Additionally, the Paleo diet puts a heavy emphasis on meat products. For this reason, the Paleo diet may not be suitable for everyone, and you’re unlikely to find a Paleo diet vegetarian or vegan modification out there. While meat in moderation is perfectly healthy, excessive meat consumption may not be. A high intake of red meat, for example, has been linked to an increased risk of mortality and colorectal cancer.

The Soft Science of Dietary Fat is a summary of an article in Science Magazine reporting that mainstream nutritional science has demonized dietary fat, yet 50 years and hundreds of millions of dollars of research have failed to prove that eating a low-fat diet will help you live longer. In fact, there are good reasons to believe high-carbohydrate diets may be even worse than high-fat diets. Here is the text from the original article by Gary Taubes.
You may notice that the following meal plans do not include any snacks. This is because, technically, snacking isn’t really something you should do while on a Whole30. Just be sure you’re getting enough food at each meal (which may be hard at first as you adjust to eating whole, real food and no processed “foods”) and you won’t need to snack. If you do feel the need to eat something between meals, try to keep some cut-up veggies on hand so you’ve got something easy and quick nearby and aren’t tempted to grab something non-Whole30.
Experts estimate that our ancestors consumed a one-to-one ratio of calories from meats to produce. Since you have to eat a lot of salad to consume the same amount of calories in a steak, the paleo diet should ideally include mostly fruits and vegetables, Katz says. However, many people don't realize that and eat too much meat. Consuming excess protein and not enough carbs can cause kidney damage and also increase your risk of osteoporosis, Dr. Ochner says. Plus, since most of today's meats are higher in saturated fat than those of yesteryear, it can increase the risk of heart disease, Dr. Katz says.
Some specific foods that fall under this rule include: pancakes, waffles, bread, tortillas, biscuits, muffins, cupcakes, cookies, brownies, pizza crust, alternative flour pastas, cereal, or ice cream. No commercially-prepared chips (potato, tortilla, plantain, etc.) or French fries either. However, this list is not limited strictly to these items—there may be other foods that you find are not psychologically healthy for your Whole30. Use your best judgment with those foods that aren’t on this list, but that you suspect are not helping you change your habits or break those cravings. Our mantra: When in doubt, leave it out. It’s only 30 days.
In response to these criticisms, CrossFit, Inc. claims, “CrossFit is relatively safe even when performed with poor technique, but it is safer and more effective when performed with good technique.” CrossFit, Inc. also claims risk for injury can be reduced by properly scaling and modifying workouts, a concept taught on its website and at the CrossFit Level 1 Trainer Course.
Additionally, “while the paleo diet has plenty of protein and fiber, it is sorely lacking in calcium and vitamin D, mainly because of the omission of dairy products,” Roger Adams, Ph.D., founder of Eat Right Fitness, previously explained to Men's Health. Over time, this could weaken your bones and immune system, which makes it important to eat plenty of calcium-rich (and paleo-friendly) foods like broccoli and dark leafy greens.
Primal Blueprint Quick and Easy Meals: Delicious, Primal-approved meals you can make in under 30 minutes by Mark Sisson and Jennifer Meier. Every recipe is accompanied by an ingredient list, a nutrient list, clearly written instructions, and a picture of the ingredients and a picture of the finished product. Note that this is a primal book and many recipes include dairy. Published March 25, 2011.
Anything that comes in a box, jar, or bag should be avoided on the paleo diet—as should anything that just wasn't consumed back then. That means no grains, dairy, added salt, or legumes (including peanuts, beans, lentils, and soybeans), according to Robb Wolf, a former research biochemist, paleo expert, and author of The Paleo Solution. While potatoes are generally outlawed on the diet, Wolff says they are okay to eat sparingly as long as you earn them through exercise (more on that next). Alcohol and honey are also generally considered paleo no-nos, but red wine tends to be the closest option there is to a paleo drink, and honey is far preferred to table sugar or artificial sweeteners.
Gluten is a protein found in things like rye, wheat, and barley. It’s now being said that much of our population may be gluten-intolerant (hence all the new “gluten-free!” items popping up everywhere). Over time, those who are gluten intolerant can develop a dismal array of medical conditions from consuming gluten: dermatitis, joint pain, reproductive problems, acid reflux, and more.
With a very simple shift we not only remove the foods that are at odds with our health (grains, legumes, and dairy) but we also increase our intake of vitamins, minerals, and antioxidants. Here is a great paper from Professor Loren Cordain exploring how to build a modern Paleo diet: The nutritional characteristics of a contemporary diet based upon Paleolithic food groups. This paper also offers significant insight as to the amounts and ratios of protein, carbohydrate and fat in the ancestral diet.
Most of these recipes give us enough dinner for our family and then leftovers for my husband and I (I make a separate lunch for the kids most times). If you both eat normal-sized portions, you would probably be fine to cut it in half and have enough for leftovers. But if you tend to eat larger portions, I’d err on the side of caution and just go with the full amount.
