Excess Protein May Cause Digestive Symptoms and Stall Fat Loss
Protein helps the body build muscles and support important functions.
But eating much more protein than needed can cause problems for some people.
If protein replaces fruits, vegetables, and whole grains, constipation or bloating may occur.
Very low-carbohydrate, high-protein diets can cause bad breath and make people thirsty.
Not drinking enough water may lead to dehydration.
Some dairy proteins can upset sensitive stomachs or worsen acne.
Cutting carbohydrates too much may also cause tiredness or mood changes.
People with kidney disease need medical advice before increasing protein.
Eating too many protein-rich foods can add enough calories to stop fat loss.
High protein intake can cause bloating or constipation when it displaces fibre-rich foods.
Very high-protein, low-carbohydrate diets may cause bad breath, thirst, and dehydration.
Dairy-based proteins may trigger digestive discomfort in lactose-sensitive people and worsen acne in some individuals.
People with existing kidney disease should consume high amounts of protein only with medical supervision.
Protein still contains calories, so excessive portions can prevent fat loss despite a high-protein diet.
