When my DH and I started on this it blew our minds. I was raised to think "bacon=bad" and was raised on a very low fat, high carb diet. You will need to work through a new mindset; that more than anything helped me accept this WOE- how I think about "healthy" foods. Now: carbs hold no sway over me as they are now trash foods. Like @dragonwolf said, not fit for human consumption.

I'm going to say that if you adopt the mindset that carbs are an addiction for you, and treat all carbs like an alcoholic or heroin addict would treat their substances while trying to quit, that it would serve you well.
If you could go cold turkey into a zero grains, starches and sugar plan, staying under 50g a day (personally I think aiming for 20 would get you past withdrawal faster but I'm trying to not be too hard core on you), and avoid eating any of the low carb sweets and artificial sweeteners you'll find all over the place, that within one week, you will be amazed at the way your body responds. And that after 2 weeks, you will not be relying on will power to keep you from eating those foods you once loved, because the metabolic process that always tells you that you NEED those things will start to adjust and the call will fade into the background.
It's really important to know that there's a cause and effect that drives carb cravings. You can take control of the cause and eliminate the effect. One you make the switch in your body, it's no longer mind over matter. You will have to start out relying on will power though. But you can do it! You deserve it! You deserve to feel good and healthy and strong! And you absolutely can get there and start feeling that way as soon as a few days in. It will only get better and better as you continue too.
Some tips to get you started

1. You will need to forget all the dogma associated with eating fat and salt. You NEED FAT AND SALT. It's absolutely vital to your success on a low carb diet. You need more salt on low carb because your body doesn't hold onto water. Any inflammation you currently have will go away and you'll lose lots of water from it and by using up your stored glycogen. Getting low on sodium leads to other electrolyte deficiencies too.
2. Instead of thinking about foods you "can't have", think about foods that will lead you into a new healthy life that you love and fit the plan. Bacon? Eggs? Cheese? Good, fatty steak? Butter? What's not to love?
3. Lose any ideas you have about "eating 3 meals a day" and snacks and that certain foods are for breakfast and stuff like that. Eat when you want and what you want (within plan of course) whatever time of day works for you.
4. In your first few weeks, DO NOT COUNT CALORIES. You really don't ever have to count if you don't want to. There's too much that's already new about this for you and lots of adjusting your body will be going through. Do not add worrying about calories to that list. If you want to do it later, after you've gotten the hang of how and what to eat, that is totally fine.
5. READ THE INFO IN OUR GROUP LAUNCHPAD. super helpful stuff in there.
6. Ask questions. Our group is very active and have all kinds of levels of low carb and various different approaches. You'll find its a very supportive environment.

That's all I've got for now since I have to get ready for work (eeek) but you'll get good tips and advice from many others I'm sure.
best of luck to you!

I understand. I am a celiac and very low carb due to insulin resistance, so I had my days of "but what can I eat?" the first few weeks are scary but once you start feeling better and settle into a routine, it gets easier.

My advice would be to do lots of reading. Books that helped me were Dr Bernstein's Diabetes Solution, Wahl's Protocol, the Art and Science of Low Carbohydrate Living, Obesity Code, Wheat Belly and Cholesterol Clarity.

I also liked Jimmy Moore's and Peter Attia's blogs, and Jason Fung's youtube videos. Educating myself made embracing this woe much easier.

My advice would be to drop all grains and GF substitute foods. They'll be high in sugars and starches. No one needs them, we just want them. Avoid all sugar added foods too.

That leaves meats, seafood, eggs, nuts, olives, avocado, full fat dairy, veggies (limit starchy root veggies like potatoes, carrots, turnips, etc) and a few low GI fruits. The first week eating this way takes work but once you start to feel well, it gets easier.

Considering increasing sodium too. Electrolytes often get low when people first cut carbs. Salt your food, drink broth or even sat your water. It helps avoid headaches and fatigue.

Hang in there!

You've already gotten great advice already! Let's take baby steps here. Stop eating bread, pasta, rice and potatoes.

Let me make ordering out a little easier for you.

Jimmy Johns does their sandwich as an "Unwich" - basically all the fillings of a sub wrapped in a few big romaine leaves. You can make these at home too, there's youtube videos showing how to wrap them. I think they use two leaves. This is something I order all the time and I think it tastes better as an unwich.

Mc Donalds - pick off the buns. Ask for extra lettuce and eat the burger like a salad. I'm not sure if they have a lettuce wrap option.

Red Robin - This place DOES wrap burgers in lettuce if you ask. You can also ask for a side salad or side of broccoli. If you do get a salad, pick a low carb dressing, ranch is usually a safe choice. No croutons, no tomatoes.

Subway - Any of their sandwiches can be in a bowl. I like the double chicken salad myself.

I hope this gives you a few ideas. Take it slow and do some reading over at /r/keto on Reddit, their FAQ is great. Don't count calories for now.. get used to this way of eating (WOE) first and don't stress yourself out.

Foods I regularly eat: Eggs, bacon, sausage, big mac salad (romaine lettuce, thousand island, cheese and cooked ground hamburger on top of the salad), whole avocados, cobb salads, broccoli, cauliflower, pepperoni, and LOTS OF CHEESE! Blue, pepper jack, cheddar, mozzarella. A serving of almonds as my snack, or very dark chocolate (90% or over). Most leafy greens are completely fine!

No croutons on salads of course..

Hi @msty112! I'm so glad you're here, and I hope you find the healing you need.

In your original post, you said that your doc wants you to try LCHF at 100g carbs per day or less. Later you mentioned that you're worried about avoiding fruit, root vegetables and beans. You could still eat those in moderation and come in under 100g carbs/day. Is there any other reason you have to give up those specific foods?

Maybe it would be a helpful exercise to list out some low carb options for breakfast, lunch, dinner and snacks that you can live with. Flourless egg muffins for breakfast maybe? Tuna or chicken salad over Romaine or spinach for lunch?

I wish you great health and happiness!

Filling the Cracks with Healthy Fats

Some low-carb gurus recommend setting a limit on carbs and proteins, then filling in the cracks with healthy fats (mostly avoiding polyunsaturated).

I was astonished and delighted to discover that when I started adding fats as crack fillers, lo and behold! - my hunger and snack urges subsided. Wow!

A bakery? That's rough.

Once your palate adapts to the lack of sweet, you may find once intolerable food quite agreeable, especially when generously salted. Give it some time and revisit some of those foods down the road. You might be pleasantly surprised.
