Re: I really don't see the point
The point is that a bland, more expensive, harder to prepare, powder that must be shaken into a gloop isn't a replacement for those things. Even if you're time poor there are better choices.
More expensive? TFA says between £1.30 and £1.60 a meal. I'm about to pop out and buy a sandwich, salad or hotpot for lunch, which will cost between £4 and £8. Dinner tonight is a diet M&S ready meal and some fresh veg, £4.
Harder to prepare? Measure, pour, shake well, drink. Fetching and retrieving the sandwich takes at least 15 minutes, queuing up in M&S at least 5.
"Bland gloop" - I'll give you that one.
The main thing I have against these sorts of food replacements is that they will never be an adequate replacement for food, so eventually you will go back to a food diet. Eating this stuff will not help you develop a healthy food diet, so when you do switch back you will overeat and eat the wrong things.
Me and a friend both were trying to lose weight at the same time, we each lost between 30-50kg, me slightly more than him. He lost it by switching to SlimFast for all meals, I lost it by changing my diet to salads and low fat/low carb/low GI foods and reducing portion size. He has subsequently put everything back on after switching back to food (he literally went straight back to Greggs for breakfast and lunch..).
