These can be smoothies, bars, drinks, supplements, etc.
Is there something specific you look for (ex. price, ingredients, specific nutrients etc.)?
Is there a brand you like / avoid (ex. soylent, huel, hol food, etc.)
Edit:
I definitely don't recommend fully replacing your diet with them. I know some people use them instead of other processed food / fast food / skipping meals entirely, and that's the use case I had in mind for myself
I make very easy shakes in my nutribullet which are just water, ice, oats, chia seed, protein powder with probiotics, peanut butter and some berries or a banana. I swap in some other things like hemp hearts for the chia sometimes.
Tastes great and requires little effort.
For anyone tempted to make this, make sure you soak the chia seeds for a few hours first. They're so thirsty for water they can cause some awful bowel problems otherwise.
Good to know. I haven't had any issues but I drink a ton of water.
Easy to do last thing at night, just chuck the chia seeds in with the water and add everything else in the morning.
They'll keep for days soaking in the fridge so you can make big batches if you prefer.
