How to have a healthy metabolism, by Dr Simoné Laubscher

Want to have a healthy metabolism? Dr Simoné's latest blog explains how to determine your basal metabolic rate (BMR), gives you her 10 top tips to boost your metabolism & unpacks the science behind metabolic function so you can live lean with minimal pain!

Metabolism, what a mine field of a topic! So many myths and opinions out there it can leave you feeling very confused and overwhelmed. My goal is to give you some good, clean scientific facts that you can incorporate into your daily life, helping to transition you into optimum health.

So what is metabolism? According to Dr Mandal, MD Metabolism is ‘a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism. Metabolism can be conveniently divided into two categories: Catabolism - the breakdown of molecules to obtain energy and Anabolism - the synthesis of all compounds needed by the cells.’ We as humans are made up of around 100 trillion cells which means that your cells are going through metabolic chemical reactions on a daily basis, allowing us to survive. Energy is a vital part of metabolism and why nutrition is also vital for metabolism. The essential metabolic pathways require the correct nutrients to function correctly. Essential nutrients supply energy (calories) and supply the necessary chemicals which the body itself cannot create and must get from our diet. What we eat provides a variety of nutrients that are essential for the building and repair of body tissues, and for the efficient functioning of the body.

The body needs essential nutrients like carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and around 20 other inorganic elements, which it can only get from the food we eat. The major elements are supplied in carbohydrates, fats, and protein. In addition, vitamins, minerals and water are also essential for all metabolic functions to run smoothly.

During this complex biochemical process, calories in food and drinks are combined with oxygen to release the energy your body needs to function on a daily basis. The number of calories your body needs to carry out these daily functions is called your basal metabolic rate. This is what most people are referring to when they speak of having a slow or fast metabolic rate. There are three main factors which influence your basal metabolic rate. These include;

  1. Your sex- men usually have a higher muscle to fat ratio, so therefore a higher level of living tissue (muscle) over dead tissue (fat) and therefore a faster metabolism.
  2. Your age- the older we get more muscle is usually lost therefore slowing down your metabolism
  3. Your size and body composition - the bigger you are the more calories you tend to burn at rest

Your basal metabolic rate that allows your body to have enough energy for its daily functions accounts for about 70% of your daily calories burnt. Two other factors influence your basal metabolic rate- Thermogenesis and physical activity. Thermogenesis involves processing digesting, absorbing and transporting food to create heat. This is why eating spicy and chilli/hot foods can help with your thermogenisis and production of heart thus having a positive effect on your metabolism. Physical activity and exercise in interval bursts such as running/walking intervals, playing tennis, walkcycling, climbing stairs etc as a specific exercise session or as incidental exercise whilst going about your day, all add up to total calories your body burns each day. Physical activity is by far the most variable of the factors for we all respond to exercise differently and weight baring exercise such as running will always burn more calories than weight supportive exercise such as cycling. This is due to the extra calories needed to carry your own body plus the calories burnt from the exercise.

So how do you calculate your average basal metabolic rate (BMR)? A reliable formula is the Mifflin St Jeer Equation.

For men; BMR= 10 x weight in kg + 6.25 x height in cm - 5x age in years + 5

For women; BMR= 10 x weight in kg + 6.25 x height in cm - 5x age in years - 161

This will give you a great foundation to work from.

There are many factors that influence our metabolic rates and often more than one factor is involved. A combination of genetics, hormones, diet, activity level and the impact of environment on your lifestyle, including sleep, physical activity and stress. Of corse to lose body fat one must create an energy deficit so you eat less calories that you burn but this can get all very stressful and obsessive. I am always one more interested in counting nutrients over calories, but it is important to understand the science of calories in v’s calories out is an important factor when determining metabolism and your fat loss formula. When I determine a patients unique fat loss formula I take into consideration the fuel v’s the function debate. For years I have treated patients who came to me miserable having cut out all fun foods in their diet and still not having reached their goals. This is because they reduced their calories down to such a level they went into a degree of starvation which in turn slowed their metabolisms down. My ethos is to get your metabolism functioning well, support digestion and absorption and in fact all the 11 systems of the body, for if you are functioning well you can have more fun with your diet and literally have your cake and eat it too. If you keep on eliminating food groups from your diet you will end up with only fish and lettuce on your plate, feeling miserable and probably not reaching your health goals anyway. I love fish and lettuce but I love eating many other foods too.

