Eat generous amounts of saturated fats like coconut oil and butter or clarified butter. Beef tallow, lard and duck fat are also good, but only if they come from healthy and well-treated animals. Beef or lamb tallow is a better choice than lamb or duck fat. Olive, avocado and macadamia oil are also good fats to use in salads and to drizzle over food, but not for cooking. For more information, have a look at our beginner’s guide to Paleo and fat.
Another 2014 study in the European Journal of Clinical Nutrition compared the effects of the Paleo plan to those of a standard low-fat diet on 70 obese, postmenopausal women. After six months, the Paleo group lost 14 pounds on average, while the other group lost nearly 6 pounds. After a year, the Paleo group had lost 19 pounds on average, and the low-fat dieters had dropped 10 pounds. A year later, both groups had regained some weight: The Paleo group was still down 10 pounds, while the low-fat group had dropped an average of more than 6 pounds.
According to Adrienne Rose Johnson, the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Dr. Emmet Densmore and Dr. John Harvey Kellogg. Densmore proclaimed that "bread is the staff of death," while Kellogg supported a diet of starchy and grain-based foods. The idea of a Paleolithic diet can be traced to a 1975 book by gastroenterologist Walter Voegtlin,:41 which in 1985 was further developed by Stanley Boyd Eaton and Melvin Konner, and popularized by Loren Cordain in his 2002 book The Paleo Diet. The terms caveman diet and stone-age diet are also used, as is Paleo Diet, trademarked by Cordain.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds. https://www.youtube.com/watch?v=g5n68qEhqIM

Whether you’re a longtime primal-eating fanatic or just curious about what it’s like to go back to dietary basics, we’ve got 39 delicious Paleo-approved snacks for whenever hunger strikes.
Nutella might seem like a healthy alternative to most treats, but it is actually packed with sugar. This fantastic recipe uses the concept of combining ground hazelnuts with chocolate flavoring, but it cuts down on the crazy amounts of sugar in store-bought Nutella and uses cacao powder instead. If you want to use this homemade Nutella to make a healthy paleo snack, you can use it as a dip for fresh fruit slices. However, it is also excellent as a decadent filling in paleo cakes or cookies.
