There is no magic formula to weight loss other than burning more calories than you consume. One strategy to minimize calories is by trying to add 4 ounces of Skim Plus milk and some ice in a blender with the protein powder. You can add an artificial sweetener like splenda for flavor and this will limit the calories to a total of 155 calories per serving. It is acceptable to add fresh fruit and make it more of a smoothie. In order to limit calories use 1/2 cup fresh berries. Make sure the berries if frozen have no added sugar. One cup of fresh strawberries sliced is only 50-60 calories. This will keep the shake at around 200 calories.
