastDay Forum

I started the 5:2 lifestyle last Saturday and have made it through 2 fast days (Monday and Wednesday).

I'm noticing some real benefits of fasting, including: greater mental clarity (e.g. remembering dreams better), less stress, feeling physically lighter, less snacking between meals on 'feast' days and better digestion.

However, I find it difficult to get through the fast days without getting headaches, feeling faint and just lacking energy. Is this usual for the first few fast days? Does anyone know of any ways to combat this?

Thanks.

This will pass, make sure you sip water at intervals, especially with tea, coffee and alcohol. I started getting headaches on my fast days when I started in new year, however, I get headaches whenever I diet, I think it's just a side effect.

Hi Noah, I'm just on my second day fast and have the same problem. From what i've read on here it sounds like these should pass as your body adjusts but in the meantime try to stay well hydrated and get enough sleep
