Headaches: Headaches are a common side effect when cutting back on carbs, particularly during the initial stages of carbohydrate withdrawal.
Irritability and Mood Changes: Some individuals may experience irritability, mood swings, or changes in mood when eliminating carbs due to changes in blood sugar levels and neurotransmitter balance.
Digestive Issues: Decreasing carbohydrate intake may result in digestive changes, including constipation, diarrhea, or changes in bowel movements.
Bad Breath: A side effect known as "ketosis breath" can occur when the body burns fat for fuel, releasing ketones, which can lead to a distinctive odor on the breath.
Nutrient Deficiencies: Eliminating certain carbohydrate-rich foods can result in reduced intake of essential nutrients like fiber, vitamins, and minerals.
