It doesn't matter if you squeeze it fresh or make it from concentrate.

In either case, you're drinking lots fructose that's been separated from fiber. Without fiber, there is nothing to slow digestion of that fructose, so you end up with a massive glycemic impact. Alongside that, fructose directly causes leptin resistance, resulting in overeating.

Also beware of eating too much fruit all at once. Fiber can only do so much, and a stomach full of oranges will also lead to the same result.
