I just started using drink wholesome. I like it because it is made with real foods, and has no additives. I drink it with almond milk as a meal replacement (It's very filling!). Hands down the best tasting protein powder I have ever used. Hope this helps!
I use it very rarely and usually only around the times I do any weight training. I don't use it to lose weight. I track all food and make sure the protein range is good. If I get hungry at night I will try to incorporate something healthy like low sodium cottage cheese, yogurt, cheese, or milk to help keep my hunger down.
Protein powder can be helpful as it helps to stave off hunger, perhaps because it helps keep blood sugar stable (so do fat and fiber). It's also very convenient if you don't have time for a regular meal. Still, it is not something I depend on every day, but it's very helpful at times and I always have a few canisters of whey and a pea protein or other vegan protein in my pantry.
It's also helpful in retaining muscle, and generally low calorie depending on the brand and what you may add to it yourself.
