I'm wondering if this is just me but both times I have embarked on MFP (this time around just to undo lockdown weight) in the first few days I feel what I can only describe as feeling hot at night for no good reason.
Now it's not hot-hot, I'm not sweating, the heat seems to be localised internally
I even checked the radiators, which were off.
It's tempting to think 'oh i'm BURNING cals!' but I can't remember reading other examples on these forums.
