I don't have a study, but I seem to recall that fruit juice and smoothies may be problematic.

Fruit juice is generally not healthy because it excludes most or all of the edible fruit pulp, which includes all of the fruit's fiber and much of the fruit's antioxidant content. Whole fruits, on the other hand, have been shown time and time again to be a healthy food choice for most people. > Our findings suggest that there is significant heterogeneity in the associations between individual fruits and risk of type 2 diabetes. Greater consumption of specific whole fruits, particularly blueberries, grapes, and apples, was significantly associated with a lower risk of type 2 diabetes, whereas greater fruit juice consumption was associated with a higher risk. The differences in the associations between individual fruits were not accounted for by variation in the glycemic index/glycemic load values of individual fruits. Overall, these results support recommendations on increasing consumption of a variety of whole fruits, especially blueberries, grapes, and apples, as a measure for diabetes prevention. https://www.bmj.com/content/347/bmj.f5001 https://www.bmj.com/content/347/bmj.f5001 People who look at only the macronutrient ratios (fat, carbohydrates, and protein) while disregarding everything else tend to underestimate the health benefits of fruits. Nutrition is more than just macronutrients.

My understanding is the fiber of the whole fruit is important: it slows absorption of the sugar and adds bulk to aid digestion in general. Typically some or all of it is removed in juices and smoothies. I think of removing fiber as similar to adding sugar. fwiw, I eat a low-carb diet (up to ~90g of net carbs, so not strict keto). I often eat some fresh or from-frozen fruit: blackberries, raspberries, blueberries, strawberries, orange (half a navel or a whole mandarin), or a few apple slices. I never drink juice. I don't feel fruit gives me any nutrition I can't get elsewhere. I can get vitamin C for example from various vegetables including red peppers, cabbage, and dark leafy greens. I also take a multivitamin because it's hard to get enough of some nutrients (notably vitamin D) that fruit doesn't help with anyway.
