Metabolism is a most common word now in the health and fitness field and most people still don't understand the basics. They just throw around the word loosely. People are getting caught up on BMR (Basal Metabolic Rate); RMR (Resting Metabolic Rate), Metabolic Set point, etc. I will be dealing with these on a more detailed article later.
Metabolism is simply the amount of calories burnt for the body to function efficiently. That is the simplest definition though there are many things to still understand about how it functions. However it should be understood clearly that metabolism can be affected by conditions like environment, exercise, diet, etc.
My purpose in writing this post is that many have been saying they want to lose weight, or change body composition or the dreaded 'what diet should I be on?' question.
The first step is to assess your metabolism which is done by checking your body temperature. You can do this with a thermometer. The best time to do this is late afternoon or early evening since you have already started running through the day. Do this 4 days in a row. Check your readings with the table below
If it is 37C (98.6F) you are at optimal and fine.
If it is 36C (97F) your metabolism has been reduced by 10%-20%
If it is 35.5C or below (<97F) your metabolism rate is in pretty rough shape.
If you find your self anywhere below 36C (97F) dont even think of starting a diet. Get back your optimal body temperature first. This requires eating more and supplementation for the first few weeks before you can even launch into a fat loss or body recomposition diet. Ideally, you might want to continue eating about 300- 500 calories more everyday for about 3-4 weeks. You might need a few more weeks but after three weeks measure your body temperature again and see if its pack to optimal and sustaining.
The reason to eat more is simple. You need more energy in the body to raise your metabolism to normal. Supplementation is necessary to cover nutritional deficiencies and in getting hormones to start working correctly again.
Before you get into any kind of weight loss diet , assess yourself first using the method given above and then start to focus on fat loss or diet.
