#1 It depends on what you want to do. If you want to just maintain your health then eating as low as 10% calories from protein sources is enough, which on a 2000 calorie diet is 50g of protein. Most people should be able to easily get that from plant based sources in their diet - if they eat clean, and aim to incorporate protein rich plant sources in each of their meals.
On a vegetarian or a vegan diet, I have noticed it is proportionally easier to eat fat and carbs from plant sources. Especially because I don’t like to eat soy products all that often, such as tofu.
My goal right now is that I don’t want to go down in weight but rather build muscle while lowering my body fat percentage. Vegan protein powder allows me to achieve this more easily. And it helps my body recover after a strength workout, if I consume protein right after a workout session. Most body builders and athletes eat around 20-30% or even up to 40% of their calories from protein. I try to eat 20%-25% of my calories from protein, with no more than 60% of my protein coming from protein powders. That’s about 80-100g of protein a day for me with 17-60g of protein coming from protein powder, depending on my workout schedule.
It really depends on your body too. If you feel tired and sluggish quite often, your body could be needing some extra protein. While other people feel just fine consuming a lower amount.
Vegan protein powder also allows me to get something in me, even if I am not hungry but I know I need to eat something (not as a meal replacement but a snack). When I have a migraine, Im often not hungry and chewing can make the pain worse so a protein shake can help until I can get some solid food in me.
It’s tastes like banana and almond butter! Just as if you were to eat a banana and almond butter toast.
