Because protein contains very satiating calories, it can make a lot of people feel quite full when they increase their daily amount. If you're struggling to get your recommended intake, you might want to consider using a protein powder as this could eliminate any extra and unnecessary calories for you. Another option is to make use of a regular exercise routine as physical activity will increase your appetite! If you still find that you're struggling, don't hesitate to take a step back and reduce your protein intake to what is comfortable for you. Making substantial changes too quickly to your body can overwhelm it. If you gradually increase your protein intake, you might find it easier to maintain until your body has time to get used to your new dietary lifestyle.
