Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
3 studies reviewed
In plain English

In young people, insulin resistance and obesity develop as a result of long-term consumption of high-calorie, low-nutrient foods and low levels of physical activity.

See the scientific wording

Insulin resistance and obesity in youth are acquired conditions resulting from prolonged exposure to energy-dense, nutrient-poor diets and sedentary behavior.

Why this might work

Eating too many high-calorie, low-nutrient foods causes undigested starch and fiber to reach the gut, where they trigger the production of molecules that improve insulin response and reduce hunger. At the same time, sitting for long periods changes how fat tissue behaves, making it produce more stress hormones and disrupt insulin signaling. Together, these changes cause the body to store more fat around the organs, reduce energy use, and become less able to control blood sugar.

What the research says

3 studies

  1. Study: Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial

    This study showed that when people ate more potatoes and beans instead of junk food, they lost weight and their blood sugar control got better. This supports the idea that eating too many high-calorie, low-nutrient foods over time can cause obesity and insulin resistance.

  2. Study: Prediction of metabolic syndrome by a high intake of energy-dense nutrient-poor snacks in Iranian children and adolescents

    Kids who ate a lot of junk snacks like chips and candy were about three times more likely to develop health problems like obesity and insulin resistance than kids who ate很少这些零食, even when accounting for how much they exercised.

  3. Study: Sedentary behavior, physical activity, sleep duration and obesity risk: Mendelian randomization study

    This study found that kids and teens who spend more time watching TV, using computers, or driving are more likely to become obese, and it’s likely because of how their bodies are wired genetically. It didn’t find the same link for exercise or sleep, but it still supports the idea that sitting too much contributes to weight gain.
