Feeling faint/dizzy

[Gwdihooooo]

I’ve been fasting unofficially for a year or so now. Basically not eating breakfast and waiting until around half 12-1 to eat. I normally finish eating around 8 and eat well… with the usual treat every now and again.

But recently there’s been a few times when I’ve felt faint at around 11ish. So I’ve ended up breaking my fast early.

I tried to fast for the full day on Weds. I finished early to take my ds to have his cast off in hosp at 14:00. I felt so pathetic as I had to lie down I was so so faint. I nearly fainted and felt really sick.

I have low blood pressure. Do you think fasting just isn’t right for some? It’s a shame as I’m feeling the benefits in other ways and don’t actually feel hungry. Just suddenly light headed

It is because you are depriving your body of the necessary nutrients, so your body is reacting by being unwell.
My car won’t get to John O Groats on the 1/4 tank of petrol I currently have in it. ( live in English Midlands )
eat enough food every day for your bodyto be healthy

Honestly this not good for you xx

How are people managing to fast for longer periods? Do you do any exercise? I’m a pretty active person.

If you are active you need to fuel it, with food.
fasting really doesn’t make any proper scientific sense, it is a fad

cars who drive further every day need more fuel: people who are active need more fuel.

please eat enough food, every day

I also have low blood pressure and I struggle with fasting. I get that shaky low blood sugar feeling and need to eat something. I personally did better eating breakfast and a late lunch in my window, but I know that's not ideal for most people.

If you are doing a lor if exercise and don't have a lot of fat a short fasting window (12-14 hours) will still be beneficial, listen to your body.

Also if you are exercising protein synthesis is far more effective before 10am so you may want to rethink your window e.g 9am to 7pm with a high protein breakfast and stop eating at least 2 hours before bed.

Interesting you say that on the fasting board. I’ve been reading the benefits and don’t really see it as a fad. But accept that it’s not for me

There is no scientific evidence that longer fasts are beneficial. That doesn't mean people don't do them and find them beneficial. But there is no evidence.

The way fasting works is the first few hours you burn the sugar from the last meal, then you burn stored glycogen from the liver and muscles, then you burn fat. So if you have done this a long while you may have less fat stores, and you may have had less gylcogen on those days. The process of getting from burning sugar to fat takes about 10-12 hours, so if you fasted 8pm to 10am you'd still get benefit. If you don't eat until midday it can effect your circadian rhythm i.e. sleep pattern and quality, its advisable ideally to have some kind of protein usually by about 10am as this sends a signal to the body, I forget which one but this was on a Zoe podcast.
