9.It Can Tax Your Heart
Very low-carb diets also are high-fat. Your saturated fat intake should be no more than 5% to 6% of your total. Focus on healthy fats like those in avocados, olives, and nuts. On the keto diet (as well as less strict low-carb diets like Atkins and Paleo), your triglycerides and HDL (“good”) cholesterol levels will likely get better. But you may see a rise in LDL, or “bad” cholesterol, which can also lead to heart disease.
10.You Might Feel Moody
Your state of mind can get wonky when you sharply cut healthy carbs that send sugar to the brain. You might feel grouchy. One study found people who followed low-carb diets over time had less serotonin in their brains than those who were on low-fat diets. Healthy serotonin levels help guard against anxiety and depression.
