I have recently been asked on quick breakfast or on the go type meals that would be easier for someone who has a busy schedule. I recommend getting a protein powder. The one I recommend most is Royal Whey Protein Isolate, it has no sugar, no cholesterol, no soy or genetically modified products. It can be used to supplement up to 2 meals. The best thing about this protein powder is there are a variety of flavors to choose from and one can control the amount of sugar and calories he or she wants by having control over the ingredients being used.
It can be blended with water, oats, almonds or nuts, almond milk, berries, peanut butter, kale, greek yogurt, etcetera; with all sorts of combinations it gives one a good variety of options to have a healthy meal replacement. I like to use the protein powder with a 1/2 cup of almond milk unsweetened, frozen mixed berries, ice, banana and a scoop of peanut butter. I've had it with just water, oats, almonds as well with ice to give it more of a thicker consistency. It's delicious and filling.
It is better to make your own shakes and take them on the go than buying the ones pre-made at stores or through alleged nutrition and weight management companies like herbalife. The best way to tell if they pre-made shakes are good is to look at the ingredients list. They list the higher concentration ingredients first then it gets lesser, if one looks at the first two ingredients and either of them end in -ose, like glucose, sucrose, or any form like that means it is sugar. Most of the pre-made shakes have sugar as their main ingredient which is bad for you. Also, those shakes do not contain enough calories for one to have a healthy calorie intake to be considered a meal supplement or replacement.
It is always good to have a meals at least 300 - 400 calories for one to eat the proper amount of calories before the body's metabolism slows down to starvation mode, which the body will store fat and burn muscle, which is the last thing anyone wants is more fat.
If you are on a weightloss journey and are trying to change to a healthier lifestyle, I definitely recommend a protein powder to use as a meal supplement or even as a recovery from an interval training workout.
