I'm looking for diet shake recommendations. I'm wondering if they're really effective for weight loss and nutritional supplementation.

There are so many diet shake products these days. I think there used to be only a few brands, but now there are so many flavors and meal replacement products that it feels like there are so many choices. But I've never really tried one, so I'm honestly having a hard time deciding. ㅜㅜㅜ

When I read diet shake recommendations, I often see claims like they keep you feeling full longer, provide nutritional support, and aid weight management. I'm curious to see if they actually work. I'd also like to know if changes occur in a short period of time, or if it takes several months of consistent use to see noticeable results.
I'm especially curious about whether you'll actually feel less hungry when you eat it instead of a meal. It also seems important to make sure it contains enough essential nutrients like protein and vitamins. I'm worried it'll be pointless if it just makes you feel fuller.
Are there any diet shakes you've tried that you'd recommend? Please recommend them based on taste, satiety, and long-lasting effects. It would be incredibly helpful if you could share honest reviews, not just advertising!
