Some things that have changed in the past year or so about how I deal with fat (the macronutrient/substance, not adipose tissue): I cook with butter now. I switched to full-fat yogurt, which I sometimes spice and top with a drizzle of straight olive oil, grassy green and peppery. I gave up my oil-free moisturizers and cleansers and put jojoba oil on my face, straight, and have stopped washing it with soap. I take a cod liver oil supplement that's nothing but fat. I put heavy cream in my coffee. I order cream soups. I keep mayonnaise in my house. I generally choose ice cream over sorbet (except when heat relief is the goal, or when there is a particularly good grapefruit sorbet). I do not try to put the minimum of dressing on my salad. I order (and sometimes prepare at home) bone marrow, and eat it with great gusto. I never eat an egg white without the yolk that belongs to it (except in some egg white-requiring preparation: meringues or cocktails or whatever). I save my bacon grease for cooking (caramelizing onions, roasting brussels sprouts). I produce bacon grease in the first place. When I was working on normalizing fat consumption, I think I went through three pounds of bacon a week, the big Wegman's store-brand packages. These days, I eat red meat several times a week, up from maybe a few times a month. I order grass-fed, humanely raised meat in 20-pound packages from a farm upstate (the more fat I eat, the more conscious I become of its quality). I buy beef and chicken livers from Fleisher's in Park Slope. Chicken livers fried in butter has become my favorite breakfast; the first time I made them, dubious, I hopped around my kitchen making noises after I put them in my mouth. When I get a latte at Starbucks, I specify that it should be made with whole milk.
Some possible effects: my cast iron skillets are beautifully seasoned; my skin looks better than it has since puberty; my nails aren't brittle anymore. I can also say with relative confidence that the radical increase in my fat consumption has some relationship with my increased satiety and decreased food anxiety.
