It may be easy to tell if your diet needs improvement without looking at your plate.
Registered Dietitian Kristin Kirkpatrick says your body may give off subtle signs that you're not eating healthy.
She says your skin and hair can give "tell-tale" signs that you may need to re-think what you're eating.
Kirkpatrick says, "Bad hair days" and premature skin aging may mean you need to add something a little more nutritious to your diet.
Kirkpatrick adds, "Individuals that are either on starvation-type diets or diets that restrict protein significantly often have very dry hair. So, if your hair is dry the first thing I would look at is how much protein are you getting in the diet and how can you get more."
Kirkpatrick says if you feel tired all of the time, you may need more lean protein and vitamin c in your diet.
The protein can help stabilize blood sugars, while the vitamin c may lower oxidative stress. But if you're not feeling well it's also a good idea to see your doctor.
