According to a team of researchers, our inability to ditch sugary snacks and drinks may have a lot to do with our sleep patterns.
The researchers found that when we are sleep deprived we are more likely to crave sweet food than when we're fully rested.
Unfortunately, they also found that high consumption of sweet food was linked to poor quality sleep, meaning it's easy for us to get trapped in a negative cycle.
The research was lead by Dr Anna Weighall of the University of Leeds in partnership with bed company Silentnight.
Dr Weighall's research team analysed results from previous studies to compile one in-depth report on how sleep and sugar are linked.
Citing a previous study in the Journal of Sleep Disorders: Treatment & Care, the researchers said that people who sampled a high sugar diet found it had a negative impact on their sleep.
In fact, young people (those most likely to have a high calorie, high sugar diet) were most likely to report short durations of sleep.
The researchers found the production of leptin - a hormone that reduces hunger and peaks during sleep - is decreased when sleep is decreased.
While leptin decreases hunger, a hormone called ghrelin increases hunger.
A reduction in sleep was also found to increase ghrelin release through the body, causing us to crave sweet, salty and typically calorific foods.
Unfortunately that's just one side of the sleep/sugar cycle.
The scientists also found hormonal changes that occur due to weight gain were likely to make individuals feel more hungry than they would otherwise. In turn, the greater calorie intake would cause them to experience inadequate sleep.
Commenting on the findings Dr Weighall said: "With talk of a ‘sugar tax’ we are all increasingly aware of the negative effects of sugar on the nation’s health, especially in relation to weight gain and obesity.
"However, scientists have also shown that our diet can be important for sleep too. There is evidence that both adults and children who eat high calorie diets are more likely to sleep less."
Dr Nerina Ramlakham, Silentnight's resident sleep expert, said she believed sensitive sleepers should try to avoid sugar.
She said: "What is interesting from the research is that we see how quite quickly the relationship between sugar and sleep can become a negative cycle - with what we put into the body disrupting our sleep patterns, we are then kept awake and our body begins to crave all the things which keep us awake.
"Sugar can cause more restlessness and hyperactivity, especially if you’re a sensitive sleeper so best to minimise it.
"I would encourage people to break the cycle with a low sugar, or better still sugar free, drink before bed. If you have a hot drink before you go to sleep, it's best to make it with almond milk, which is high in tryptophan, which is proven to improve sleep."
For a mid-day snack, try two pieces of celery ribs with natural almond butter. SUGAR COUNT (in teaspoons): 1
When you're shopping for Greek yogurt, make sure you're reading the labels carefully. You want to look for yogurt that has no added sugar or is under the 1.7 tablespoon amount. You can also add fresh fruit, like berries, to your yogurt for a sweet kick. SUGAR COUNT (in teaspoons): 1.7
One slide of roast beet, one tablespoon of cream cheese and two asparagus spears. SUGAR COUNT (in teaspoons): 0.6
Buy your own shelled edamame and steam about half a cup for an afternoon snack. Watch the salt! SUGAR COUNT (in teaspoons): 0.8
For this snack, author and certified nutrition consultant Dr. Brenda Watson uses two ounces of cheese. Make sure your cheese and deli meats are bought fresh, and not packaged. SUGAR COUNT (in teaspoons): 0.4
Another snack idea is a handful of mixed nuts without any added seasoning, sugar or salt. SUGAR COUNT (in teaspoons): 0.4
Six slices of cucumber, three squares of cheddar cheese and one slice of turkey breast cut into thirds. SUGAR COUNT (in teaspoons): 0.1
Skip the beef and choose turkey instead. If you can't find packaged turkey jerky, you can always make your own at home. Watson recommends three pieces for a snack. SUGAR COUNT (in teaspoons): 0.4
For a nighttime snack, try a 1/2 cup of baby carrots and a 1/2 cup of hummus. SUGAR COUNT (in teaspoons): 1.2
Two ounces of shredded smoked salmon, one teaspoon of mayo, black pepper and two celery ribs. SUGAR COUNT (in teaspoons): 0
Mixing both your servings of dairy and fruits, this recipe calls for 113 grams of cottage cheese (4 ounces) and 1/4 cup of pineapple. SUGAR COUNT (in teaspoons): 1.8
Watson uses cacao in her mousse recipe, but we also like this avocado and chocolate one from I Quit Sugar. SUGAR COUNT (in teaspoons): 0.6
Instead of putting turkey and cheese in between two slices of bread, Watson suggests taking one slide of deli meat, one slice of cheese and wrapping it in a lettuce leaf for a snack. SUGAR COUNT (in teaspoons): 0
