Simply because of how strict keto is I began to read the breakdown for every single thing I purchase in the store. This may seem obvious to all but I never did it to the degree I do now. There is sugar in everything and the serving sizes are often completely ridiculous - I saw a protein bar where the serving size was half the bar! Other diets teach you food groups to eat and encourage but don't seem to have this side effect of teaching you just how messed up some packaged foods are.
