Are you in denial about your weight and eating?

Studies show that many people are unaware of their weight status, same goes for about how much they actually eat

Denial is a powerful coping mechanism. When it comes to eating and weight issues many of us seem to be living in ignorant bliss. 

In much the same way many of us believe ourselves to be above average drivers, studies show that weight misperception is widespread. People don’t recognize overweight in themselves or in their loved ones, and even health professionals fail to identify overweight and obesity when just observing a patient. 

About 48 percent of overweight men and 23 percent overweight women considered themselves about the right weight in a study including about 16,000 people, and even among obese people only about 10 percent were aware of the extent of the extra weight they carried. About 8% of obese adults considered themselves to be "about the right weight” in another study.

We often don’t see the expanding weight on ourselves, and we don’t see it in our own kids: A meta analysis of more than 64,000 kids shows that 50 percent of parents did not identify that their kids were overweight or obese, and seriously underestimated their kids' weight status.

It may be that our eyes have acclimated to heavier bodies because so many of us are now overweight. Looking at mid 20th century footage of the movie-star-thin general public from that era surprises us, and contrasts clearly with our two-thirds-overweight/obese population. 

We’re unaware of how much we eat

We not only see ourselves as smaller than we actually are, we also underestimate how much we eat. Intake tends to be underreported by 10-40 percent according to a recent review of 59 studies, which compares people’s reports of intake to objective measures of the calories people need to eat to maintain weight (energy expenditure measured by doubly labeled water, which is the gold standard for assessing how many calories are spent).

Calorie undercounts are widespread, but studies show that overweight and obese people undercount to a greater extent.

Calories expenditure, however, is related to body mass – the larger you are the more calories you need, regardless of physical activity.

A new study including 221 people compared reported caloric intake with objective measures of energy expenditure using doubly labeled water, and also compared it to body size.

Overall, underreporting was very significant, and by as much as 1000 calories a day – had that been true people would be losing weight rather than staying the same weight or gaining some.

Obese people underreported caloric intake by as much as 42 percent. More active people also tended to underreport by almost as much: 41 percent. In comparison, thinner and more active people underreported – but by less.

But when you take into consideration body size and therefore resting energy expenditure, the absolute discrepancy between reported caloric intake and expenditure was equal: thinner people under-reported calorie intake less, but their caloric need is lower, therefore the absolute discrepancy between actual intake and caloric need was about the same.

Dietary patterns rather than calorie counts

Given the tediousness of counting calories, and the inaccuracy our self-assessed intakes, eating while counting perhaps isn’t serving us well. Regardless of the reasons why we tend to imagine we’re eating less and better than we actually are, our self deception allows us to gain weight over time.

The authors suggest that perhaps focusing on obesity-risky foods, such as high energy density foods, ultra-processed foods, foods with low fiber that cause little satiety, and sugary beverages, might better serve as dietary guidelines. Recommending a dietary pattern rather that focusing on specific foods and quantities can help curb overeating, especially since most of us are only partially aware of ourselves doing it.

Denial, again, is a natural coping mechanism, but it’s especially un-useful when interventions such as healthier eating and activity habits could have helped turn the tide.
