Yup, both. Lard as well. Look for fatty cuts of meat. I love eating bacon, marbled steaks, chicken legs, etc. If there's fat on the meat, keep it. Also don't be afraid to cook things in butter, coconut oil, olive oil and lard. This is where the majority of your calories should be coming from.

If you are eating conventional meats, then be aware that the fat in those meats are not that healthy.

This is true. Toxins are stored in the fat, so try to stick to grass-fed/free range/organic meats.
