There is so much lies and bullshit around various diets.
If you can't lose weight because of insulin the twinkie diet would work.
People lose weight on high carb low fat diets and everything in between.

Duration: 10 weeks
Food consumed: Every 3 hours, Haub ate one Twinkie. He also consumed Doritos, a variety of sugary cereals, Oreos, and other snacks from Hostess and Little Debbie such as Nutty Bars, Cupcakes, etc.
“He also took a multivitamin pill and drank a protein shake daily. And he ate vegetables, typically a can of green beans or three to four celery stalks,” explains the article.
Haubs goal, to prove that calories count, was achieved: he lost 27 pounds in two months by eating only 1,800 calories per day, which is about 800 calories less than a man of his pre-dieting size would need in order to maintain his previous weight.
His body weight in pounds went from 207 down to 174.
His body mass index went from 28.8 (overweight) down to 24.9 (normal).
His LDL (bad) cholesterol dropped by 20 percent
His HDL (good) cholesterol increased by 20 percent
His triglycerides (a form of body fat) dropped by 39 percent
His body fat dropped from 33.4 to 24.9 percent
It's calories in, calories out and weight loss overpowers anything else.
Both low carb and intermittent fasting work only by making adherence to calorie restriction easier. Oh BTW Jason Fung lies.
However a low carb diet means avoiding foods with known health benefits. I mean if it's the only way you can lose weight, then do it, but it isn't the healthiest diet.
