If you’re under 20g total carbs a day, you’ve completely eliminated sweeteners, and you’ve eliminated dairy, the 4th horseman of the stall-calypse is often excessive exercise.
Exercise builds muscle or VO2 max. It’s not particularly helpful for weight loss. It frequently inhibits weight loss, because it messes with satiety signals. Done properly, keto revolves around eating to satiety. If your satiety signals are getting screwed up by excessive exercise, it’s like following a broken compass. A lot of people in the “not losing weight section” mention exercising 5-7 hours per week. It’s not coincidence. Some people are able to exercise 5 days a week and still lose weight long term. Not everybody can. Try cutting back exercise to one or two 20 minute sessions a week.
If your priority is building muscle or increasing VO2 max, or if your livelihood depends on it, obviously you should continue to exercise 5 days a week. The trade-off may be a reduced rate of weight loss.
If you can’t give up exercise, and you’re committed to losing weight, the “easy button” is extended fasting. It’s not right for everybody (history of disordered eating, thyroid conditions, adrenal disorders, etc) but it always works. It doesn’t have to be anything extreme. Something as simple as alternate day fasting will burn through fat with clockwork regularity. If it’s insulin resistance that’s inhibiting fat loss, alternate day fasting will sort that out pretty damn quick. For that matter, just implementing time-restricted feeding to something like 18:6 can do a lot of good.
