If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
The Paleo Diet: Eating like your ancestors doesn't guarantee you'll lose weight. While the diet emphasizes plenty of foods that are good for weight loss, such as lean protein and fruits and vegetables, you would still need to eat fewer calories to drop a few pounds. So if you're binging on nuts and fruit, you could actually gain weight on the Paleo Diet.
The Vegetarian Myth: Food, Justice, and Sustainability by Lierre Keith is against industrial farming. She spent 20 years as a vegan, and now reveals the risks of a vegan diet, and explains why animals belong on ecologically sound farms. And as all the neolithic foods we avoid are produced on industrial farms, she is against the foods we avoid. Here's a well thought out review by Eric Wargo: Clubbing Vegetarians Over the Head With the Truth.
It’s easy to find more guidance online, but a book also makes a handy reference. "The Paleo Diet," for example, outlines basic Paleo principles and offers three “levels” that allow for different degrees of cheating – three “open meals” per week on the “entry level” plan, two on “maintenance” and just one on “maximal.” Depending on the level, you might also get “transitional” condiments (low-fat dressing and salsa) and drinks (coffee, beer or wine in moderation) to wash down the meat and plants. You can use the levels as you like. Start with the first and move gradually to the more restrictive – or just stay put. For more dramatic changes, head right to the third.
A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
