I do not eat fruit when I am on a diet to lose weight. Just clean diet (meats, eggs, nuts, lots of vegetables, few types of oils and butters, mostly no dairy, no fruits (maybe a little of berries), no junks...) and exercise. Fructose is metabolised different than glucose and is bad to eat when trying to lose weight, you would not die of course or something like that, it would just slow the process. But otherwise when losing weight is not a primary goal I eat fruits, but max 1 fruit per day or equivalent of berries or other smaller fruits.
