You obviously don't eat fruit or vegetables too often

Looks you shocked your body quite a bit there, OP. Funnily enough, I'm making this comment while I am drinking one of my homemade smoothies. I have to ask what you put in the smoothie, though.

If you don't eat fruit or vegetables ever like only once a month or less for example. Your bodies reaction is it being shocked by the change in diet and essentially cleansing itself of unhealthy food. It would happen to someone who ate only natural non processed food if they ate Maccas as well.

you're probably not used to all the fiber. keep drinking smoothies. it won't last forever

It reminds me of the first time I ate a Fiber One bar. I know it's not a health food but it was enough to tell me that I needed more Fiber in my diet. It did give me one of the best ***** I've had in years. That's sad when you think about it.

That can happen depending on what fruit you ate and what food you have eaten the day before. But sometimes is good to clean out you system like that

Sound like you needed that extra hmph of roughage... Nothing wrong with a detox!

I'm guessing you aren't used to that amount of fruit in one hit. That's probably too much sugar for you, unless you are planning on some severe exercise to warrant that amount of sugar.

Well, you lost some weight at least

Lmao couldn't keep myself from laughing on this one. Hope you feel better op
