Coke Zero and Ketosis

Coke Zero and Ketosis

We’re receiving lots of comments from customers regarding the recent changes to Coke Zero and the impact the recipe change may have on Ketosis. 

With so much conflicting information, we asked our Nutritional Expert, Ashley English, to clarify exactly what this means for Total Solution customers.

But first, What is Ketosis?

Ketosis is a state of metabolism whereby your body uses fat rather than carbohydrates as its main fuel source. Our Total Solution Plan can stimulate ketosis because you’re eating fewer carbs than normal, producing less insulin and enjoying the maximum fat-loss benefits.

  • Cardiovascular disease
  • High cholesterol levels
  • Increased blood pressure.
  • Type 2 diabetes

And, what are Ketones?

What has changed?

Coca-Cola has announced it is to change its Coke Zero recipe and rename it Coca-Cola Zero Sugar in the UK to make it “taste more and look more” like the original Coke.

In light of the impending Sugar Tax in the UK, Coca-Cola wants to encourage people to reduce their sugar intake. The original recipe ‘Coca-Cola’ recipe contains nine teaspoons of sugar in a 330ml can.

The new Coca-Cola Zero Sugar includes sodium citrate, which can refer to any of the three sodium salts of citric acid, an ingredient of the product used as a preservative.

What is Citric Acid?

Citric acid is a weak organic acid found in citrus fruits. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks.

How Does It Affect Ketosis?

The theory that citric acid consumption inhibits ketosis is not clear-cut.

It is thought citric acid may affect ketosis by impacting metabolism within the liver, primarily during the Krebs Cycle (Citric Acid Cycle) which citric acid is an intermediate of.

The Top 7 Recipes to Keep You in Ketosis

Some people have reported that while they have seen citric acid consumption prevent them entering ketosis and increase appetite, they have not seen it impact ketosis once it has been established.

What Does This Mean For Me?

Everybody is different, in size, shape and sensitivity to certain foods.

Even if avoiding citric acid, establishing and maintaining ketosis varies from person to person and it is important for the individual to determine their threshold and establish whether citric acid has any effect on ketosis, appetite or fat loss on a ketogenic diet.

Is There Anything I Can Use Instead?

While water is always the best way to stay hydrated, we know that occasionally you might need a sweet fix. Many Total Solution customers also use Dr.Pepper Zero as a sweet fix to help them on their way. Other brands such as Tesco and Asda’s own brand Diet Coke and Sainsburys Sparkling Water, along with green tea are also suitable (but always check the label).
