Machine Gun Kelly has fans worried after opening up about his diet which lacks what many would consider as proper sustenance.

The 35-year-old pop punk rapper  – who hit a rare red carpet with his teenage daughter weeks ago – broke down his nutrition plan as he revealed that he only eats ‘a couple of times a week.’

In a clip shared by Instagram account HipHop-N-More he admitted: ‘I don’t really eat. I just do water a bunch.’

MGK (born Colson Baker) – who ate a burger during the hangout with streamers – nodded when he was asked if he mainly fasts.

He explained: ‘Like, I ate that burger ’cause we’re streaming, and it’s my man’s s***, you know?’

One of the streamers asked that if they weren’t live online then what would MGK have for dinner.

The Home hitmaker simply replied: ‘Probably water.’

The group of streamers were left mystified by the answer as they queried: ‘But how? You don’t ever feel weak or lightheaded?’

Then MGK revealed his diet plan which many have since criticized as he said: ‘Yeah, sometimes. I’ll eat, like, a couple times a week.’

He then admitted that the meals that he actually does eat consist of ‘bone broth with kimchi and sauerkraut.’

Megan Fox’s baby daddy explained: ”Cause it has probiotics, you know? So, like, when you do those water fasts, the only thing that’s crazy is it kills all the good bacteria in you, too, so you gotta put the pro[biotics.’

Kimchi is a traditional Korean side dish (ie. banchan) consisting of salted and fermented vegetables, most often napa cabbage or Korean radish.

Sauerkraut is finely cut raw cabbage that has been fermented by various lactic acid bacteria.

Both items are fermented which is a metabolic process in which microorganisms like bacteria and yeast convert carbohydrates into other products like acids, gases, or alcohols.

As the rapper said, kimchi and sauerkraut each contain probiotics, which are live microorganisms like bacteria or yeast that provide health benefits; however, they are low in calories and macronutrients, which are essential to organ function.

Meanwhile, bone broth is a nutrient-rich liquid made by simmering animal bones and connective tissues, often including vegetables, herbs, and spices, for an extended period, typically 12-48 hours.

MGK was asked if he drinks green juice which is made from a blend of green vegetables or fruit which is a go-to for many celebs.

He replied: ‘I’ll drink celery juice sometimes, yeah. Coconut water.’

The father of two also noted that coffee and cigarettes are staples in his diet.

Fans expressed their concern in the comments section of the clip as some accused him of having an eating disorder.

One wrote: ‘Explains an eating disorder and smokes cigs as the other guys are saying he’s healthy.’

‘Bro is describing anorexia,’ another said while a different commenter posted: ‘He has the diet of a 17 year old girl who has anxiety issues.’

MGK welcomed his second child – a daughter named Saga Blade – with ex Megan Fox in March.

He is also dad to a 15-year-old daughter named Casie from a previous relationship.

The rapper celebrated one year of sobriety in August of last year.
