I bought some Isopure Low Carb Protein Powder Dutch Chocolate shake a couple of weeks ago.
It tastes OK, and does keep me full; well did after the second attempt, when I found the scoop inside the bag and realised it was the size of about 5 teaspoons, which was what I’d used the first time and felt generally unimpressed and hungry.
But my general feeling is that a meal is something I eat, and a drink doesn’t really count (I am a bit the same with soup).
I also think that using real food, cooking and experimenting, even just getting a feel for weights and portion sizes, helps educate and better prepare you for eating out, post 800 cal.very low carb (for lots of us that is way more than 8 weeks) – and ultimately be an incredibly important part of the journey to having a better relationship with food.
There’s also all of the research that you’re better off eating the whole fruit than having juice, so would be wary of relying on home made shakes too much.
A colleague did really well earlier in the year with a non BSD meal replacement diet – she has kept the weight off, but does have to keep reverting to the shakes from time to time, because the plan didn’t seem to have a post diet plan (clever marketing, keep you hooked!), and when she is an “eating food” phase, does make some odd choices.
So, the shake is something that I may occasionally grab for breakfast if I oversleep, or carry a scoop with me if I think I may need a meal on the go and don’t have time to prepare a salad and am a bit dubious about access to BSD friendly shop or restaurant options, but I honestly think real food is the best way to go.
