I follow a “low carb, high fat” diet. This means that I restrict my daily intake of carbohydrates to 20 or 30 grams net per day (fiber grams are subtracted, so the total carbohydrate grams is more like about 40). I eat an adequate amount of protein, and the rest of my calories come from fat.
In addition, I do not eat any grains at all, and I limit the carbohydrates I do eat to non-starchy vegetables and low glycemic index fruits (mostly small servings of berries and occasionally melon). Whenever possible, I seek out organically grown foods. I eat starchy vegetables (potatoes, sweet potatoes, winter squashes, etc) very occasionally. I do not eat any sugar, syrup (including agave). I eat a very small amount of Splenda (Sucralose) and Stevia (in the pure, powdered form). Most of the foods I eat are unprocessed.
And yes, I eat “high fat”. I aim to get about 70% of my daily calories from “good fats”–good fats may not necessarily be what you think of as “good fat”. I don’t eat any hydrogenated fats, but I also try to limit and avoid industrial seed and nut oils (soy, corn, peanut, vegetable, etc). I do eat real butter and ghee, coconut oil, olive oil, small amounts of cold expeller pressed canola oil, and animal fats. I try to get my animal fats and proteins from “clean” animal sources–animals that have been pastured and given their natural diet, rather than grain-fed, in the form of full-fat meat, fish, eggs, some cheese, whole fat dairy, organ meats, and even rendered animal fat (in my case chicken fat schmaltz).
I don’t count calories, and I’m not afraid of raising my cholesterol from this Way of Eating. Study after study shows that it is carbohydrate, not dietary fat, that causes us to have “bad” cholesterol and to gain weight. Dietary fat is essential to human health, it helps me eat less by keeping me very satisfied, and it tastes GREAT!
