Personally, I'm not a huge by-the-book cooker. For my keto/very-low-carb diet, I just focus on certain foods that are in line with the target macros. That means lots of:
- 80/20 hamburger meat
- Fatty steak cuts (e.g. ribeye)
- Fatty fish (e.g. salmon)
- Fatty chicken cuts (e.g. legs/thigh/dark meat)
- Most pork (except lean cuts like loin) e.g. pulled pork, bacon, belly
- Avocados
- Macadamia nuts
- Eggs (particularly yokes)
- All coconut products (e.g. oil, milk, unsweetened flakes)
- Green, leafy veggies that are low in carbs (e.g. kale)
- Green veggies that are high in fiber relative to carbs (e.g. Brussels sprouts, broccoli)
Spices are all good, so a lot of my meals turn out like meaty stir fry-type dishes without the starch and with a focus on adding fats (e.g. coconut oil, olive oil) if needed.
However, you don't have to be fancy. I usually just eat meat and low carb veggies for dinner. For instance, baking a bone-in chicken breast and heating up frozen veggies (lots of great mixes available) or doing a stir fry with chicken or beef and low carb veggies again (don't use packaged stir fry sauce, however since they are mostly sugar).
