When my mom started induction she stuck to it like glue, but it took her almost two weeks before she started losing. But once she did, it went really fast! To add insult to injury, my stepdad, who had started with her, was losing fast right off the bat.

I agree with the others though, your friend is eating a lot of foods that are not on the induction list. Its difficult to get into heavy ketosis when you are eating foods that are not for induction.
