All you really need to remember is to cut down on carbohydrates. Fat, protein, gluten, anything else, not an issue. Carbs n sugar is your enemy, whether they’re ‘natural’ like fruit sugar or honey, or processed. You’re doing all the right things, you’re asking questions and addressing the problem. Just read packets and maybe try logging your meals on an app like My Fitness Pal - that’s what I use and I find it really helpful along with testing.
