Ok looks like air for me since I can’t get my brain round planning meals without carbs
It is different to what has been drummed into us as "healthy eating" for years, but it is actually quite easy
1. Pick a protein, meat, fish, eggs
2 add low carb veg (thats salad, cabbage, kale, celery and many more)
3 add a good fat, olive oil in dressings, lard for frying, cheese or cream into a sauce
The only fruit is a very few berries, strawberries, blueberries, raspberries
Use full fat versions of yoghurt instead of milk.
Add nuts and seeds if needed, or just a few as a snack
I use a very friendly site called keto fitness club for recipe ideas
www.ketofitnessclub.com
Or diet doctor is good, especially for learning what is high or low carb
www.dietdoctor.com
You'll get there, it took us time too
