10 Signs You're Eating Too Much Sugar

Ever find yourself reaching for snacks constantly, feeling tired after meals, or struggling with unexplained weight gain? These could be your body's ways of saying you're consuming too much sugar. With rising concerns about sugar's impact on health, understanding these signals has never been more critical.

Autumn Bates, a certified clinical nutritionist with a master's in nutrition and human performance, helps thousands achieve their wellness goals through science-backed nutrition advice. Here are her expert tips on identifying signs of excessive sugar consumption combined with recent research findings.

You're Hungry Every Hour or Two

"Higher intakes of sugar cause blood glucose levels to spike and then quickly drop back down," Autumn explains. This rapid drop triggers hunger shortly after eating. If you constantly need backup snacks in your bag, excessive sugar might be the culprit.

Acne and Breakouts Appear Frequently

Recent studies have linked hyperinsulinemia (high blood insulin levels) to acne breakouts, Autumn notes. This condition isn't just caused by obvious sugars – refined carbohydrates like chips, pretzels, and pasta break down into simple sugars, triggering insulin spikes that can lead to skin issues.

Belly Fat Won't Budge

"High sugar intakes can cause insulin levels to skyrocket and cause fat storing to happen, especially around the belly," Autumn warns. This occurs because insulin not only prevents fat-burning but actively promotes fat storage when levels remain elevated.

Afternoon Sugar Cravings Hit Hard

Those 3 PM sugar cravings aren't random, according to Autumn. They're typically caused by blood sugar crashes from earlier sugar consumption, leading to cravings for more sugary or starchy foods to boost energy levels.

Persistent Thirst Despite Hydration

Constant thirst, even when drinking plenty of water, could indicate insulin resistance or pre-diabetes, Autumn cautions. This occurs when uncontrolled blood glucose levels cause increased urination, triggering persistent thirst.

Dark Skin Around Body Creases

Known as acanthosis nigricans, dark patches around the neck or armpits are serious signs of pre-diabetes or insulin resistance. "If you have this, make sure to check in with your doctor," Autumn strongly advises.

Frequent Bloating After Meals

"Bloating is typically a result of trapped gas within the intestines," Autumn explains. Sugar is highly fermentable by gut bacteria, especially fructose, which makes up half of table sugar and most of honey. Those with conditions like SIBO may be particularly sensitive.

You Get "Hangry" Often

The hunger-anger combination isn't just a mood issue. As Autumn describes, "During that dip in blood sugar, you're also going to experience mood swings," which can affect your relationships and daily interactions.

Multiple Skin Tags Appear

The presence of several skin tags could indicate insulin resistance or pre-diabetes. Autumn emphasizes the importance of medical consultation if you notice this symptom.

Weight Loss Seems Impossible

"Sugar is the number one driver of our storing hormone insulin," Autumn states. "When insulin is high, that fat-burning state is simply turned off," making weight loss extremely difficult regardless of diet and exercise.

The Science Behind Sugar's Impact

Research published in JAMA Internal Medicine reveals alarming cardiovascular risks from excess sugar. People consuming 17-21% of their calories from added sugar face a 38% higher risk of dying from cardiovascular disease compared to those limiting sugar to 8% of their calories. The Centers for Disease Control and Prevention (CDC) warns that excess sugar consumption can lead to insulin resistance, potentially resulting in type 2 diabetes, nerve damage, vision loss, and clogged arteries.

Know Your Limits: Daily Sugar Guidelines

The American Heart Association (AHA) provides clear daily sugar intake limits:

• Women: Maximum 100 calories (6 teaspoons/24 grams) of added sugar.
• Men: Maximum 150 calories (9 teaspoons/36 grams) of added sugar.

The CDC recommends keeping added sugars below 10% of your total daily calories for optimal health.

Cutting back on sugar is a powerful step toward better health and weight loss, but it’s not always straightforward. Many people unknowingly replace sugar with hidden sources, misunderstand nutrition labels, or make changes that feel unsustainable. These mistakes can sabotage your efforts and leave you feeling frustrated. By understanding the most common pitfalls and how to avoid them, you can successfully reduce sugar intake without sacrificing flavor or satisfaction. Here are the five biggest mistakes to watch out for when cutting back on sugar.

