You’d be shocked if you took a hard look at food ingredients. They put sugar in EVERYTHING these days. Even when they don’t outright list sugar, there are actually 56 different words for sugar, fructose, sucrose, etc. It’s appalling what food producers have done to our health because of their lust for money.
I follow Dr. Berg on YouTube and his short chalkboard lectures are amazing. While I have seem to hit a plateau in my weight loss, I did lose 40 lbs fairly easily, and that was from dropping simple carbs, ie; breads, sugar, rice, pasta, etc.
Give him a look. Do a search on his channel for any specific questions you have. He’s got thousands of videos it seems. I’ve learned a lot from him and I feel better than I have in 20+ years.
Best of Luck to you.
