❓Is protein really enough on a long-term vegetarian diet, and how should I combine foods?
I've been working out for two years and recently switched to a vegetarian diet. My family keeps saying I definitely won't get enough protein. I'd like to know how to plan my daily meals so I'm actually covered.

Adults generally need about 0.8-1.0g of protein per kilogram of body weight per day, and that goes up to 1.2-1.6g if you exercise regularly. Vegetarian protein sources are actually pretty abundant: tofu, dried tofu, tempeh, edamame, lentils, chickpeas, seitan, quinoa, plus nuts and seeds. Soy products already have an amino acid profile close to a complete protein, so you don't need to carefully pair grains and legumes at every single meal — as long as you eat a variety of foods over the course of a day, your body will piece together the amino acids from different meals on its own. I'd suggest spreading your protein sources across all three meals rather than counting on hitting your target in just one.
I've been vegetarian for almost ten years now. I was really anxious about this exact question in the first few months too, but then I tracked my food with an app for two weeks and realized I was worrying over nothing — with tofu, soy milk, chickpeas, and nuts in a normal day's meals, my total protein wasn't much lower than when I used to eat meat. My advice: don't just speculate, actually log your food for a couple of weeks and look at the real numbers. It's way more reliable than guessing, and a lot of this anxiety doesn't hold up once you check the actual data.
