You don’t need as low as 20, try something less ambitious, say 40. Also, are you even hungry at breakfast? It’s the easiest meal to dodge
Are you sure 40? Why is it all the keto forums and blogs seem to insist on 20g as the cap/goal for ketosis to occur? Will 40g still begin the ketone process?
And I don’t really eat breakfast. I eat err “brunch.” But then I need a small meal as a snack before my workout, which is usually leftovers from half of my brunch. Then after my workout I have dinner.
