Your hatred of soda is class snobbery and fatphobia. Do you know what else has tons of sugar in it? FUCKING FRUIT. christ almighty. Just stop talking about nutrition 99.9% of you b/c you don't know anything and you're perpetrating stigma.
Keto is extremely unhealthy and only marginally increases fat loss as compared to regular calorie restriction. Don't go on keto unless you're interested in developing liver disease, kidney disease, heart disease, etc.
