What Is The Low Sugar Diet & How Can You Reduce Your Sugar Intake?

In the supermarkets and shops, shelves are stocked full of sugary snacks and drinks.

What Constitutes a Low Sugar Diet?

According to guidelines its recommended your sugar intake should not exceed 5% of your daily calories.1 This means a typical adult should not exceed 30g of sugar in the diet. The type of sugar which is most detrimental are free sugars, which include those added to fizzy drinks, fruit juices, biscuits, cakes and chocolate. 

There is also a specific ‘no sugar diet’ which includes the removal of all sugar including those in otherwise healthy food sources such as fruit and dairy. This is not advised as fruits are a good source of fibre and micronutrients. 

 

What are the Benefits of Reducing your Sugar Intake?

Weight loss

Eating a large number of sugary foods may mean you gain weight.2 Sugar has a low effect on satiety meaning you will not feel full after eating sugary snacks. This means it’s much more likely you will exceed your required daily calorie amount which may lead to weight gain in the long run. 

Switching your food choices for those with a higher protein and fibre content may result in weight loss.
 

Tooth Care

Large amounts of sugar can wreak havoc on your teeth. If you want to stay fit and healthy and avoid a toothless smile, its best to make sure you are not going overboard with your sugar intake. Specifically, free sugars are the ones that do the most damage and put your dentist in a bad mood.4

 

 

How to Follow a Low Sugar Diet

There are a number of things of you can do to reduce your daily sugar intake and many of them may result in improved dietary habits in general. Using the tips below will help to reduce your daily sugar intake and improve the quality of your diet. 

 

Take Notice of Food Labels

In can often be surprising just how much sugar is in your preferred drinks and snacking options and sugar can often be in foods you wouldn’t expect. Being attentive and making sure to read the food labels can be an informative process helping you make the right choices when it comes to meals, snacks and drinks. 

 

Avoid Sugary Drinks

Your favourite fizzy drinks may well be loaded with sugar well worth looking for the ‘diet’ counterparts. Not just the typical soda drink though, drinks often marketed as ‘healthy’ or ‘low fat’ may also contain a fair amount of sugar. 

Things like ‘healthy’ smoothies or fruit juices can also have a substantial amount of sugar and whilst trying to pick a healthy option you could inadvertently adding unnecessary sugar to your diet.

Go easy on condiments

Ketchup and brown sauce contain a substantial amount of sugar. Making sure you don’t go overboard with the ketchup serving size and reducing the number of meals that you add sauce to can help reduce your overall sugar intake. 

 

Plan your meals ahead

Planning your meals in advance has many benefits. As well as allowing you to monitor your calories, planning your meals can be cost effective and kind to your wallet. 

Importantly for sugar intake, planning ahead can also help to avoid the last minute unhealthy processed choice on the shelf. Although they can be convenient when time is limited, these processed foods often have a high sugar content, which is why it’s recommended to cook your own with fresh and wholegrain ingredients. 

Planning ahead also allows you time to check you labels for sugar content and fit in sweet treats here and there. 

 

Don’t shop when hungry or tired

Traipsing the shops after a long day at work when you’re tired and hungry can make the sugary snacks hard to resist. Especially those placed next to the check out. 

Shopping after a healthy meal (containing fibre and protein) can help you fight off the temptation of fighting off the food choices that can have a negative impact in the long run. Once its bought and in your cupboards at home it’s much harder to resist the sugary snacks whilst watching your favourite box set.

If you are currently consuming large amounts of sugar and suddenly stop, you may find that you start getting cravings for foods high in sugar. This means it’s a good idea to wean off the sugar gradually to avoid any unpleasant symptoms such as cravings, low mood, disturbed sleep, light headedness and nausea.
