Show 1463: Why We Eat Too Much and What to Do About It

Описание: Obesity is a big problem in the US. The National Institute of Diabetes and Digestive and Kidney Diseases says 2 out of every 5 American adults are obese. What’s more, one in three is overweight, with only about 25 percent of us at a healthy weight. It’s not just adults; children are increasingly suffering weight problems as well. In this episode, we ask why we eat too much and what we can do about it.

Why We Eat Too Much:



Excess weight puts people at risk for premature death from cardiovascular disease, kidney problems and diabetes. Unfortunately, the standard advice from physicians to eat less and exercise more hasn’t often been very helpful. That’s because it doesn’t take into account the reason we eat too much: we are hungry. There are at least three different types of hunger that we need to consider, though.



Most people are familiar with homeostatic hunger. If you haven’t eaten for hours, your stomach may grumble and complain. There is also hedonic hunger–eating because something tastes delicious. That’s why you can usually find room for dessert, regardless of how much dinner you’ve eaten. Hedonic hunger is often linked to emotional eating because you feel bored or stressed or depressed. The third type of hunger is conditioned hunger. Think of Pavlov’s dogs, who learned to salivate in expectation of food when they heard a bell. Some people react much the same way when they hear a dinner bell, or when lunchtime arrives, or when they get in the car. If you are accustomed to eating then, you’ll expect food and become disappointed if it isn’t available.



But conditioned hunger can be addressed by deliberately changing your patterns. Set up the environment so the food is not so readily available at the times you have become conditioned to eat. Hedonic hunger yields best to figuring out the emotional basis for why we eat too much: boredom, stress, some other feeling. What other activities can help you cope with those feelings? For some people, it might be going for a walk. Others might find a different approach more helpful.

How Do Weight Loss Drugs Make Us Not Eat Too Much?



The most popular drugs on social media and in ads lately are the GLP-1 receptor agonists. That’s a fancy name for weight loss drugs like semaglutide (Wegovy) and tirzepatide (Zepbound). These medicines blunt the reward center in the brain that responds to food and drives some people to eat too much. They do that by mimicking satiety hormones, essentially telling our bodies “You’ve had enough.” They work pretty well for most people, at least in the short term. However, unless people retrain themselves regarding eating cues (for conditioned hunger) or emotional needs (for hedonic hunger), they are likely to gain the weight back when they stop taking the medication. For homeostatic hunger, making sure to get adequate protein and fiber in every meal can help. That tactic might not be very useful for hedonic hunger, though.



Are you addicted to ultra-processed foods? That can be a challenge. On the other hand, many people who are addicted to nicotine do find ways to overcome that addiction. It is possible to overcome junk food addiction, too. Dr. Fung describes his patient Harry who used fasting, eating carbohydrates last instead of first in the meal, along with some acid such as vinegar, and was successful in losing weight and feeling better. The most important thing Harry did was to use social support from his friends. Social and environmental factors are critical in the development of obesity, so they are also paramount in overcoming it.

Practical Advice to Help Us Not Eat Too Much:



How do you stock up on what you need and avoid what you don’t need at the supermarket? The usual advice is to shop the perimeter, where the fresh food like vegetables, fruit, eggs, meat and dairy products are located. The ultra-processed stuff is usually in the center aisles. You also want to read labels. If that food has ingredien...
