I'm not advocating it but as a general point of information, some vegan low carb people are eating lupin-based products because lupin is relatively high in protein (up to 40%) and dietary fiber (30%) low in fat (6%) and contains little available starch; it has very low glycemic index (GI).
The
Vegetarian Butcher in Hague was originally a standalone shop but its products are now available in many parts of the NL: their products were substantially based on lupin and originally most vegan. As they're meat free products that taste like meat, feel like meat, look like meat, they're more targeted at people who wish to reduce their meat intake than vegans.
ETA: Just checked. Disappointingly more of their products are now vegetarian rather than vegan and more of the range now includes soy as well as lupin. In fact, lupin seems to be in the minority but there are still items such as

In Germany, there are lupin milks and ice-creams available in some areas for people who are dairy intolerant: Lupinesse range
