Weight loss and perseverance
I don't post up here much but I have a similar situation in regards to changing my eating habits.
I am currently going keto-a lifestyle change more than a diet. I am not sure that this is the best way to go for everyone out there but I did pick up a few thoughts that everyone can use in their day to day eating.
Number one-sugar. Eliminate it at all costs. That means sugar that everyone adds to coffee and in baking but added sugar in your processed foods and sugar you don't think of in juices (a glass of OJ that has the juice of 10 oranges also has the sugar of those 10 oranges), fruits and vegetables.
Number two-sugar. It really is terrible for you that is why I list it twice! Watch the documentary "Sugar Coated". Definitely eye opening for me.
