Remember, the most important factor in gaining muscle is progressive resistance training and proper nutrition.

What should I substitute in if I am lactose intolerant?
If you are lactose intolerant, you can substitute the following in your meal plan:

Instead of milk, you can opt for lactose-free milk, almond milk, soy milk, or any other non-dairy milk alternative that you prefer.

For Greek yogurt, you can choose a lactose-free version or a non-dairy alternative such as coconut yogurt.

Instead of cheese, you can try lactose-free cheese or a non-dairy cheese alternative made from nuts such as cashews.

These substitutes will allow you to still get the benefits of dairy without experiencing discomfort from lactose intolerance.
