Earlier quoted context omitted.
The two sides of this argument always talk past each other. As someone who lost 100lbs I'm sure you know this but lots of people don't. * Calories in vs. calories out is 100% what determines how much weight you gain or lose. * Your macronutrient ratios determine how that weight is partitioned (muscle vs fat) and have some control over hormones that contribute to hunger, like leptin. The end result is that cutting out…
Unless your protein intake is severely lower than 50g/day the partitioning is minimal at best. Also you will never be fully satiated on any meaningful caloric deficit, 40-60g/fiber per day usually increases satiation. What exactly do you mean by 'standard low fat diet'?
My personal experience is quite the opposite. When I did the whole low carb thing, I was having to intentionally supplement my calorie intake because I was eating 800-1000 calories per day otherwise which I felt was too low (my BMR at the time was ballpark 3000 calories, so figure burning around 3600/day even sedentary).
The only other time in my life that I've had to make a conscious effort to eat enough was when I was on prescription adderall in high school and would sometimes forget to eat for an entire day. Outside of that, I eat, and eat too much, honestly.
I quit the keto thing after about 6 months because, frankly, I missed pasta too much, but the whole appetite suppression thing with it is very real in my experience and is one of the most commonly reported side effects I've seen online.
