Those who are thin and have trouble getting enough calories on a low carbohydrate diet can eat plenty of nuts and seeds. They are high in protein and high in calories, yet very low in sugars and overall carbohydrates. I used to be able to eat peanuts, but now can't tolerate them. Peanuts often have plenty of mold, and in general many people are sensitive to them. At least I can eat other nuts and sunflower seeds. I also gave up fruit, and eat low carbohydrate vegetables instead(no potatoes, corn, sweet potatoes,peas, etc.) I used to be around 40 pounds overweight. Now I am at a good weight, and don't want to lose much more weight.

For those who are nursing, I can't see how B vitamins could be harmful in reasonable dosages(perhaps 50 mg a day or less of each?, Around 50-100 or so mcg of B12?), and would probably be beneficial to the infant. It would be better to take a B vitamin that has niacinamide rather than niacin, since some people get a very uncomfortable flushing feeling when taking the niacin form. It is not dangerous, but may make their face red, and cause plenty of sweating. Not fun. I had this a few times. Some of the more powerful antifungal herbs should be avoided while nursing. Things like clove oil, oregano oil, wormwood, and the other parasite cleanse herbs should be avoided while nursing. Imo it is probably best to even limit the amonut or raw garlic eaten while nursing.
