My question for those more experienced in this area is:
What well tested, off the shelf, medically regulated products could I buy today that would allow me to eliminate the consumption of solid food altogether - and of those products, which ones are the best value for money?
I really can't be bothered doing all the leg work required to make my own meal replacement drink (reasons being: the chance of not measuring correctly + work + forgetting nutrients + risk) - I'd like to just grab a product every month or so and just go.
