When I went keto I lost over sixty pounds without even trying, while taking the same dose of that drug. I don’t believe that it’s the anti-depressant. The first thing to look at is the carbohydrate content of your diet. Take a good, hard look at the nutrition labels on your food, and most especially, take a look at the lists of ingredients. U.S. law permits manufacturers to manipulate the serving size shown on the label, so as to be able to claim 0 g of sugar. But if you look at the list of ingredients, you may be surprised to find sugar (under one of its many aliases) right up there at the top of the list.
Secondly, your carb tolerance depends on how insulin-resistant you are. It is possible that 20 g/day is still too much, for your particular situation. Richard and Carl settled on that recommendation because it works for almost everyone, but people who are significantly insulin-resistant may have to limit their carb intake even further.
Third, the artificial sweetener may be raising your insulin level and thus inhibiting your weight loss. (A further problem is that certain brands of stevia actually blend it with sugar, which is another reason to double-check the labelling.) Switching to a different brand, or to stevia drops instead of a blend, or to a different sweetener altogether may help. Or cutting out sweetening altogether might be an approach that works for you.
