I'm doing keto for the second time. I can testify it's really hard to eat a low(er) fat diet on keto. I'm lucky because my genetics help me in the cardiovascular arena. However, I do take Ally (Orlistat 60 mg) as a supplement to reduce the absorption of fat and I also take a mega dose of generic Metamucil every night (32g) to help with cholesterol and potential side effects of the Ally.
I tried out a new "recipe" last night that was awesome. It was a 4.5 lb pork shoulder, deboned and fat trimmed, cut into 1-1/2" pieces, cooked in a crock pot on low for 8 hours with a 16 oz jar of green salsa and a Kinder's Chile Verde seasoning packet. I ate 7 oz and it was a little over 200 calories, 33g protein, 8-10g fat, and 0 carbs. It was really good and makes excellent leftovers. Transparency: it probably wasn't actually 0 carbs because I added some corn starch at the end to thicken the sauce.
If you're like me and need some snacks or a sweet fix every now and then, chicharrons are an excellent alternative to chips with 0 carbs, and the Russell Stover sugar free candy is virtually identical in nutrition and portions size as the Atkins treats, but at less than half the cost per piece.
I haven't eaten rice in two years because it's the carb devil, but I have taken a real liking to roasted cauliflower. Some people hate the cauliflower thing for keto, but roasting it with some olive oil and your favorite seasoning can make it really nice. I like to put chicken tikka and rogan josh over it. I also put queso on roasted cauliflower and broccoli.
Each week I grill 5-6 lb of skinless chicken breast and keep it in a container in the fridge to use as quick meals or even snacks if I need to get my protein up for the day. I like to use different seasoning blends to keep it interesting.
ETA: If you're tracking your foods, it's important to either use a tracker that adjusts for NET carbs, like the Atkins app, or one that allows you to manually edit the carb counts to adjust for net carbs.
