Each day we all burn many calories a day to keep the body running which is the result of numerous processes. All of this is referred to as our metabolism. This can vary considerably based on gender, height and weight, activity levels and age. Much more details about this topic is covered in the Weight Loss 101 chapter. Here we are highlighting how to calculate your likely daily calorie burn as well as what calorie intake is needed to lose weight. There will be some simple and easy calculators below to do this. Additionally, the more direct methods of metabolism testing will be listed.

The calculators are a good tool but they are not perfect. Keep in mind that the resulting number is a credible estimation but an estimation nonetheless. It will give you a good starting point. Keep two things in mind if you feel that you are ingesting the target calorie intake and not losing weight. First, it is very likely that you are missing 25 to 50% of how much you are actually eating. This typically happens due to unconscious aspects (i.e., not doing this deliberately) and due to not having accurate measurement of the amount of food eaten. To help with the former you can set up automatic cues or reminders to track everything and for the latter challenge a digital food scale can be a great tool. The second thing to consider if you seem to be hitting you intake goal but not losing weight is to do one or two week food experiment. This experiment entails ONLY eating foods that are easily quantifiable when it comes to calorie content. This will be you will likely be eating foods that are packaged so that the serving size is stated, the calories are given for the serving, and you can easily know how many servings you ate. The goal of doing this is to get a very accurate account of calorie intake and to likely show that if a certain amount of calories are ACCURATELY recorded then weight loss will happen. The evidence is overwhelming that ingesting a calorie intake that elicits a calorie deficit will always lead to weight loss. There are NO “broken metabolisms” or “starvation modes” that will inhibit weight loss. The number that elicits a deficit will vary based on individual aspects (see previous) which are taken into account in the calculators. To be clear, for many people this means a relatively low number of calories must be ingested to lose weight (BTW, this is one of the reasons losing weight is difficult). However, it is definitely NOT zero and is likely 1,200 to 1,800 calories to consistently lose about one lb of bodyfat per week.

The following is an example “experiment” week. The calorie intake for each day is about 1,200 calories. This amount was chosen due to the fact that this amount is very likely to elicit at least one pound of fat loss in a week for most people. However, based on your specific requirements, adjust the goal intake. We would suggest, for this one or two week trial, to set an intake that should lead to AT LEAST one pound of fat loss per week and 2 pounds may be a better target for the short time frame. The reason is to clearly see that weight loss will happen which should help to improve the hope and self-efficacy that is need to continue working on eating behavior that will allow weight loss to continue to happen.

Here is an example week (some caveats and clarifications; remember to adjust amounts to your needs and to know that you can make many changes to the food choices, your specific food choices can vary from the example so play close attention to the calorie content of your foods, the goal is to have a very accurate quantity and therefore calorie content, also the meal frequency can vary widely as well, as you can see we have the example set with 3 meals, but feel free to move this up or down, all that matters is the goal intake of calories is met, and many of foods are likely to be considered to be on the higher end of the scale of “processed”, yes, but there is no quality evidence that eating such foods will cause any harm nor will they inhibit weight loss, and again, this is just for a short time and not recommended for long term use at high quantities, but 10-20% of the diet coming from highly processed foods is unlikely to cause poor health and for many people have some of these foods and having a more flexible mindset about foods will help in the short-term and more importantly in the long-term and finally we did focus on getting a good amount of protein per meal, which meals 20 or more grams, preferably 30 grams as getting about this much of this macronutrient is likely to help reduce hunger as well as other health benefits)

Assessing your likely calorie burn for the day and your calorie intake to lose weight

To find out your estimated BMR (basal metabolic rate) and TDEE (total daily energy expenditure, which is the number to focus on, click on the following image to go the the calculator

caloriecalculator.net

 

The following are the more DIRECT methods of testing your metabolism. The major challenge with these methods is they are often not easily accessible. The most accurate option is going to get your BMR tested. These methods can tell you very precisely what your BMR is and the double label water method can tell you what your TEE is. The following methods are all referred to as indirect calorimetry.

The follow three types of indirect calorimetry are not easily accessible but can be available at some Hospitals and University research centers. These are all considered very accurate methods for determining metabolic rates.

  • Double labeled water – the gold standard for accuracy of BMR and TEE
  • Douglas Bag
  • Whole room calorimetry

The following are a few portable devices that can accurately test BMR and are likely much more accessible for personal testing.

Recently a new portable device has come to market that can measure you metabolic rate, it’s called the Breeze. There is at least one study comparing it to a Douglas Bag and it was found to have very similar results. Therefore, it is likely to give a person an accurate measurement of BMR.
