Want to lose weight? Eat SLOWLY! People who scoff their food too quickly are more likely to be overweight, study finds
- Researchers tracked the height, weight and BMI of 800 UK adults and children
- They also asked people to report their eating habits and how quickly they eat
- The team found a strong link between obesity and people eating food quickly
- This link between speed and weight was present in both adults and children
The best way to lose weight is to eat your food slowly, the authors of a new study claim, after finding people who eat quickly are more likely to be overweight.
Researchers from the University of Roehampton and Bristol University worked with 800 volunteers who completed surveys about their weight and eating rates.
The study included adults and children, with authors discovering no different between the two when it comes to the impact of fast eating on obesity.
They found that both adults and children develop larger waistlines and a higher body mass index (BMI) if they are quick eaters.
The team behind the study say this clears up a long-held misconceptions that adults aren’t as susceptible as children to becoming obese by eating at a fast pace.

HOW TO CALCULATE YOUR BODY MASS INDEX – AND WHAT IT MEANS
Body mass index (BMI) is a measure of body fat based on your weight in relation to your height.
- BMI = (weight in pounds / (height in inches x height in inches)) x 703
- BMI = (weight in kilograms / (height in meters x height in meters))
- Under 18.5: Underweight
- 18.5 – 24.9: Healthy
- 25 – 29.9: Overweight
- 30 or greater: Obese
Over 800 adults and children in London took part in the research, which was based on a survey completed by participants providing their own self-reported eating rate with response options ranging in a scale from very slow to very fast.
Researchers recorded participants’ height, weight, waist circumference and BMIs, measured under their supervision.
Faster eating rate was significantly associated with a higher BMI and larger waist circumference in both children and adults.
The UK has one of the highest rates of childhood obesity in Europe, with around 1 in 10 children aged 4-5 classed as obese, increasing to 1 in 5 for children aged 10-11.
Adults don’t fare much better, with 2021 NHS data showing 67% of men and 60% of women are considered overweight or obese in the UK.
These findings add to growing evidence of studies showing a clear relationship between body mass and eating rate, particularly amongst children.
The idea being that children who are quick eaters consume larger amounts of food at mealtimes, which in turn contributes to an increase in BMI.
Dr Leigh Gibson, lead researcher on the study said the research was particularly significant as it shows eating quickly affects adults and children the same way.
“Previous studies that looked into the association between consuming foods at a fast pace and increased energy intake focused solely on children.
‘However, by assessing both adults and children, we were able to debunk the notion that adults are immune from the effect of eating quickly on obesity that have been established in children,’ Gibson added.
The team also found a difference in birth order of siblings, when it came to determining just how quickly they were likely to eat their food.
They found that first‐born children were twice as likely to eat faster compared to children who were not first‐born.

Adults with no siblings reported eating slower than adults who were not first‐born and a higher number of siblings was associated with faster eating rate in children from Bristol, but not in children from London.
London adults without siblings ate slower than those with two or more siblings, but having one sibling was associated with eating faster than having two or more.
‘Guidance for preventing obesity in both children and adults needs to be revised to take into consideration not only the types, quality and quantity of foods consumed, but also the eating rate,’ explained Gibson.
‘By slowing down and taking longer to eat our meals, we can keep our waistlines and BMIs in check.”
The findings from this study have been published in the journal Clinical Obesity.
OBESITY: ADULTS WITH A BMI OVER 30 ARE SEEN AS OBESE
Obesity is defined as an adult having a BMI of 30 or over.
A healthy person’s BMI – calculated by dividing weight in kg by height in metres, and the answer by the height again – is between 18.5 and 24.9.
Among children, obesity is defined as being in the 95th percentile.
Percentiles compare youngsters to others their same age.
For example, if a three-month-old is in the 40th percentile for weight, that means that 40 per cent of three-month-olds weigh the same or less than that baby.
Around 58 per cent of women and 68 per cent of men in the UK are overweight or obese.
The condition costs the NHS around £6.1billion, out of its approximate £124.7 billion budget, every year.
This is due to obesity increasing a person’s risk of a number of life-threatening conditions.
Such conditions include type 2 diabetes, which can cause kidney disease, blindness and even limb amputations.
Research suggests that at least one in six hospital beds in the UK are taken up by a diabetes patient.
Obesity also raises the risk of heart disease, which kills 315,000 people every year in the UK – making it the number one cause of death.
Carrying dangerous amounts of weight has also been linked to 12 different cancers.
This includes breast, which affects one in eight women at some point in their lives.
Among children, research suggests that 70 per cent of obese youngsters have high blood pressure or raised cholesterol, which puts them at risk of heart disease.
Obese children are also significantly more likely to become obese adults.
And if children are overweight, their obesity in adulthood is often more severe.
As many as one in five children start school in the UK being overweight or obese, which rises to one in three by the time they turn 10.
