I'm sorry - and I'm trying to be kind here, honestly! - but that's a truly shit diet. No wonder you have no energy!
So today I've had 2 cuppa soups
Full of artificial ingredients, and highly processed, which won't be doing you any favours.
and unusually for me 3 mini sausage rolls
I'm glad this is unusual! Lots of carbs here, not only from the pastry but also, most likely, from the sausage meat
Tonight for dinner I'll have 2 slices of ancient grain bread from Aldi and 3 scrambled eggs
The scrambled eggs are fine, but the bread is adding more carbs - even if it is made from ancient grains.
Yesterday was similar but no sausage rolls and 2 large bananas instead
Bananas are the most carby fruit you could have chosen
and ancient grain blt sandwich with lots of salad and streaky bacon
Not sure how much salad you can really get into a sandwich! But again, carbs from the bread.
You're not eating anywhere near enough vegetables, and your protein is fairly limited. So you'll be eating a high carb diet, which won't be doing you any favours at all.
Were you not given any advice about diet when you were in the run up to/after your weight loss surgery?
