I'm TOO Skinny

Posted by Sarah on September 11, 2013 at 4:15 PM

“Wow I look skinny. I should really increase my intake of calories”…. Said hardly anyone ever. As a society, we can become so consumed with worrying about how to lose weight that the dangers of being underweight can actually be overlooked. Underweight is defined as a BMI of less than 18.5 kg/m^2. (google BMI calculator to see where you fall).



This is an especially important topic with the fall and winter runny nose months coming up BECAUSE 1. The immune system can be weakened when underweight. There is an increased risk of developing an infection due to the inadequate intake of nutrients including ANTIOXIDANTS.


Many of the issues associated with underweight stem from consuming too little and thus consuming too little vital vitamins and minerals as well as too few MACRONUTRIENTS (protein, carbs, fat). Not consuming enough protein can cause 2. Issues with repairing the tissues in the body. Most things in the body are composed of amino acids, the building blocks of proteins. So gotta eat those, especially the essential amino acids (body cannot produce these amino acids, you must consume them).



Another common affliction of the underweight is 3. Cold extremities. This is often times indicative of iron, vitamin C, and B vitamin deficiency.



On a even more concerning note, underweight people are prone to 4. Osteoporosis! Osteoperosis is characterized by a curvature of the spine, shrinking, and reduced physical mobility. Fractures are also more likely and may lead to permanent disability. How can you prevent this? Make sure that you’re getting adequate vitamin D and Calcium. Word.
