Lemon, PhD E-mail: plemon@julian.uwo.ca There has been debate among athletes and nutritionists regarding dietary protein needs for centuries. Although contrary to traditional belief, recent scientific information collected on physicallyenCommunityServer 2008.5 SP1 (Build: 31106.3070)http://articles.mercola.com/sites/articles/archive/2002/08/21/protein.aspx#37907Tue, 27 May 2008 20:21:28 GMT24451277-a5aa-4add-96dc-64081bfd86fa:37907Talitha cumi<p>From &quot;DR. Mercola's Total health program&quot;, I learned that I am a 'mixed type' person. So I have to eat 30% Protein / 20% Fat / 50% Carbohydrate. I supposed that it meant these percentages in energy intake, so in kcal. Doing some math, given that I need 1800 kcal a day (inactive person), means that I have to eat 540kcal Proteins/ 360kcal Fat/ 900kcal Carbohydrate. More math ( and a booklet about kca and nutrition values) learned me that 1g protein = 4kcal , 1g fat = 9kcal ,1g carboh. = 4kcal So I have to eat 135g Protein/ 40g Fat/ 225g Carbohydrate. On your website I found that I (non-exercising typical woman) need 60g protein a day. But when 60g Protein (=240kcal) = 30% of my daily kcal intake, than I need 18g Fat (=160kcal =20%) and 100g Carbohydrate (=400 kcal =50%). So then I would be eating only 800kcal a day. Where am I going wrong? </p> <img src="http://articles.mercola.com/aggbug.aspx?PostID=37907" width="1" height="1">
