Zero and Diet Drinks

  • Zero and diet drinks contain artificial sweeteners instead of sugar
  • No direct blood sugar rise, but metabolic effects nonetheless
  • 38% higher diabetes risk with daily use (research 2024)
  • Sweeteners strengthen cravings for sweets and disturb microbiome
  • Water, tea, and coffee are the healthy choice

Zero and diet drinks are soft drinks or other products in which sugar has been replaced by artificial or natural sweeteners:

SweetenerType
AspartameArtificial
SucraloseArtificial
Acesulfame-KArtificial
SteviaNatural

They contain hardly any calories and usually have no direct influence on blood sugar levels.


The reasoning is logical:

  • No sugar
  • So no calories
  • So no weight gain

But the body responds differently than expected.

Artificial sweeteners do provide a sweet taste, but no energy. This can:

  • Stimulate the reward system in the brain
  • Actually strengthen the need for sweets
EffectDescription
More cravings for sweetsOr carbohydrate-rich products
Less satietyAfter meals
Persistent preferenceFor sweet flavors

What does research say about diabetes risk?

Section titled “What does research say about diabetes risk?”

A large Australian population study (Monash University, 2024) showed:

People who drink one ‘zero drink’ daily have a 38% higher risk of developing type 2 diabetes compared to non-users.


SystemPossible effects
GutChange in composition and function of microbiome
BrainStrengthened stimulus of reward system, more cravings for sweets
PancreasPossible slight insulin response to taste stimulus
Liver & fat metabolismInsufficient metabolic rest, higher chance of insulin resistance
Dental healthLess cavities than sugary drinks, but possible effect from acid

Sweeteners like stevia or erythritol are often considered ‘natural,’ but they also maintain the taste preference for sweets.

AssessmentExplanation
With moderate useAppear less harmful than synthetic sweeteners
Long-term effectsStill insufficiently known

The starting point remains: less sweet = metabolically calmer = healthier.


No.Advice
1Water remains the best choice — still or sparkling with lemon, lime, mint, or cucumber
2Limit zero and diet drinks to occasionally
3Don’t use sweeteners in coffee or tea
4Check labels — sweeteners are also in yogurt, chewing gum, and sports drinks
5With insulin resistance or diabetes: use zero drinks only occasionally

DrinkBenefit
WaterOptionally with lemon or sparkling
Herbal tea, rooibosCaffeine-free, no sweeteners
Green or black teaAntioxidants
Coffee without sugarOr milk alternatives
Homemade infused waterWith herbs, citrus peel, berries, or ginger

Veelgestelde vragen

Are zero and diet drinks healthy?

No, despite no calories, regular use appears to contribute to metabolic disruption and increased diabetes risk. They are a less bad intermediate step, not a healthy replacement for soft drinks.

Do zero drinks increase diabetes risk?

Yes, Australian research (2024) showed that one zero drink daily increases the risk of type 2 diabetes by 38%. Artificial sweeteners can contribute to insulin resistance and disturbed glucose regulation.

How do sweeteners affect the body?

Sweeteners provide sweet taste without energy, which stimulates the reward system and strengthens cravings for sweets. They can change the microbiome, cause a slight insulin response, and disturb metabolic rest.

What are healthy alternatives?

Water (optionally with lemon or sparkling), herbal tea, rooibos, green or black tea, coffee without sugar, and homemade infused water with herbs, citrus peel, or ginger.
