Too tired to cook. Too easy to open a packet. It’s not our fault we eat junk

If this is you, then take a moment and empathize with yourself. If you realize that your situation can't be helped then embrace opening packets and not feeling guilty about being unable to cook. Once you let go of the guilt, your inner engineer takes over and you can optimize which packets of food to buy.

You'd be surprised that there are many healthy options for food from a packet out there such as Soylent, Huel etc. I for one have embraced Huel's hot and savory suite of meals and I've optimized/replaced at least one meal a day. It's healthier than what I'd cook, cheaper than what I'd cook, much much faster than what I'd cook and I've become leaner for free.
