Dude, I don't want to preach, but I don't think going no carb is a great idea. Your brain requires glucose to function properly - it's all about the KIND of carbs you eat and how quickly your body metabolizes it.
If you eat carbs low on the GI (glycemic index) it won't spike your blood sugar; rather it will give you a controlled, stable amount of carbs over a long period of time. Of course meats are always low GI, which is why they tell you you should eat meat. But other foods are also low GI. Here are some examples:
Fruit: Nearly all berries, rhubarb, lemons, sour cherries, maracuja, sweet cherries, apricots, limes, mandarine oranges, grapefruit, and pears. Make sure they are fresh, organic if possible, and NO SUGAR ADDED to them. Also decent in moderation: guave, figs, plums, mango, mirabelle, oranges, apples, pineapples, grapes, peaches, and nectarines
Veggies: Spinach, rucola, green cabbage, cress, chard, horseradish, rapunzel lettuce, broccoli, brussel sprouts, fennel, radishes, radicchio, savoy cabbage, black and green olives, artichokes, red cabbage, cauliflower, romaine salad, leeks, sauerkraut, garlic, green beans, escarole, asparagus, kohlrabi, white cabbage, celery, red peppers, Chinese cabbage, carrots, chicory, iceberg lettuce, green peppers, onions, eggplant, tomatoes, and cucmbers
Lentils, sprouts, mushrooms: soy beans, soy milk, ripe lentils, mushrooms (pretty much any kind), soy sprouts, tofu, bamboo sprouts, mungo bean sprouts
Grains and grain products: FORGET IT! Unless the sort-of good grains, like quinoa, whole grain products, but limit as much as possible.
Milk and milk products: pretty much any kind of cheese and sour cream - milk, yogurt, and kefir ISN'T as good as cheese though unless you limit the uptake of the natural sugar with fiber
Any meat, fish, seafood is going to be low GI
Nuts/seeds: pretty much any except chestnuts roasting on an open fire. Especially good: pistachio, almonds, pecans, peanuts, pine nuts, hazelnuts, walnuts, macadamia nuts, cashews, pumpkin seeds, and coconut
Chocolate/sugar: LIMIT!!! But once a week, let yourself have ONE serving of:
- bitter chocolate
- cocoa powder (no sugar added)
- dark chocolate
Juice: NONE!!!!! It enters your bloodstream like a shot of lightning. Except lemon juice in some water. That's cool.
Other beverages: green tea, coffee (in moderation), black tea, fruit tea, herbal tea, peppermint tea, malt coffee, natural mineral water (LOTS!), and water
So you see you have a HUGE choice. Just remember: FRESH! No artificial shit (sweeteners, preservatives)! No sugar added, and feel free to add good oils as a taste enhancer. FAT IS BETTER THAN SUGAR (assuming it is the right fat - with omega 3). Linseed oil, walnut oil, canola oil, and coconut oil are great choices. And SPICES are good for you (LIMIT THE SALT!!!). And add yummy, yummy flavor. Again, just make sure there's no shit in it.
Wrong kind of fat: fucking margarine, partly hydrogenated blah blah fucking blah. These are what are commonly known as trans fats - they take an oil and make a naturally fluid oil solid by adding shit to it. Stay the eff awayyyyyyyyy from that stuff.
If you don't spend money on your health, then you haven't got any right to spend money on anything else.
NEVER SKIP MEALS!!!!!! Your body goes into starvation mode, and you end up gaining more weight. Better to eat 5-6 smaller meals. Oh, yeah, and btw. It fucks up your blood sugar and prevents you from losing weight.
A lot of people think if Calories Burned (B) > Calories Consumed = Weight loss. That is INCORRECT. You are much more complicated that that. You have a lot of hormones and enzymes and triggers that are set off by certain things. According to the B>C = WL method, I should be able to eat 1,000 kcal of chocolate cheesecake in one sitting, starve myself the rest of the day, and still lose weight. Fuck no. If only it were that easy.
The best bet for slow weight loss is consistently good eating and exercise. Who gives a flying fuck what some idiots online think??? Even me. Listen to your doc.
However, you mentioned something about anorexia. I think the whole problem here is if your body is not acclimated to sugar and you pump your body full of it after you start eating again, your body goes HOLY SHIT!!!!!!!! So you have insulin resistance because your body went so long starving without any anything.....
So try introducing low GI foods, and your body will get a SLOW, gradual introduction to sugar again and be able to deal....
Please do yourself a favor and DO NOT pump your body full of artificial sweeteners. These are REALLY AWFUL AWFUL AWFUL for you. Think: rat poison for humans.
