If you prefer a simpler approach, whey protein concentrate is a good middle ground. It has more calories and fat than whey isolate, which helps with weight gain. Casein protein is another solid choice because it digests slowly, providing a steady stream of nutrients. Just make sure to pair your protein powder with a high-calorie diet and strength training to see the best results.
