Well if it is only 1g/carb, then it isn't meant to be a meal replacement and is probably pretty light on calories for a meal unless you are eating more than 3 times per day?
I'm not a fan of whey protein powders but I also don't like eating in the morning. I get hungry in the morning but I prefer to drink my breakfast so I mix a protein powder (my current favorite is PlantFusion which is also not meant as a meal replacement) with fruit to make it more of a meal. Depending what I add, it is 250-300 calories and has a nice mix of protein, carbs and fat. If I do buy a meal replacement powder, I tend to scale back on the fruit a bit and don't need to add any fat but I like the mix of frozen fruit with my protein powder.
I really like hemp, brown rice and pea protein mixes overall but they can be a little gritty due to the hemp but I like the healthy fats and fiber that generally come in hemp protein powder.
You can't out-exercise poor eating habits.
