This is my current approach as well. Took me a good 3 weeks for my digestion to adjust though to liquid meals 2x a day so be prepared for that. I've managed to lose around 5lbs the last month so seems to be working. I tried fasting but it was too hard to stick with, so the huel shakes for breakfast/lunch seem like a much more sustainable approach. And you still get a nice meal every day. Only drawback I find is with being in the office again - I am sorely tempted to get a hot meal with coworkers.
