There’s a lot of different nutritional info when it comes to varieties of milk, both plant-based and dairy. For example, oat milk has a high carbohydrate content in comparison to some other plant-based milks, whereas soy milk has a lower carbohydrate content.
All milks are all counted as a protein. We recommend splitting your protein serving of milk with nuts and/or seeds if the plant-based milk is lower in protein.
Since some plant-based milks are higher in carbohydrates, it would be wise to notice if it slows weight loss. If it does, you could stop using it or split the protein in half and make up the other half with another less dense protein choice.
