You donât have to go whole hog from day one. You can phase into it slowly. Start by cutting out all sugars and refined carbs. Replace them with healthy low-carb veggies. Increase healthy fats and protein. Work your way into it.
You donât have to buy super-expensive foods. The veggies are so cheap itâs like they give them away. Skin-on chicken is not that expensive. Butter. Olive Oil. Real cheese (not the fake stuff). Raw unsalted nuts (almonds, pecans). Full fat whipping cream.
You can have full-fat plain Greek yogurt in reasonable quantities. Fage is a good brand for that. Full fat cottage cheese, sour cream also ok, in moderation and keeping an eye on total carbs.
Only place that will hit your wallet is the meats and especially fish. I bought a nice piece of sirloin steak the other day that was about $6, which I could probably have stretched into two meals. Ground beef is fine, and not that pricey. Chicken is usually affordable. Doesnât have to be skin-on either. I use boneless/skinless sometimes just for convenience.
Sliced deli meats - chicken, turkey, beef, ham (watch out for sugar or maple cured hams) - no cooking required. Make no-bread sandwiches: meat, cheese, mayo, lettuce, tomatoes. Eat with a fork or roll up in the lettuce.
Does seem to work better with a lot of cooking, though. That is something I am dealing with as well - I am spending a lot more time in the kitchen.
However, that is exactly what you really need to do to eat healthy. Prepare your own foods from fresh ingredients, where you control what goes into them and the portion size.
The trick is to figure out how to fit that into your schedule.

Also: Drown your hunger. Water, green or black tea, black coffee or with a little heavy cream. Lemon or lime infused water is one of my go-to drinks. Has just enough flavor to it but not enough juice to worry about the carbs from. Anytime you get hungry, drink water. For me, I had to abandon diet sodas or anything with artificial sweeteners.
The first week is a tough slog. I did have to run on willpower and commitment for a couple of days. Once ketosis kicks in, it is like a wind at your back. Some days, I have to remind myself that itâs time to eat, and I can listen to my empty stomach growling without actually feeling hungry. For me, that is the real benefit of ketosis. It is like a natural diet pill, without the pill.