Replacing Sugar with Artificial Sweeteners

Artificial sweeteners might seem like a good alternative, but they can lead to unintended consequences. They often increase cravings for sweet foods and disrupt the body’s natural response to sugar. Instead, focus on naturally sweet options like fresh fruit, which provide fiber and nutrients along with sweetness.

Ignoring Hidden Sugars on Labels

Sugar hides in many processed foods under names like fructose, maltose, or cane syrup. Many “healthy” products like granola bars or yogurt contain added sugars that can derail your efforts. Always read nutrition labels carefully and opt for products with minimal or no added sugars.

Going All In Too Quickly

Eliminating sugar cold turkey can lead to withdrawal symptoms like headaches, irritability, and intense cravings. Instead, reduce sugar gradually to allow your body and taste buds to adjust. Start by cutting sugar in your coffee or swapping out sugary snacks for healthier options.

Skipping meals can lead to extreme hunger and a stronger desire for sugary foods later in the day. Balanced, protein-rich meals help keep your blood sugar stable and reduce cravings. Focus on whole, nutrient-dense meals to support your sugar-cutting efforts.

Not Planning Ahead for Snacks

Should you cut sugar out of your diet? Christina Hedges (@christina_hedges) is an influencer and online health coach with hundreds of thousands of followers across various platforms. In her videos, she teaches her followers about health habits and tips to help with everything from weight loss to improving digestion. In one viral video, she reveals how to “cut out the sugar” from your diet in just two weeks. We also enlisted the help of The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian to weigh in on her suggestions – and you might be surprised by her response.

Avoid All Simple and Most Complex Carbohydrates, She Recommends

“Disclaimer, this will be challenging and not for everyone,” she warms at the start of the clip. “Avoid all simple carbohydrates and most complex carbohydrates. For now, this includes fruits as they're high in sugar, except for avocados and berries,” she says.

Here Is Why Carbohydrates Are Bad, She Says

“Carbohydrates are glucose molecules put together differently. And as you know, the body has two forms of energy, fat, and carbohydrates,” she continues.

“So what can you eat here?” She suggests starting by drinking “plenty of water, avoiding soda, juice, and coffee with cream or sugar.”

She Suggests Eating These 12 Foods

She goes on to list “12 foods with little to no sugar,” starting with greens. “Organic kale with zero grams of sugar. Red meat such as beef, lamb, and organ meats with zero grams of sugar. Wild salmon with zero grams of sugar, chicken with zero grams of sugar, coconut oil, or extra virgin olive oil with zero grams of sugar. Pure butter with 0.1 grams of sugar per a hundred grams sauerkraut with 0.1 grams of sugar per ounce cheese with zero to 0.4 grams of sugar per ounce. Avocados with 0.4 grams of sugar eggs with 0.6 grams of sugar vegetables such as the ones listed above with zero grams of digestible carbs. Lastly, berries with four to 10 grams of sugar per a hundred grams,” she says.

RDN Disagrees and Calls This “Unsustainable”

Collingwood is not on board with Hedges’ advice. “This is not sustainable or healthy,” she says. “The diet recommended here is pretty strict and is eliminating entire food groups and way too low in carbohydrates to be healthy or sustainable.”

Cutting Out Added Sugar Is Fine

“Cutting out added sugar is fine and there is no negative to doing it other than just maybe going through some cravings at first,” she continues. “Cutting out all carbs and natural sugar can leave you with very little fiber (constipation and other digestive issues) and also will potentially leave you with very little energy.”

Is eating too many calories taking a toll on your health and wellness? “It takes about 20 minutes for your brain to send a signal to the stomach to let you know that you’re full. Overeating occurs when you continue to eat beyond this point of fullness,” research dietitian Erma Levy tells MD Anderson. Here are 15 signs and symptoms of eating too much food.

Low-Energy

Feeling sluggish after a meal could be a sign of overeating. “Overeating makes your body work harder and redirects blood flow away from other organs to your busy digestive system,” says the Cleveland Clinic. “This can make you feel tired or sluggish. The foods we’re more likely to overeat also tend to be higher in carbohydrates, which can cause a sugar rush followed by a sugar crash.”

