Potential Signs You’re Eating Too Much Sugar
Sugar gets a bad rap, but the truth is that it’s a vital source of energy and essential to our survival. Of course, not all sugars are the same. Fructose found in fruits and vegetables and lactose in dairy-rich foods are natural sugars we don’t have to be as concerned about because these foods also have fiber and calcium, for example. Added sugars, however, which are often found in processed foods, are those we could do without, and most of us consume too much of them.
According to the Dietary Guidelines for Americans 2020–2025, the average American consumes 270 calories of added sugars, or 17 teaspoons, each day.

Added sugars are anything that’s added to food to make it taste sweet, and this includes natural sugars like honey and maple syrup. “Even though they may be more wholesome than table sugar, it’s still contributing more calories but not much in the way of vitamins and minerals,” says Jessica Cording, RD, a health coach in New York City and author of The Little Book of Game Changers.
Sugar is sneaky and can hide under 61 different names, according to the University of California in San Francisco. Despite your best efforts to make healthy food choices, you could be getting more sugar than you bargained for.
Negative Effects of Sugar on the Body
Per Harvard Health Publishing, when we eat sugar, most of it gets broken down and absorbed in the small intestine. Specialized enzymes attack larger molecules and convert them into three simpler sugars: glucose, galactose, and fructose. The liver and muscles store some of the glucose as glycogen, a molecule that can be turned back into glucose when your body needs it.
When glucose enters the bloodstream, however, levels of blood glucose rise. In response, the pancreas secretes insulin to help glucose get where it needs to go in your body. If you’re consuming large amounts of added sugar, the cells can become resistant to insulin over time — a risk factor for systemic inflammation, type 2 diabetes, and other chronic conditions.
According to a study published in November 2016 in the journal Nutrients, consuming too much added sugar has also been linked to weight gain and obesity, risk factors for heart disease, nonalcoholic fatty liver disease, and cancer.
“Excessive intakes of added sugars impact our energy, mood, weight, and disease risk,” Cording says. “Across the board it can impact our physical and mental well-being.”
“In order for us to function as smoothly and as normally as possible, we need our blood sugar to be operating in the Goldilocks zone of energy,” says William W. Li, MD, a physician in Cambridge, Massachusetts, and author of Eat to Beat Disease.

Are You Eating Too Much Sugar?
The recommendations for limits on added sugars vary among industry groups. The Dietary Guidelines for Americans 2020–2025, which are published by the U.S. Department of Health and Human Services and U.S. Department of Agriculture, recommend limiting calories from added sugars to no more than 10 percent each day. For someone who consumes 2,000 calories a day, that’s a maximum of about 12 teaspoons worth.
The American Heart Association, however, recommends limiting the amount of daily added sugars to no more than 100 calories for women and children and 150 calories for men. That works out to be about 6 teaspoons for women and children and 9 teaspoons for men.
Both groups agree that toddlers and infants under 2 shouldn’t consume any added sugars.

If you’re not getting enough fruits and vegetables in your diet and not eating balanced meals made up of lean protein, healthy fat, and unrefined carbohydrates, it’s possible that added sugars may be displacing other good-for-you foods. Not only are you likely missing out on vitamins, minerals, and fiber but all that added sugar could manifest itself in other surprising ways.
1. Increased Hunger and Weight Gain
If you’re consuming a lot of extra calories through added sugars, increased hunger is one of the first signs. “[Sugar] is satisfying to the taste buds, but it doesn’t really satisfy or fill our stomachs,” Keri Stoner-Davis, RDN, who works at Lemond Nutrition in Plano, Texas. Sugar abuse usually lead to tooth decay and other unhealthy oral conditions, prevent most of them by reading the latest dentitox pro reviews.
Without protein, fiber, and healthy fats, which most processed snacks and sugary treats lack, the body burns through sugar quickly and ramps up hunger, which can lead to mindless and even compulsive snacking, Cording says.
According to a review and meta-analysis, consumption of sugar-sweetened beverages promotes weight gain in adults and children.
Yet it’s not only the extra calories that can increase weight.
The gut microbiome, an ecosystem made up of 39 trillion microorganisms, is the body’s self-defense system, according to an article published in May 2016 in Cell. A healthy gut helps our metabolism regulate blood glucose and insulin levels and, in part, enables our bodies to use lipids and manage cholesterol. “When you have added sugar, it damages that ecosystem,” Dr. Li says.
Good bacteria decrease and bad bacteria overgrow, leading to dysbiosis (an imbalance between these bacteria) as well as problems with metabolism and the ability to properly process lipids and cholesterol.
What’s more, sugar may damage our fat hormones, including leptin, which inhibits hunger, Li argues. “High sugar disrupts metabolism, in part by interfering with leptin,” according to Li. “Eating sugar makes you want to eat more sugar, which makes you more hungry.”

If you’re feeling moody, irritable, or on edge, stress may not be the only reason — it could be a sign that you’re eating too much sugar.
A study published in January 2020 in the journal Medical Hypotheses suggests that eating added sugars can promote inflammation, worsen mood, and lead to symptoms of depression.
A high-sugar meal or snack without protein and fat quickly spikes your blood sugar, but as your body rushes to process all of it, your energy levels crash, making you feel sluggish and irritable, Cording says.
Also, when there’s low glucose in the bloodstream because your insulin levels have spiked after eating a lot of added sugar, levels of blood glucose in the brain decrease as well. “Our brains are absolutely critically dependent on having a normal level of blood sugar to fuel them,” Li says.
The important thing is to pay attention when you’re feeling off. For example, if you start to feel irritable an hour after you eat a snack or at the same time every day, excess sugar could be to blame. “If you notice that’s happening to you a lot, it’s a good opportunity to take a look at what you’re eating,” Cording says.
3. Fatigue and Low Energy
Sugar is easily absorbed and digested, so if you’re feeling fatigued, it could be due to the amount of sugar you’re getting in your diet.
“Sugar is a very quick energy source, so regardless of how much you eat, in 30 minutes you’re going to be hungry again, low on energy, or looking for energy again,” Stoner-Davis says.
Large swings of blood sugar and insulin can also cause energy levels to plummet and affect your overall energy level, Li says.
4. Foods Don’t Taste Sweet Enough
If you’ve noticed that foods don’t taste as sweet as they used to, or if you need to add sugar to foods to make them taste good (think: dusting your cereal with brown sugar), it could be that you’re getting too much sugar to begin with.
If you’re trying to make healthier choices, say by switching from flavored yogurt to plain yogurt, the difference will be more noticeable.
“You train your brain to expect a very high level of sweetness, and when you’re used to that, it can be harder to feel satisfied with foods that are less sweet because you’re primed to expect the high sweet levels,” Cording says.
If you’re replacing sugar with artificial sweeteners in your diet, you may also want to give it a second thought. “A lot of these sugar substitutes are so much sweeter than actual sugar so it tricks our brains into expecting this insanely high level of sweetness,” Cording says. This can increase sugar cravings overall.
5. Cravings for Sweets
If you’re craving sweets, you may be addicted to the feel-good effects that sugar has on your brain. Sugar targets the brain’s pleasure center (called the mesocorticolimbic pathway), triggering a rise in the so-called “happy hormone” dopamine, Cording says.
This pathway in the brain plays a significant role in the food choices we make, including affecting cravings for sugar.
Put simply, eating sugar increases dopamine, and the dopamine rise itself can increase cravings for sugar, leading to a vicious cycle, according to research.
The good news is that focusing on small meals and snacks comprised of real, whole foods, and eating regularly, can help those cravings improve, Stoner-Davis says.
