A week of plant-based meals, planned for you.

The food part is a smaller change than most people expect. At the store you grab a plant protein in place of meat and soy or oat milk in place of dairy. The rest of the cart barely changes.

What makes it feel big is culture. Meat sits at the center of most menus and family traditions, so the first few weeks are mostly about new habits. Once you have a handful of go-to meals, it runs on autopilot.

Easily, as long as you actually replace the protein you removed. The classic mistake is dropping meat and eating the same sides as before. That's when people lose muscle and feel weak.

Put a real protein at every meal (tofu, tempeh, seitan, TVP, beans, lentils or a plant meat) and the numbers add up fast. The people behind PBB eat 180 g or more a day on plants.

Yes. When protein is matched, studies find the same muscle and strength gains on a plant-based diet as on a diet with meat.

The proof is out there too. Olympic weightlifter Kendrick Farris set an American record after going vegan. Patrik Baboumian was crowned Germany's Strongest Man on a vegan diet, and PBB co-founder Joey Bilotich earned his natural pro bodybuilding card 10 months after going plant-based.

No. Soy contains isoflavones, sometimes called phytoestrogens. They're plant compounds, not estrogen. They bind to estrogen receptors weakly and selectively, which is very different from the hormone itself.

The research on men is clear. A 2021 meta-analysis of clinical studies found that soy and soy isoflavones don't change testosterone or estrogen levels at normal intakes.

B12 isn't made by plants or animals. It's made by bacteria. Animals get it from bacteria in their gut or their environment, and most farmed animals are given B12 or cobalt in their feed. Meat is just a middleman.

Modern sanitized food and water mean we don't pick those bacteria up anymore, so take a supplement. Supplement B12 is made by bacteria too, and the form in supplements and fortified foods is absorbed well, which is why it's recommended for everyone over 50 regardless of diet. It's the one supplement every plant-based eater needs.

Yes, when it's planned well. The Academy of Nutrition and Dietetics, the largest group of nutrition professionals in the US, says well-planned vegan diets are appropriate for every stage of life, including pregnancy, infancy and childhood.

Well-planned is the key part. Kids need a reliable source of B12 and vitamin D, plus iron, calcium, iodine and omega-3 from food or supplements, and enough calories and fat to grow. Tell your pediatrician your plan so they can track growth and check iron.