The best option is to support function and then add in good clean lifestyle eating habits so you get fast results and you minimise suffering! At our Rejuv Clinics we are anti-suffering and most patients come back a few weeks after the first session and comment how easy their plan was and how most of their symptoms have gone, that is music to our ears. The key is to eat the right foods for you and to get your body absorbing your food and for your metabolism to convert the calories you eat into a good level of usable every.

A healthy metabolism also depends on an alkaline environment for over acidity corrodes body tissue and slows metabolism. What you eat needs to balance your body chemistry and bring harmony, not wreak havoc. Similarly this is how the universe operates by keeping opposites in balance and the body’s internal universe is the same. The more acidic you are the more you will crave junk foods and feel more tired and sluggish all the time. The term pH actually refers to the concentration of hydrogen ions and this moves the pH to being acidic (less than 7) an alkaline (higher than 7). In blood it takes around 10-15 times as much base to neutralise a given amount of acid. It is for this reason that adopting a lifestyle that is prone to keeping you more alkaline than it is to always keep repeating of being acidic and then having to re-gain your alkaline balance.It is best that our blood maintains a pH level of 7.365 which is a milk alkaline level. This is to be your average level throughout the day, for your levels will fluctuate from acidic to alkaline but we generally want you to live more alkaline than acidic. Our urine should fluctuate between slightly acidic to alkaline for fist thing in the morning your urine will be slightly acidic which it is best to test yourself mid-morning and or before for morning caffeine hit! All of our bodies 11 systems work with a delicate balance between acid/alkaline balance. In the early stages of imbalance symptoms are mild such as skin eruptions, headaches, sinus, allergies and a weak immune system. Once you live for an extended period before too acidic your organs become weakened and you can see dysfunction in your thyroid, liver, adrenals etc. when you are too acidic your oxygen levels decrease and cellular metabolism slows, disease occurs and cells death rates increase. This is why getting your metabolism & your cellular metabolism at optimum not only for your waist line but for your overall healthy and longevity too.

The body will do anything to stop getting too acidic and will tend to store toxins and acid wastes in our body fat, thus inviting body fat to hang around. There are certain minerals which have a good neutralising capacity and help to detoxify string acids. These minerals include potassium, calcium, magnesium and sodium. A healthy body will have a good reserve of these minerals to protect the body from exposure to too much acid. if these levels are too low fro a prolonged acidic lifestyle then calcium will be leached out from our bones and magnesium from our muscles. The lymphatic system will then try to get rid of the acid and once tis fails the acids are dumped back into the blood and so the vicious cycle starts all over again. The body will dump acids in any area possible to try to protect itself- in the liver, pancreas, breasts, brain, colon or any fatty tissue in the breasts, hips thighs and belly. This continuous process of acid waste breakdown and acidic / toxic storage is the raging process itself. The good news that is is not based on age and you are helpless to this system. You can choose a more alkaline over acidic lifestyle so your body has a good reserve of acid buffering minerals and your organs are functioning correctly so the body is able to process some more fun foods on weekends for example. I live and suggest to my patents to live 80:20 so that 20% of the week (1.5 days) you have fun, you at your favourite foods and drinks but you balance this out by eating clean in the week. If your body fat is too high have 1 free meal per week instead the 1.5 days till you get back into balance and then move into the maintenance level of 1.5 days off per week. I’m not one for counting calories but if you make up half of your plate with salads & veg & once quarter of protein (the organic/ non-hormones/ line caught varieties) and 1/4 carbohydrates such as spelt, rye, rice, quinoa, sweet potato etc and then add a tablespoon of a food fat such as love or flax oil or avocado or nuts to that meal you will be in a great place to stay more alkaline, focussing on nutrient rich foods, which will support the function of all of your 11 systems including your metabolism.

