I’ve been eating a high fat, very low simple-carbohydrate diet for months. Something along this line:

I eat all that I want any time that I want. This isn’t a calorie restriction diet. Although I haven’t bothered to measure it my calorie intake has to be much higher than what it used to be. I eat all the fats, protein, fresh fruit, and fresh non-starchy vegetables that I want. I just avoid as many sugars and starches as possible. The only bread I use is sprouted-grain, which is kind of dry so I’m not inclined to eat too much of it.
I have a physical job and this diet keeps my energy level high. I don’t get hungry. My weight is stable, waistline is smaller, clothes fit better. Eating simple carbs makes me fat, and eating fats seems to make me lean. Go figure.
I avoid low fat foods. For a snack I’ll take plain, whole milk yogurt and mix in some half and half or whipping cream to boost the fat content. Chop up an apple and eat it with some high-fat cheese. I’m sure the low-fat crowd would faint in horror, convinced that this would kill them as fast as strychnine.
The last time I had blood work done everything was great. Cholesterol was on the high side, but that is mostly because my good cholesterol is very high.
I’m glad this works for you. The exercise is important. If you had a less active life, you would probably need to reduce the fat content a little.
