I've learned a lot for MY BODY on primal, since 2010, and a few things that it's taken a few years to get a definitive stance on, for me, is that: more coconut oil = weight gain, no satiety, increased hunger. More meat= increased weight gain and hunger. I could eat a whole cow and jar of delicious virgin coconut oil in one sitting. It doesn't matter if I eat no carbs, just fat and meat, I'll eat a lot, and get plump. Lean meat+lots of veg = thinner. No meat, lots of veg, 4 tablespoons of fat, give or take=lean. Sweet potatoes, veg, starch, two tablespoons of fat = very lean and full. Now, bear with me, my husband, 6'4, 140 lbs, very thin, but ripped, eats whole meat pizzas, bags of chips, bowls of dairy-laden dip, two-loaves of bread per week, and no fat or weight gain. We are 31 years old. Our bodies are different. I do better on veg, seafood, lowfat, no refined sugar, and he does good on anything! I'd hate him, except, I can wear his cuffed jeans...
