In general, we do not recommend having protein powder in place of any of your main meals.
Supplements are a great way to help you reach your goals, but they should be just that – a supplement to your diet. If you have protein powder alone for any meal, it will likely not keep you satisfied and energized for very long. However, you can definitely use protein powder as part of your meal. Think of it as a meal supplement if you'd like, instead of a replacement.
Your Gainful protein blend will supply a lot of high quality protein. This leaves room for you to include other foods in your meal. If you think of the powder as the protein source for your meal, you can focus on including other food groups in there like fruits, vegetables, grains, and dairy for example.
Another great way to do this is by making a protein smoothie. Protein smoothies are a convenient, delicious, and complete meal. Blend up some fruits, veggies, oats, peanut butter, milk, or yogurt with your protein powder and you're good to go! This will give you a good variety of nutrients to keep you feeling full and energized.
Otherwise, you can simply include your protein powder somewhere within your day (doesn't have to be with or at a meal), and also focus on making good choices with your other meals.
