Related Episodes for How Ultra-Processed Foods Promote Overeating

“A 2022 Environmental Working Group analysis reported that 756 of 766 new food chemicals added from 2000 through 2021, or 98.7 percent, entered through industry GRAS determinations rather than the ordinary FDA premarket food-additive approval process.”

“The menus were matched for presented calories, energy density, total sugar, sodium, and fiber, but not added sugar: much more of the ultra-processed diet's sugar was added rather than contained in fruit. Protein was also only approximately matched, at about 14% versus 15.6% of calories.”

“But ultra-processing typically removes many nutrients while adding a plethora of chemicals meant to color, flavor, and preserve the food. In this Aliquot, I explain the science behind the risks associated with eating processed foods and offer advice on choosing healthier options.”

“From the chemistry of synthetic vanillin to the regulatory loopholes behind GRAS labeling, we explore how these additives can influence health—not just through potential toxicity, but by activating the brain's reward system in ways that may affect behavior.”

“In this Aliquot, I explain why visceral fat behaves so differently from other fat, how it drives insulin resistance and chronic disease, and what research shows about the most effective ways to reduce it.”

“Time-restricted eating can help some people reduce eating opportunities, although a 12-month trial found no additional weight or body-fat benefit when an eight-hour eating window was added to calorie restriction. Sleep also affects appetite and fat distribution.”

“Together, these examples make food-contact materials a practical place to examine everyday exposure, while the amount absorbed and the health effects of specific drinking habits remain active research questions.”

“A staggering 60% of all calories Americans consume come from ultra-processed foods that fail to induce proper satiety, remain cheaper than whole foods, and hijack our dopamine reward pathways, pushing us to overeat, incentivizing unhealthy food choices, and reinforcing addictive eating behaviors.”

“Regular exercise can improve insulin sensitivity and reduce visceral and liver fat, making sustainable food quality, energy balance, physical activity, and sleep practical long-term targets for metabolic health.”

“In this clip from Q&A #70, Dr. Rhonda Patrick organizes cancer prevention around the largest modifiable foundations: avoid tobacco, maintain a healthy body composition, and stay physically active.”