Yeast over growth / candida can also effect your metabolism, your appetite and general food cravings. I go into more detail about candida in my digestion article part of this Wellness Series but for now let me give you a few facts will further help your metabolism. Candida is the latin name for yeast in the human body but is more of a fungus, being a single celled forms that inhabit land, air and water. Candida is part of your digestive and immune systems and it is essential to life as part of your good and bad bacteria levels. it is the overgrowth of the candida which is the problem. In addition to the damp, acid wastes and mucus candida creates since it thrives on sugar guess what you end up craving? Sugar and carbs of course for both turn into glucose once they are eaten. So you don’t have to deal with your own levels of food cravings but the cravings of the candida for glucose so it can survive! This obviously has disastrous effects on your metabolism and body fat and cellulite. If this wasn’t enough the candida itself also produces mycotoxins (fungus) and exotoxins (bacteria) which ferment in your food, particularly glucose generating foods, go into our blood stream and poison our whole system. for millions of years these yeasts and fungus have been on the earth and they have developed into millions of different forms, but have experienced little genetic change. They can survive for thousands of years dormant and have now been found living in tombs recently excavated in Egypt!! it is not the yeast and fungus itself which is the problem it is the toxic waste they produce which make us sick and make us hold onto necessary weight.

Top 10 tips to have a healthy metabolism

  1. Alkalise- by keeping your acid wastes in check all of the 11 systems of your body will be functioning correctly having a wonderful positive effect on your metabolism. Eat more plants & less animals & to fast track your life add in a super greens powder that not only alkalises but also supports all the 11 systems of your body including; the digestive, nervous, endocrine, skeletal, muscular, cardiac, respiratory, circulatory, immune, integumentary (hair, skin & nails) & excretory systems. Such a super greens powder is The Super Elixir & you only need 2 teaspoons per day.
  2. Thermogenic- try to warm your system up & therefore boost your metabolism by eating more chilli, cayenne pepper, garlic, ginger & green tea.
  3. Interval training- it is not enough just to go for a walk if you really want to give your metabolism a good kick. Instead try doing intervals from medium to very hard such as walk for 4 minutes & sprint for 1 minute & sustain this for 40-45 minutes.
  4. Kill the candida by cutting our sugar- as per the above information you need to clear out the candida & fungus which will allow your metabolism to function at optimum.
  5. Eat clean, up your fish protein & good fats such as avocado & keep your treats to weekends. This will keep your metabolism in check but also allow you to psychologically stay string during the week knowing that you will be rewarded on the weekend. Since we win the game in the mind the best is balance over abstinence.
  6. Determine your BMR with the Mifflin St Jeer formula provided above so you know where to start from.
  7. Start your day with a kick by having a pint of water plus the juice of 1/2 a lemon, half teaspoon of grated ginger & 1-2 pinches pf cayenne pepper
  8. Hydrate- your are made up of around 100 trillion cells & if you drink 2-3L filtered water per day your cells will be like big fat healthy grapes instead of shrivelled up raisins, allowing goodness to flow in & junk to be removed. This takes the pressure off all the systems of the body, thus boosting your metabolism
  9. Help your gut- sounds obvious but chew your food around 20 times per mouthful to support digestion & reduce stagnation. This will also help you feel full for it takes about 20minutes for your gut to speak to your brain to say you are full and many over eat not giving their brain time to read how full you are. Limit liquids to maximum 200ml per meal to not dilute your stomach acids.
  10. Boost your metabolism with herbs- if you know you have a sluggish metabolism & for the amount you eat and exercise your body fat levels are too high you may need some metabolic support. At Rejuv I have formulated a whole range of products with 6 products out of my range for metabolic support to accelerate fat loss, support digestion and to reduce appetite.
