A review in ''Publishers Weekly'' commented that "''Pegan'' is a silly, paradoxical misnomer: no diet can be simultaneously paleo (meat, fats, and few vegetables/fruit) and vegan (with no animal products whatsoever). However, the diet’s recommendations are basically sound: fresh, locally sourced, preferably organic food; nothing refined or processed; and a focus on not raising blood sugar."<ref>[https://www.publishersweekly.com/978-0-316-33886-8 "Food: What the Heck Should I Eat?

Dietitian Carrie Dennett has written that "while the pegan diet is more moderate - and potentially easier to follow - than either of its dietary parents, it does restrict many nutritious foods for reasons that aren't quite supported by science."<ref name="Dennett 2019"/> A downside to the diet is that it can be costly for those with low incomes who cannot afford the expensive "grass-fed" and "pasture-raised" animal source foods that Hyman recommends.<ref name="Dennett 2019"/> Aisling Pigott, a dietitian and spokesperson for the British Dietetic Association, has suggested that the pegan diet is too restrictive to maintain and although some of its principles such as eating more plant-based foods and fewer processed foods are recommended for good health, "labeling this as a 'diet' is unethical and potentially dangerous and difficult to follow."<ref>Muzaffar, Maroosha.

Dietitian Alyssa Pike has disputed Hyman's claim that gluten should be avoided by people without a gluten allergy or intolerance and concluded that "the concept of this diet, combined with its number of restrictive rules, will likely make it hard to follow long-term and add to confusion about what to eat and why."<ref>[https://foodinsight.org/what-is-the-pegan-diet-vegan-paleo-mashup/ "What is the Pegan Diet?"].

Oncologist Adil Akhtar has commented that "the pegan diet has taken good things from the vegan diet and attached it to some of the good things from the paleo diet. Both of them emphasize eating whole, natural foods, and avoiding eating anything processed or anything artificial. If you look at the pegan diet, it's about 75% vegan. The only difference is the source of protein in the vegan diet. Vegans get protein from beans and legumes. On the pegan diet, you're allowed to tap into grass-fed, healthy animal meat".<ref name=USNWR>{{cite news |last1=Howley |first1=Elaine K. |title=What is the Pegan Diet? |url=https://health.usnews.com/wellness/food/articles/what-is-the-pegan-diet |work=U.S. News & World Report |date=July 3, 2019}}</ref> Akhtar has noted that the pegan diet "looks quite close to the Mediterranean diet" and may be helpful to those who want to reduce their risk of developing cancer.<ref name=USNWR/>
