Question
my friend wants to lose weight.she is following a diet that contains 20%carbohydrates,40%fat,and 40%protein.why is this diet designed to limit fat deposition?

Answer
Carla,

I (or any reputable dietician) would never recommend a diet containing 20% carbohydrates, 40% fat, and 40% protein.  Also, there is no reason such a diet should "limit fat deposition".  That is a completely baseless claim.

Weight loss is dependent on burning more calories than you eat.  It makes no difference what the proportions of carbohydrates, fats and proteins.  Certainly eating foods with whole grains and fiber (complex carbohydrates) will fill you up more than foods with little fiber and added sugar (simple carbohydrates).  Also, low-fat meats and diary foods have equal protein, but less calories than high-fat meats and dairy products.  But, calories are calories.  And calories are what count!

It is recommended that we eat approximately 50-60% carbohydrates (mainly complex carbohydrates), 25%-30% fat (mainly unsaturated fats and limiting saturated fats from animals) and 15% protein.  Limit total calories (or portions sizes) to maintain a healthy diet.  Also, get regular exercise.  Learn more about a healthy diet, including complex carbs and unsaturated fats, at:

Tell your friend to drop such a crazy diet plan.
