Which Ensure is formulated to replace food entirely? As far as I can tell, if I drank enough ensure to get 2400 calories, the other nutrients would be out of wack. As in, a given portion does not have the same DV% of each nutrient.
I'd never heard of Fortisip but from what I can tell it and ensure are both considerably more expensive than regular food, and actually more expensive than eating out.
To be fair, $65 is the pre-order price and includes a shaker bottle (worth $10) and free shipping.
Looking at the nutritional info if I drank 6 bottles of Ensure Plus each day I would be ingesting 360% of the recommended amount of Manganese and only 60% of the recommended amount of sodium. The rest of the listed nutrients would be at about 150%.
I don't think Ensure Plus is a substitute good for Soylent. It's a supplement not a food replacement and it's formulated and priced as such.
EAS Myoplex? There are a myriad of other Meal Replacement Powders on the market that has been around for decades, some of them designed to completely replace meals with specific ratios such as 40/40/20 (protein, carbs, fat) or more commonly, low-carb versions. Seriously, go to bodybuilding.com and look under the meal replacement category and you'll find a bunch of products that has figured this shit out decades before soylent.
