Where can I find a dietitian who can measure my metabolism or how many calories I need per day?

Dietitians can use an indirect calorimeter to measure your metabolic rate or the number of calories you need per day. It is a short and inexpensive test.

The Medical Nutrition and Nutrition Entrepreneurs dietetic practice groups of the American Dietetic Association would be able to perform this test. Dietitians often have their own private practice nutrition counseling services in addition to services provided in a clinic or hospital. You can find a dietitian at the American Dietetic Association. Include your zip code or city / state, the type of service you want (individual consultation) and expertise needed.


What does BEE stand for in nutrition?

BEE = basal energy expenditure. It is the amount of calories your body burns laying awake in bed without moving a muscle. Most people's bodies burn more calories just keeping the body running than they burn up in exercise during a typical day.


Recently I've come across a metabolic diet which supposedly is nothing but eating certain foods that burn off our fat naturally by increasing our metabolism. Do you have a list of the foods that do that? Thank you.

There are no foods that burn off fat by increasing our metabolism. This concept has unfortunately been the basis of many fad diets.

Metabolism is the rate at which you burn the calories you eat for energy (fuel) and absorb nutrients to build body tissues. This process can occur with or without oxygen (aerobic or anaerobic). Your metabolism is affected by gender (males being higher than females), growth periods (infants, children and teens) thyroid, menopause, stress (illness, fever, pregnancy, breastfeeding), exercise, proportion of muscle to body fat and age. Other factors like starvation or quick weight loss diets with less than 1000 calories reduce metabolism in an effort to keep a person alive longer. Persons with eating disorders like anorexia (starvation / famine) and bulimia (binge / vomit) also develop abnormal metabolic rates because of the inconsistent availability of food. Metabolism can slow down even with gradual weight loss, but that can be countered with a regular exercise program lasting 30 minutes, five times a week.

Try my Healthy Body Calculator to determine calorie needs for metabolism (BMR) including daily activities and health goals like weight loss.


I'm trying to find research articles that might talk about metabolism and dieting. Specifically does eating a very low-calorie diet slow down metabolism because it thinks it is starving?

Yes eating a very low calorie eating plan (<600 calories per day) will slow your metabolism as your body thinks it is starving.

You can search PubMed, the U.S. National Library of Medicine.



How is metabolism increased?

Your metabolism is determined by gender, age, amount of muscle you have compared to body fat and the amount of exercise you do on a regular basis. Male's rates are higher than females because of testosterone.

Infants and growing children or teenagers have higher metabolic rates than adults because of growth hormone. Research into the use of HGH (human growth hormone) doesn't increase metabolic rate nor is it a fountain of youth. HGH has some negative side effects for fully grown adults and is only prescribed for children that are not growing at a normal rate.

As you age, men are fairly consistent until about age 70 when testosterone levels drop off. Women's rates increase during pregnancy and even higher when breastfeeding, but drop when they go through menopause. Exercise to maintain or increase muscles helps increase metabolic rate up to 15 hours after exercise. So get up off the couch, turn off the TV and do an exercise you like for 30 minutes, 5 times per week.


I was wondering, how can a person increase their metabolism?

And is it better to workout in the morning, afternoon or night?

Exercise and larger muscle mass increases metabolism. With exercise, especially weight training, your weight may not change and may even go up, but you should lose inches overall unless you are into bodybuilding then you will gain inches. In fact, exercise increases metabolism up to 24 hours after exercise. Current research hasn't proven that exercise time of day affects metabolism, so exercise when it fits into your schedule 3 to 5 times per week. Just do it!


I recently started taking a diet product called Omni Trim. Have you heard of it? It's supposed to curb your appetite and speed up your metabolism? Thank you.

Since I don't know which one of the many Omnitrim products you are using, I'll tell you about a few of them. According to the Omnitrim product information Omni4 is a "special micellized formulation which enables fat soluble nutrients to be converted into stable, water soluble submicrosized particles [which] are readily available for absorption by your body." Actually, this "special formulation" is not necessary for your body because your body is able to absorb these nutrients without the added expense of Omnitrim. In fact, your body can absorb and store excess fat soluble nutrients (vitamin A, D, E and K) and does so in your liver for times when you don't eat enough foods containing these nutrients.

Several Omnitrim products also contain amino acids, such as phenylalanine which is also found in aspartame. Americans typically consume enough (even excess) protein in their diets and since proteins are made up of amino acids, including phenylalanine, it's unnecessary to ingest even more of them in a diet supplement.

While the therapeutic effects of herbal remedies is being studied by the National Institute of Health, some Omnitrim products contain ingredients that are not regulated by the Food and Drug Administration. There was a recent effort to establish FDA regulations for food supplements, which unfortunately did not become law in part due to the lobbying by the food supplement industry against such regulation. The danger with these products is they do not necessarily contain pure or the active form of ingredients. They may contain toxic contaminants and there may also be ill effects like elevated high blood pressure with the use of too much ginseng. Also, health claims on food supplements are not regulated like labels on packaged foods, so food supplement manufacturers can say just about anything on their labels.

As with any drug, there is a risk you take by using this diet product, especially since the FDA does not regulate it. By choosing a variety of foods from the Food Guide Pyramid you will get all the vitamins, minerals and other essential nutrients required by your body without having the added expense of a diet supplement.

If weigh-loss is your goal, you need to assess where you are before you start. Have you tried the Healthy Body Calculator? Your report will provide you with a baseline nutrition assessment and some guidelines to follow for making a change in your weight. You can include your health and nutrition goals as well.

FYI, your appetite center is in your brain and regulated there. Have you heard about leptin? It is being researched as a possible appetite suppressant because it makes your body think it is full.

Do you need to exercise more? The quickest way to increase your metabolism is to exercise which will increase your metabolism for up to 15 hours afterwards.

A lifestyle change (food and exercise) will bring about long lasting benefits, whereas using a weight-loss supplement will not teach you how to make lifestyle changes. As soon as you stop taking Omnitrim, there is the probability that you will gain the weight back because you will most likely return to the same eating / exercise habits you had before.


Is there any commercial carrier of human growth hormone inducers that deliver outside the U.S.? Are there any harmful effects?

None that I know of. HGH is available by doctor's prescription only. Injected HGH stimulates growth, increases metabolism and has other far reaching effects. I would recommend its use only under a doctor's supervision.
