I've been vegan for about tenish years.
In that time I've eaten healthily, very unhealthily, been very over weight, been a healthy weight. Currently I'm healthier than I've ever been. Being vegan is not a weight loss diet I hate it when people think that.
I don't usually take supplements (I have during pregnancy and breastfeeding, iron and b12) all my nutrient levels are perfect (I have regular blood tests because I have a hereditary condition which is actually massively benefitted by eating a plant based diet) because I eat a variety of foods fortified with the nutrients we need. My macro intake could probably best be described as moderate carb, low to moderate fat, moderate to high protein (used my fitness Pal so often it's basically built into my brain!)
On a day to day basis I eat things like tofu (in various forms, it's a wonderful versatile food when you know how to use it) tempeh, mushrooms, chickpeas and other beans and pulses, all kinds of veg (especially broccoli spinach kale carrots peas) salads, not very much fruit, brown rice, pasta, peanut butter, chocolate, Marmite, plant milks, occasionally meat and cheese substitutes, avocados, nuts. My meals are not dissimilar to anyone elses really, roasts, sandwiches, curries, chilli, pasta dishes, stir fries, cooked breakfasts, pizza, burgers, chips (rarely these days)
Tonight I'm having fajitas. I had salad with fried mushrooms and green beans with home made houmous for lunch and peanut butter toast and coffee for breakfast. Oh I also had a milkshake. And an orange. It's not really a big deal.
No I don't really talk about it. No I don't care if you don't want to be vegan, you do you.
