To accomplish your weightloss goals, it's important to first get your head in the game. Being mindful of these common food biases is a great place to start.
Stereotyping Bias: We often classify foods as either vices or virtues and base choices solely on those stereotypes instead of nutritional value and calorie content.
Healthy hint: Not all healthy food is low in calories.
Balancing Bias: We mistakenly balance the intake of healthy and unhealthy foods, believing that we can cut calories simply by adding a healthy option.
Healthy hint: Add up—do not average—caloric intake.
Unit Bias: We often think of food in terms of units, meals and events and ignore the actual quantity consumed.
Healthy hint: Quantity of food consumed—how much we eat—is often more important that what we eat
Framing Bias: We are easily influenced by the context in which we evaluate our meals. The same meal can appear more or less healthy depending on the other available options.
Healthy hint: Consider each item by itself.
Comparison Bias: Our choices are swayed by comparisons; we think of the best available option as a good choice, even when it is not.
Healthy hint: Focus on merits of food, not on how much healthier it appears than the alternatives.
Consistency Bias: Our consumption behavior is inconsistent with our long-term weight-loss goals.
Healthy hint: Eat until you’re about 70 percent full.
Priority Bias: We give priority to other goals—saving money and time, seeking social approval and managing stress—while shortchanging our weightloss goals.
Healthy hint: Stay the course by controlling mindless habits. Think long-term; over the long run, small changes produce big results. And select actionable goals, fortifying your commitment to them by writing them down and sharing them.
