Whoever said you can't make cauliflower tasty hasn't seen this recipe.

When German supermarket giant Aldi posted its Cauliflower & Cheese recipe on Instagram a few days ago it attracted hundreds of comments and more than 850 likes - with fellow Keto lovers giving it their tick of approval.

But it garnered even more attention when US food blogger Chef Resha posted the same image on her social media - revealing how the Keto diet - and dishes like this Cauliflower and Cheese she created, helped her drop 10kg and "hella inches".

"There is absolutely zero pasta in this recipe, just yummy caramelised cauliflower swimming in a gooey, creamy sauce loaded with cheese," she said about the recipe, according to New Idea.

In case you don't know, followers of the Keto diet must cut out all refined sugars, carbs including pasta, bread, rice and chips - which is why this "mac n cheese" recipe was a huge hit.

"I knew that if I were going to be successful on this diet, I'd have to make delicious keto versions of my favorite comfort foods," Resha said.

"It's working, because I'm down over 20 pounds (10kg) and hella inches, and continuing to melt. My energy is through the roof, clarity is my best friend, and I just get so much more done."

Understandably, people are losing it over the drool-worthy diet dish - that seems too tasty to be true.

"Made this for dinner tonight and whew child!!!!!!!! Soooooo good. That sauce was OMG!!!!!" one person wrote.

"Made it this afternoon. Fire!!!!!" another said.

"Mannnnnnn I made this this evening and it's beyond delicious." someone else wrote.

Aldi claims their Cauliflower and Cheese spin on "mac and cheese" is super easy to make.

"Instead of macaroni, boil cauliflower florets until tender, drain and mix in Greek yogurt, cheddar cheese and mozzarella until combined. That's it!"

Resha, 38, started the Keto diet earlier this year claiming it has changed her life - particularly rectifying her health problems.

"Since I was 7, I suffered from headaches, migraines, and chronic sinus issues. I'm THIRTY-EIGHT years old, and this is the first time in my LIFE I've gone more than a week WITHOUT a headache and ZERO sinus pressure," she said in an Instagram post.

"Feeling like s**t all the time often led to me being in the WORST mood of all time, irritated and annoyed because of my inability to feel good physically."

She said she didn't know sugar was the culprit and would never have known had she not stopped eating it.

"The knee pain went away. The sinus pressure went away. the headaches are gone. My joy has increased."

However, not everyone agrees with the diet which works by cutting out specific foods and food groups to put your body into a state of ketosis.

hey y’all. just stoppin thru. so boom, i started a #ketogenic diet a couple weeks ago. i originally planned to start it Feb 1st, but why wait? i have to admit that i’m totally a believer of the whole keto phenomenon. the hype is real. the pros heavily outweigh the cons (to ME). about me: since i was 7, i suffered from headaches, migraines, and chronic sinus issues. i’m THIRTY-EIGHT years old, and this is the first time in my LIFE i’ve gone more than a week WITHOUT a headache and ZERO sinus pressure. that fact alone brings me to tears. that sinus pressure was so debilitating that i would get this pain in my neck and shoulders that made existing difficult. painkillers rarely worked for me and i was so scared to take them cuz i’m still breastfeeding, so i would just wait til nighttime to give it time to pass thru my blood by morning. THAT sucked cuz i’d always wake up feeling just as bad. they didn’t work. feeling like shit all the time often led to me being in the WORST mood of all time. irritated and annoyed because of my inability to feel good physically. i see my little toddler smiling at me begging me to pick him up and swing him around and i couldn’t because i was in constant pain. on top of that, for the last two months, i was getting WEATHER KNEES! u know when your knee acts tf up cuz the weather’s about to be bad?? man. that was me! what i DID NOT KNOW was that SUGAR was the goddamn culprit. i would have NEVER known, had i stopped eating it. the knee pain went away. the sinus pressure went away. the headaches are gone. my joy has increased. my energy is thru the roof. i feel so damn good and i just can’t believe SUGAR was the reason i felt so tired, so weak, so fatigued. i really thought “damn i’m finally getting old”, nah lol. my greedy ass was eating sugar and carbs in abundance! the cherry 🍒 on top? i’m MELTING. my body is literally melting, and for the last four days i’ve lost four pounds. a total of 10 pounds in 14 days. the first three pounds were water, then it stalled...until a bih started doing intermittent fasting. i’ll blog about all this SOON, cuz i’ve got keto recipes to share 🥰 just giving y’all an update! ♥️ #keto #carnaldish

Sydney-based exercise physiologist Drew Harrisberg quit the keto diet after four months, claiming it is an unsustainable and unsafe diet.

He said while he got great overall aesthetic results, he experienced negative side effects.

"I am a diabetic and it affected my management really badly; I became insulin resistant," he told news.com.au.

"Unfortunately for people on keto, there's not enough science to back it up long term. I personally think it is a disastrous diet — yes, the short-term results are appealing because you do lose fat and you may look good and feel energetic with some symptoms improving, but it's so shortsighted."
