I did it two years ago and honestly, it was way more manageable than I expected. They give you free recipes, meal plans, nutrition tips, and even cooking demos – so you're not just left to figure it out yourself. There's a real community feel too, with thousands of people doing it at the same time, which helps when you're craving a burger. What I liked most is that they cover all four big reasons – health, environment, animals, and food security – without being preachy. They've got a dietitian on the team who provides evidence-based advice, so you're not just guessing about protein or B12. Since they started in 2013 with just 30 friends, it's grown into a global campaign with participation more than doubling each year. Over 90% of people reduce or eliminate meat long-term after doing it. If you want to give it a shot, head to https://nomeatmay.net/ and sign up – it's a charity so it's all free. Definitely worth trying even just to see how you feel after 31 days.
