May I ask, are you currently under weight or around normal weiight? You seem to have experienced a really rapid weight loss which is not really normal when changing diet unless you were literally starving yourself (which doesn't seem to be the case from what you say).
I just want to say think you for mentioning this as it did get me thinking more of quantities eaten.
I ended up doing more research today and it would appear I've had anorexia since approx march 2020 (not anorexia nervosa)
"A person diagnosed with anorexia nervosa may feel hungry but restricts food intake. When you have a loss of appetite (anorexia), you don’t feel the need to eat food because you’re not experiencing the feeling of hunger."
Due to being ill at the time, not hungry, and not well enough to cook or properly look after myself, it became normal to eat too little
then there is this ...
"Lack of food causes your body to conserve energy by reducing its metabolic rate. This slowdown helps the body preserve energy stores, but over time, it can reduce your body's ability to produce the energy it needs to function."
Longer term effects include fatigue, weakness, heart disturbances - I've experienced a lot of those plus other symptoms.
I've probably eaten too little food for a good 4.5 years. I mentioned all my symptoms to doctors but they only ever focus on 1 item in a 10 minute appointment, so it's all been overlooked, and my focus had been on my key symptoms, not what I was eating.
So once again thank you - I am going to mention this to my dietician, I searched for contact details today, but the place I went to is so new it's not fully integrated into the system. I shall have to drive over there tomorrow and pop into reception.
And hey I'm ok folks, like I posted yesterday, I can shift bits of furniture solo, so I'm not frail or anything, my main issue is crashing and burning if I try do too much. I'll try get out and do some walking as the weather improves, get some exercise in.
