Have had the same problem! Also wanting to eat completely different food - as carb heavy as possible.
In my case, I think the weather is the cause. Thats not likely to get better anytime soon so I've been trying to get my head around the change in how I feel.
Things I've done are:-
- Joined the Christmas Club to give me a goal as I am usually flexible
- Drinking more hot drinks instead of water
-Just accepting that I feel like more carbs at this time of the year, just like I feel like less in summer, and planning totally different meals. I'm making sure they are as unprocessed as possible though. Other people are saying to stay away from carbs but I was finding it really difficult and binging on sugar. By allowing the complex carbs, I find it easier.
- Only planning to do a 16:8 and continuing for a fast day if I feel like it. This felt better than attempting a fast and changing to 16:8 halfway through the day.
- The reserve, not used yet, failsafe of low calorie hot chocolate is on standby!
Today is my first fast day that has felt as easy as they had become in the summer and I think its down to being flexible and kind to yourself. We are all different, I'm sure you can tweak things a bit to get your mojo back!
Good luck
