I feel like this too. I had such a sweet tooth most of my life and it took a diagnosis of gestational diabetes (with my 3rd baby at the age of 44yo) to give me a swift kick up the bum.
I am not over my need for a treat yet and it’s been the best part of 9 months since I started eating low carb and keto.
This past week I stepped it up again when I stopped drinking goat’s milk (and cow’s milk). It’s the first time in my life that I have not had milk in almost 2 weeks! It was really hard and the only way I have done it is to use coconut milk from a can to put in my cups of tea. And I make a sweet treat for myself with cocoa and carob powder, coconut oil, coconut milk and desiccated coconut - and that’s my crutch at the moment. I’m still eating cheese and make my own goat’s milk yoghurt as well, which can help if you’ve got issues digesting all the meat fats.
But it’s really hard when you’ve had an addiction to any kind of food - or any kind of behaviour around eating. You’re always surrounded by food so it’s always a temptation. Let’s hope you don’t wait for a major health crisis to snap out of it - but if you do, you would be like most people. Most of us don’t change until we hit a wall.
