It's hilarious that people describe their anecdotal experience of being in a calorie deficit as a proof that "intermittent fasting works". This was never the question, but whether intermittent fasting brings additional weight loss benefits as compared to calorie deficit with frequent meals.

My anecdotal experience from 20y of bodybuilding and doing ~3 cuts a year: for cutting, I tried IF, 6 meals a day, low fat, low carb, high fat true keto, balanced... everything works. And works equally well - this is backed by numerous studies. The only difference is the impact on health parameters (different will get worse on low fat vs high fat), satiety, and how easy it is for someone to sustain the diet and stay in a deficit. This will depend on the lifestyle and personal preferences. So my preferred way to cut is high protein, low carb, essential fats, a ton of fiber. When building muscle I go high everything but balanced.

Anything else and more is sectarianism and people bragging about their choices not having verified their true claimed efficacy or benefits.
