Gut bacteria making you fat?

This blog outlines why a depleted amount of gut bacteria in your gut will lead to increased weight gain. Why your gut is suffering from depleted bacteria and how you can improve it by eating more pro and prebiotics.

Gut bacteria making you fat?

Over the summer I was away in France and Spain and contracting a tummy bug. In fact, the whole family contracted a tummy bug. The ferry home from Europe was a ‘sticky’ affair.  Luckily we had a cabin where we could empty our bowels and stomach contents at will!

Apologies….. messy I know… Yet we all recovered quickly and back to school and work.

Or did we?

I have been bloated and ‘overweight’ ever since. As I clearly explained to one of my Gorgeous Girls, my gut flora is making me fat. She laughed and said ‘yeah I like that one –  it has nothing to do with the patisseries or baguettes’

Okay okay, you caught me I do agree that I did increase my naughty treats and the beach walk to the hot chocolate shop wasn’t really enough to compensate that sugary treat. However I don’t usually gain weight on holiday, my habits are so well embedded and I can get back into the groove when I return and my body keeps me in balance.

Not this time and here is why… the yucky science bit.

What makes your gut poorly?

  1. Sickness.  Diahorrea strips your body of ALL your bacteria. The natural response to an alien microbe in your body is to GET RID and fast.  And as you remove, you also remove all good and bad bacteria. This leaves your body defenceless.
  2. Antibiotics. It is not just being sick or poorly that strips all your natural bacteria also if you take a bout of antibiotics for the flu. In addition, antibiotics are also used in your food chain, intensely farmed animals are given a lot of medication and antibiotics which you in turn consume.  Antibiotics wipe out bad bacteria and also your good bacteria. Organic meat is not kept in the same way.
  3. Stress. It isn’t just what you are eating it is also stress. Stress can affect your gut because it raises your stress hormone Cortisol which can stop your gut from working properly.

Why do you need good bacteria?

Your gorgeous gut accounts for two-thirds of your immune system and produces twenty hormones, if your gut isn’t working properly you will feel bloated, uncomfortable and unwell.

Good bacteria in your gut will improve your digestion, strengthen your immune system and manufacture vitamins that your body needs. Bad bacteria will cause digestive problems, mental issues and skin conditions.

How do you know if you have a bad gut problem?

  1. Digestive issues – like farting, bloating, heartburn, diarrhoea, constipation, IBS
  2. Bad breath
  3. Vitamin and mineral deficiencies are caused if your gut is unable to synthesise or absorb the nutrients in your food, which will leave you feeling tired all the time
  4. Food Intolerances
  5. Mental issues – your gut bacteria contains neurotransmitters which if not working correctly cause brain fog, OCD, depression and anxiety. Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body’s serotonin is made in the digestive tract. In fact, altered levels of serotonin have been linked to diseases such as irritable bowel syndrome, cardiovascular disease, and osteoporosis

The bottom line is not only will have a physical manifestation of too much bad bacteria but it will also affect your mental well-being as well.

Imbalances in your gut can affect your mood

Serotonin is the HAPPY hormone.  It puts you in a good mood, exercise helps you to produce serotonin and this hormone is also responsible for making us feel pleasantly full after a meal.

There is an important amino acid called Tryptophan that is used to make the happy hormone.  If you have too much sugar or fructose in your body Tryptophan latches onto the sugar and is pushed out of the body, therefore, you are unable to make more serotonin.

Hence links to diet drinks with HFCS (high fructose corn sugar) and anything with fructose on the label can make you DEPRESSED, anxious and sad. Eran Segal ran research on artificial sweeteners like this and discovered that they alter the composition of gut bacteria and cause diabetes in mice.

The point is your gut can affect your mood and your behaviour.

Gut bacteria means your body responds very differently to food than your best friend


Why your BFF can eat ice cream and not get fat!

Your gut bacteria means your response to your food is very personal. Bacteria in your gut will affect your physiology.  Segal’s study analysed 1,000 healthy people and tracked their glucose level response after each meal for a week. It is the largest study to date.

The trend that they discovered was two fold

  1. More carbs you have in your meal the higher your glucose response.
  2. The more fats you have in your meal the lower the glucose response

Glucose response is dependant on variants such as level of exercise, age, blood hypertension, DNA and stress as well as your meal composition.

However, some people in the study had a huge SPIKE in glucose with rice and not ice cream.  How do you explain that?

Microbiome in your gut affects how your body digests your food, whilst your BFF can eat ice cream and not put on weight you can’t.  This could be due to the way you digest glucose, what else you have eaten that day, but this research shows it is also down to the health of your gut bacteria.

In the diagram below which is the better diet – left or right?

gut bacteria - Get Gorgeous

The right has more protein, while the left has no protein or fats and is the fast track to diabetes. Personally, I eat very little ice cream – I know from personal experience that even the diet on the right would cause me to gain weight.  So when the research refers to a ‘good diet’ they specifically mean for that person. Perhaps it is someone who is exercising excessively, very tall and has a nervous disposition which means that they are constantly active.

The interesting point from this diagram is that diets don’t work as a bland ‘one diet suits all’.   Your diet needs fundamental basic consistency and then adaptations to suit you.  A considered approach that works with you as an individual. Work with me to get the results you want.

I do not feel the need to hide less healthy food away but nor do I feel as someone commented that they do not want to eat sweet things at least sometimes. This made me realise that I am feeling generally more confident about food choices.

I think the main reason for this is that your programme is not a diet – so there is no need to feel deprived of anything or feel hungry.  This in turn means not only that I don’t feel cravings for things I “can’t have” and also there is not the feeling that “I have messed up today so it doesn’t matter anymore, I will have to start again tomorrow” which could lead to further unhealthy choices for the rest of the day.

Now I know that the occasional biscuit (or ice cream in hot weather) is not a problem as long as it stays occasional and the good habits are kept up most of the time I am feeling much more confident.  Of course logically I knew this already but now really understand it.

This feels like one of those “light-bulb” moments – realising the benefit of that changed mindset.”