Heartburn

Heartburn is a common symptom of eating too much. “To break down food, the stomach produces hydrochloric acid,” Levy explains. “If you overeat, this acid may back up into the esophagus resulting in heartburn. Consuming too much food that is high in fat, like pizza and cheeseburgers, may make you more susceptible to heartburn.”

Bloating

Eating too much food can cause bloating. “If you get a bloated stomach after eating, it may be a digestive issue,” says the Cleveland Clinic. “It might be as simple as eating too much too fast, or you could have a food intolerance or other condition that causes gas and digestive contents to build up.”

Poor Sleep

Eating too much can mess with your sleep. “Overeating can even impact your sleep,” Levy says. “Your circadian clock, which controls your sleep cycles, causes your sleep and hunger hormone levels to rise and fall throughout the day. Overeating can upset this rhythm, making it hard for you to sleep through the night.

Hot and Sweaty

Eating too many calories can lead to hot flashes and feeling sweaty. Eating spicy food can have the same effect as digestion increases body temperature.

Gas

Too many calories can cause digestive issues including gas. “Too much lower intestinal gas can be caused by eating too much of certain foods or not being able to fully digest certain foods,” says the Mayo Clinic. “It also can be from a change in the bacteria found in the colon.”

Nausea

Nausea could be a symptom of eating too much in one sitting. “Eating too much food can cause you to feel uncomfortable and nauseated,” Jenilee Matz, MPH, tells Walgreens. “When you overeat, the stomach expands to make room for excess food. The larger stomach can put pressure on nearby organs, which can cause discomfort. It may also lead to heartburn, gas and bloating, especially if the foods you ate were high in fat because they take longer to digest.”

Type 2 Diabetes

Eating too much can lead to type 2 diabetes. "Over the course of weeks to months to years, overeating can affect your cholesterol and could potentially impact your blood sugar management, which can put you at risk for developing type 2 diabetes and heart disease," wellness dietician Kylie Arrindell tells Houston Methodist.

Embarrassed About Food

Feeling depressed or distressed about food could be a result of overeating. “If you overeat, you may feel embarrassed or distressed after finishing a meal,” says UPMC Healthbeat. “People who overeat may feel that they lack control over what and how much they consume. A history of failed diets also could indicate that you struggle with overeating.”

Always Feeling Full

If you’re constantly snacking and never reach mealtimes genuinely hungry, you could be overeating. “Overeating occasionally will not make you gain weight overnight, but chronic bouts of excess eating are a different story,” Julia Zakrzewski, RD, tells Nourish. “These eating patterns can make it difficult for you to recognize your hunger and satiety cues.”

Heart Disease

Eating more calories than you need could lead to heart disease. “If you usually eat more calories than you can burn off, you raise your risk of gaining weight and storing more body fat,” according to UPMC Healthbeat. People who are overweight or obese have a higher risk of metabolic syndrome, a group of conditions linked to heart disease.”

Food Loses Taste

Foods that you once loved may not seem as nice anymore. “The meal no longer has the same appealing taste as your first bite,” Zakrzewski says.

Belly Fat

Excess belly fat is one of the signs of overeating. “That extra belly fat does more than just make it hard to zip up a favorite pair of jeans, though,” says the Mayo Clinic. “Research shows that belly fat carries serious health risks. People who regularly eat and drink more calories than they burn each day are more likely to gain extra weight, including belly fat.”

Binge Eating

“Frequent overeating may indicate binge eating disorder (BED),” says UPMC HealthBeat. “Common signs of BED include eating faster than normal, eating until you’re uncomfortably full, eating alone often, or consuming large amounts of food when you’re not hungry.”

Weight Gain

If overeating is causing uncontrollable weight gain, consider seeing a professional to help understand what might be causing it. “Whatever emotions drive you to overeat, the end result is often the same,” says the Mayo Clinic. “The effect is temporary, the emotions return and you likely then bear the additional burden of guilt about setting back your weight-loss goal. This can also lead to an unhealthy cycle — your emotions trigger you to overeat, you beat yourself up for getting off your weight-loss track, you feel bad and you overeat again.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.
