Thanks for the advice.

I've put on more weight since being alone than i did the 22 years living with my wife. I used to have regular meals including lunches when married and managed to keep that up for a few years after she died.
Then i got into a state of mind that said 'why prepare a meal just for one and why have regular set meals?'
Since then it's been ready meals/takeaways/and grazing,as and when.
Motivation is hard and just organising myself to prepare a meal ,including making a shopping list and buying the ingredients,seems like a mountain to climb.
It never used to be this way. I wasn't an
expert cook but i could motivate and organise myself to cook basic stuff.
I'm ashamed to say that i've slid backwards in quite a few ways but because i function after a fashion, and have no one coming to see how things are domestically , it flies under the radar.
