All diets work.
They all boil down to one thing. Consuming less calories than you burn. You cut out sugar? You’re eating less calories. Intermittent fasting? You’re eating less calories. Atkins? You’re eating less calories.
They key isn’t about which works better than the other, it’s which works for you. What diet are you going to stick to?
You love bread? Atkins isn’t going to work for you so maybe you try intermittent fasting.
There are nuances, sure, but ultimately, they all do the same thing.
