I thought this paragraph from www.ppnf.org newsletter might be of interest;
If you want to lose weight, eat only 3 meals a day with plenty of quality animal fat and protein.
No snacking or eating starches or sugars! Non-starchy vegetables are good. If you must eat fruit, limit it to 1 or 2 fresh, organic whole fruit per day (no juices). You should be satisfied until the next meal. If not, analyze your previous meal. You may not have eaten enough fat and/or protein. Be sure the animal fat and protein is from healthy animals. The less it’s cooked the more nutrients you will receive. As an added bonus, emotional well-being is gained by ingesting omega-3 fatty acids. These can be obtained from various animal proteins (ex: wild caught, fresh salmon), but when eating beef or lamb, it can only be obtained from grass-fed animals.
