How do you choose a protein powder?

There are so many protein powders with similar labels. I am interested in how people choose between them, especially when the goal is weight loss rather than bodybuilding. Taste and cost matter too, since a product is no help if it stays in the cupboard.
This Ask Ayurveda article looks at the question: choosing a protein powder for weight loss
An article cannot account for everyone’s health history. What do you check on the label, and do you prefer ordinary food instead?x3aMFw
