Fat Ratios and BMI, by Becky Delgado, MPH, RD, LD/N
BMI- BODY MASS INDEX- Height to weight ratio (this number will change in direct correlation to weight); once a person moves from a BMI over 35-40+, to under 35, the risk of medical conditions related to obesity significantly decreases.
FAT%- Body fat %; this tells what percentage of your body composition is comprised of body fat.
We do need some fat for body heat, energy, and protecting internal organs, so you can not eliminate this number all together. Women generally need at least 12 (on the VERY low end)-20% just to live, function, have children, etc., whereas men only need about 3-4%, so again, women you must expect to need more body fat than your husband, co-worker, or another male participant in your group. Men do not need body fat to reproduce, and therefore will tend to lose it more quickly than women.
Things to Remember:
*A healthy weight loss is 1/2 lb. to 2 lbs. a week; normally your body can not physiologically lose more than this a week with healthy nutrition and exercise. Do not get frustrated with this loss! Over time, a consistent pound lost a week will add up to 10 lbs, 15 lbs, 20 lbs….and unlike other programs or diets, this weight WILL stay off!
*If your weight is not dropping, or is staying about the same, but you are decreasing body fat % and fat mass, this is GREAT! You will notice your clothes fitting looser. You should not focus too much on the weight number– when you add exercise and/or strength-training into your life, initially it will seem like you are not losing. Be patient with yourself. You are slowly burning more calories at rest and increasing your metabolism and in the long-term, this will help you lose more weight and more importantly, keep it off.
It is very important for tracking purposes that you weigh in each week, but do not get hung-up on the numbers. If you are eating healthy (small meals throughout the day, increasing fiber, decreasing fried and fast food, staying hydrated) and increasing physical activity, your body will respond- and thank you for it!
This week we discussed dining out healthfully. Do not forget the importance of portion sizes. Whenever possible split the entrée with a buddy or take home half the meal. If we eat the large portions served today we will gain weight. Order water instead of sweet drinks and enjoy the company and the atmosphere of the meal. Being mindful and taking your time to eat at a slower pace will help you fill up with less food and less calories.
Keep up the great work you are doing! We are all very proud of your commitment to be fit…
Your dietitian for life,
