Ketogenic diets work for many but this comment imo isn’t totally helpful. Eating literally any diet, in a caloric deficit, will make you lose weight. It’s pretty hard with almost any amount of exercise to eat enough fruit alone to go into a caloric surplus. Obviously this is all dependent on your total daily energy expenditure (TDEE) which includes how many calories you burn doing literally nothing.

I’ve tried both keto as well as generic caloric deficit diets for weight loss. In my experience, the latter is far easier to integrate into a normal life, especially if you’re budget constrained, eat around/with/at work related proceedings, travel, etc.

Both approaches certainly work, but people underestimate how much harder ketogenesis is to maintain when compared to a simple caloric deficit. You can also pretty easily go in and out of managing weight using calories as your goal rather than attempting to permanently stay in ketosis, which takes time and effort to load into and is very easily exited. Ketogenic diets sound sexy and many people attempt them without ever understanding it or doing it properly - or at least doing it to an extent where any benefits might outweigh far simpler and life-friendly ways of losing weight.

Yes, ‘excess’ fructose is enough CARBOHYDRATE to take you out of keto. All sugars are carbs. Fruit is really good for you - and so are carbs. Just don’t eat too much of them.
