The article references a few studies that conclude that there is "no significant difference" between a low carb and a low fat diet. It also suggests that whether a keto (or any other) diet will work is an individual thing:
> In this regard, saying that “diet X is the best way to lose weight” is probably not a globally-correct statement given the evidence so far. Instead, it should be the much less interesting: “no diet performs meaningfully better on average, but there exists some diet that is the best way to lose weight for you.”
This matches up with my experience. I know a lot of people like yourself who swear by a low-carb/keto diet, whereas I find I have no problem maintaining a healthy weight (BMI=22) with a fairly high-carb diet with a lot of rice, noodles, pasta, oats and bread. I actually feel very unsatiated when I'm just eating meat/vegetables alone.
I love to eat, and once or twice a week I'll literally eat until my stomach physically hurts (and I do mean literally, kind of like how some people feel after a Thanksgiving dinner). I exercise, but not a lot - probably 3-4 hours a week. I'm not saying this to brag, or to make overweight people feel bad (I'm sorry if I do), but just to give some anaecdata to balance out what the keto people are saying.
One thing that I should mention is that I don't really eat much sugar, apart from fruit, and sports drinks and energy bars when I'm doing long bike rides. I just don't enjoy the taste of soft drinks (I almost exclusively drink water, and sometimes coffee or tea), or most heavily processed foods (most of my meals are home cooked, or at non-fast-food restaurants). I also find the sauces that most restaurants slather on food to be overpowering and over-sugared, so I don't eat a lot of that either (although this seems to be a US-only problem).
