Why Do Carbs Make You Hungry

author avatar Dr. Eric Berg 05/23/2024

Ever wonder why you feel ravenous after a big plate of pasta or a few slices of white bread? You're not alone. It’s like there's this mysterious force driving us to snack more, especially on carb-heavy foods.

The culprit behind this is often misunderstood but crucial for anyone interested in health and nutrition. It's all tied to blood sugar spikes and drops caused by eating carbs—especially those refined ones like French fries and ice cream that we love so much.

Understanding why carbs make us hungry can help you manage your diet better, whether you're aiming for weight loss, exploring intermittent fasting, or just curious about how food affects your body.

The Role of Insulin in Hunger

Have you ever wondered why you feel hungry soon after eating a big plate of pasta or french fries? The answer lies in understanding how insulin affects our hunger and appetite, which is crucial to comprehending why carbs make us hungry.

When we eat carbs, our body breaks them down into glucose, which enters the bloodstream. In response, the pancreas releases insulin to remove the glucose from the blood and convert it into stored sugar in the liver and muscles.

This process can lead to fluctuations in blood sugar levels, triggering hunger.

Insulin Spikes and Blood Sugar Levels

Consuming carbs, especially refined carbs like white bread and sugary snacks, causes rapid spikes in blood sugar followed by quick drops. These fluctuations in blood glucose levels can increase hunger and cravings for more carbs.

In fact, a study published in the American Journal of Clinical Nutrition found that high-glycemic foods, which cause sharp increases in blood sugar, led to increased hunger and a greater desire to eat compared to low-glycemic foods.

Chronic Carb Consumption and Insulin Resistance

Consuming a lot of carbohydrates over time can lead to insulin resistance, a condition in which the body's cells become less responsive to insulin.

As a result, the pancreas has to produce more insulin to manage blood sugar levels, perpetuating a vicious cycle of high insulin levels and constant hunger.

Glycemic Index and Its Impact on Hunger

The glycemic index (GI) is a measure of how quickly a food raises blood sugar levels. Foods with a high GI, such as white bread and sugary snacks, cause rapid spikes in blood sugar, while low-GI foods, like complex carbs with fiber, result in a slower, more gradual rise.

High Glycemic Index Foods

High-GI foods cause faster insulin spikes and greater drops in blood sugar, leading to increased hunger. These foods are often low in fiber and nutrients, leaving you feeling unsatisfied and craving more.

A study published in the Journal of Nutrition and Metabolism found that consuming high-GI foods led to increased hunger and a greater desire to eat compared to low-GI foods, even when the calorie content was the same.

Fiber-Rich Carbs

On the other hand, complex carbs with fiber, such as sweet potatoes and brown rice, have a lower GI and help maintain stable blood sugar levels. These foods are more satisfying and can keep you feeling full longer, reducing the likelihood of overeating.

Fiber slows down glucose absorption into the bloodstream, preventing rapid insulin spikes and subsequent drops in blood sugar. You can better manage your hunger levels and maintain a healthy weight by choosing fiber-rich carbs over refined carbs.

Nutrient Density vs. Empty Calories

The nutrient content of our food significantly impacts our feelings of fullness and overall hunger levels. Empty carbohydrates, such as refined carbs and sugary foods, stimulate appetite due to their lack of nutrients, while nutrient-dense foods can help satisfy hunger.

Refined Carbs and Sugary Foods

Foods like white pasta and ice cream are low in nutrients but high in calories, leading to increased food cravings. These empty calories do little to nourish the body, leaving you feeling hungry and unsatisfied.

A study published in the American Journal of Clinical Nutrition found that consuming a diet high in refined carbs and added sugars increased hunger and a greater desire to eat compared to a diet rich in whole foods.

Nutrient-Dense Alternatives

On the other hand, choosing foods rich in vitamins and minerals can help reduce hunger by providing the body with the essential nutrients it needs.

Lowering fatty foods and consuming nutrient-dense options, including vegetables, seafood, and organic meats, can help satisfy hunger and promote overall health.

By focusing on nutrient density over empty calories, you can better manage your hunger levels and maintain a healthy weight.

Incorporating a variety of whole foods into your diet can provide the nourishment your body needs to function optimally and reduce unnecessary cravings.

Frequency of Eating and Its Effects on Appetite

How often we eat can influence our insulin levels and appetite regulation throughout the day. Frequent eating triggers insulin release, regardless of the type of food consumed, leading to a greater appetite.

Frequent Snacking

Eating small meals or snacks can elevate insulin levels, perpetuating feelings of hunger. Even low-fat or lean protein can stimulate insulin and increase appetite, while fat satisfies hunger.

A study published in the British Journal of Nutrition found that consuming three larger meals per day led to greater feelings of fullness and reduced hunger compared to consuming six smaller meals, even when the total calorie intake was the same.

By being mindful of your eating frequency and choosing satiating foods, you can better manage your appetite and avoid constant hunger pangs. Incorporating healthy fats and protein into your meals can help keep you feeling full and satisfied throughout the day.

The Importance of Fat in Satisfying Hunger

Dietary fat plays a critical role in signaling satiety to the brain and reducing overall hunger levels. Adequate bile production is necessary for extracting fat-soluble nutrients that satisfy the body and signal the brain to stop eating.

Bile Production for Nutrient Absorption

Proper bile production helps extract nutrients from fats that signal fullness to the brain. When we consume healthy fats, such as those found in avocados, nuts, and olive oil, our body releases hormones that tell us we're satisfied and can stop eating.

Fasting can also switch the body's metabolism to running on its own fat stores, reducing hunger and improving insulin resistance.

By incorporating healthy fats into our diet and practicing intermittent fasting, we can better manage our hunger levels and maintain a healthy weight.

By understanding these various factors—insulin's role in managing blood sugar levels, the impact of glycemic index on hunger, the importance of nutrient density over empty calories,

how eating frequency affects appetite, and the critical role dietary fat plays—we can better manage our carb intake to avoid unnecessary hunger pangs.

This comprehensive approach helps maintain stable energy levels throughout the day while supporting overall health.

Carb Cravings Unveiled

Carbohydrates, particularly refined ones, trigger rapid spikes and subsequent crashes in blood sugar levels, leading to a cycle of hunger and overeating.

When we consume carbs, our body releases insulin to manage the increased glucose, but this can cause a swift drop in blood sugar, making us feel hungry again soon after.

This rollercoaster effect often results in craving more carbs to restore energy levels. Switching to a low-carb, high-protein alternative like keto chicken tenders can help stabilize blood sugar and keep hunger at bay.

By focusing on nutrient-dense, satisfying foods like keto chicken tenders, you can break the cycle of carb-induced cravings and maintain a more balanced appetite.


The reality is simpler yet profound: Consuming certain types of carbs triggers insulin spikes followed by sudden drops in blood glucose levels—leaving you hungrier than before.

Your daily battle with carb cravings isn’t some Hollywood horror story but a biological response rooted deeply within our systems since the 60s when these insights first emerged.

So next time hunger pangs hit hard post-pasta binge remember—it’s science at work!
