Yeah, it it makes a massive difference the GI index of the sugars in the food one eats, so for example it’s a lot better to consume pulses (like chickpeas) than it is pasta, since the latter is pretty much just starch and (after cooked) water whilst the former is a far more complex food with also lots of protein and fiber (only talking about macronutrients here).

Mind you, this diet of mine is not because of overweight, it’s to keep Type II Diabetes under control with as little insulin as possible and to get it into remission (so far, it has worked very well having reduced the need of insuline by about 80%), so it’s based on studies that have been done on this and is much more tightly controlled with regular checking of blood sugar levels.

But yeah, a lot of it is to reduce the intake of low GI sugars (I used to be a big consumer of bread, for example, since I live in a country with really good bread, and that stuff is for special occasions only nowadays), which means quite a lot of cuting down on carbohydrates consumption but also means replacing some with better sugars (so, say, pulse or peas instead of potatoes or pasta)

Mind you, part of the problem is that my work is sitting down in front of a computer, so even with regular exercise I simply need a lot less sugars than I used to eat - if was naturally more physically active in most days beyond the whole walk to work and back thing and two 10km runs a week, cutting down so much on carbohydrate-rich foods would’ve been a bad thing.

Still, its pretty amazing by comparison just how much excess of sugars there was in my diet previously and that was even with some care with what I ate and quite a lot of sweets avoidance.
