I've been watching my fat intake, trying to increase its proportion of my total calories while reducing protein. I've been low carb for a while, which has been very helpful in making me more aware of when I'm actually hungry, as opposed to hypoglycemic. Today I'm up to 65% fat, 25% protein, 10% carbs (~2000 calories total). Feeling great even though I'm at a calorie deficit, leaning out but completely satiated. Just got my lipid panel back this week, cholesterol numbers are perfect. I try to eat fatty (organic/grass-fed if possible) meats, lots of (omega-3) eggs, and plenty of (rBST-free) heavy cream in my morning coffee. I eat a big salad every day with plenty of olive oil-based dressing (barely sweetened with honey). I also take a concentrated fish oil supplement, vitamin D, and glucosamine.
Fat makes you full, research exonerating saturated fat is coming out daily, for example
