Researchers at the University of Texas’s Health Science Centre found that people who drank diet soft drinks every day put on more than three inches around their waistlines in a decade. The study, published in the Journal of the American Geriatrics Society, focused on 749 adults aged 65 years or older over a 10-year period.
- Those who drank diet fizzy drinks saw their waistlines expand nearly three times as much as non-drinkers, by an average of 2.11cm.
- Non-diet drinkers’ waists only expanded 0.77 cm
- Those who occasionally drank diet beverages experienced a 1.83 cm growth
A 2014 study published in the journal Nature suggested that diet fizzy drinks could cause weight gain due to artificial sweeteners altering the body’s natural gut bacteria. The study, published in The Journal of Physiology, suggests it is hard to fool the brain by providing it with “energyless” sweet flavours. Our pleasure from consuming sweet solutions is driven by the amount of energy it provides. Artificial sweeteners trigger insulin, which sends your body into fat storage mode and leads to weight gain
- There is some evidence to show that large quantities of carbonated drinks (more than three litres each day) can cause bone thinning and tooth decay. They can also trigger the ‘jitters’ in a small group of people who are caffeine sensitive.
- Carbonated drinks don’t bring any vitamins or minerals to the diet.
- People who drink too many fizzy drinks could be missing out on essential nutrients,’ says Catherine Collins of the British Dietetic Association.
- People who rely on pop tend to leave out other drinks which can contain valuble nutrients including calcium from milk and vitamins from fruit juices.
If you are trying to lose weight, avoid the expensive diet drinks and stick to water or other healthy options.
