Well, that wasn't a really, really low carb meal.
Leave the fat on the bacon. Fat is good.
Avoid the slice of bread, because bread is not low carb.
The tomatoes are O.K. at about 6 grams of carbohydrate for half a tin.
Not bad for a first attempt.
If you avoided the bread and added in a bit more fat then you would be getting there.
Fry the egg in butter instead of poaching, for example.
You are getting the idea of low carbohydrates but I think you may be still suffering the memories of "healthy eating" advice where you cut the fat off meat and poach an egg instead of frying it to avoid those deadly fats which make you fat. Also noted that you grilled the bacon, presumably to reduce that awful fat.
The idea of low carbohydrate eating is to replace the carbohydrates with other energy sources, mainly fat.
The fat also helps to slow the absorption of carbohydrates and reduces any post meal BG spike.
Don't be discouraged. 8.8 after 2 hours isn't a disaster and your results may well improve as you settle into LCHF.
