I actually never recommend to people who are happy with their rate of weight loss that they should abandon their sweetners. I only suggest it as something to try when people who are using them complain of a stall or are having troubles with cravings and/or straying.
The strong response to @FishChris isn’t about his personal use, it’s about his sucralose evangelism and promotion when all the available scientific evidence points in the opposite direction.
We know that non nutritive sweetners stall a fair number of people; so whenever I see a thread where someone is making a completely erroneous claim like “sucralose doesn’t raise insulin”, or “there is no evidence that sweetners affect weight loss” I feel that these errors need to be corrected for the sake of people who may naively believe the claims.
I do exactly the same thing when I see forum members saying without qualifications that high protein is fine on a ketogenic diet. It’s not fine for lots of people which is why almost every keto doctor will recommend considering your protein amounts if you hit a stall. They do the same thing with artificial sweeteners.
The pushback in this case is to someone claiming that the evidence is vague, which it isn’t, and that it’s only a “psychological” effect when people find that sucralose is stalling them (which is what @FishChris has claimed over multiple threads).
