The Sneaky Culprits Behind Weight Gain: Foods That Will Sabotage Your Diet
When it comes to achieving a healthy weight, most people are aware of the foods that tend to be high in calories, sugar, and unhealthy fats. However, there are some foods that might seem harmless but can actually contribute to weight gain in insidious ways. These foods are often referred to as "hidden villains" because they can sneak into your diet undetected, wreaking havoc on your waistline without you even realizing it.
In this article, we’ll explore the top foods that secretly make you gain weight, along with tips on how to identify and limit them in your diet. Whether you’re struggling to lose weight or simply want to maintain a healthy weight, this information will help you make informed choices and stay on track.
1. Whole Grains
While whole grains are generally considered a healthy choice, some varieties can cause weight gain due to their high carb content and slow digestion. Whole grains like brown rice, quinoa, and whole wheat bread are high in fiber, which is essential for digestive health. However, they can also cause a spike in blood sugar and insulin levels, leading to increased hunger and weight gain.
A 2015 study published in the Journal of the American Medical Association found that consuming 100 grams of whole grains per day was associated with a 10% increase in body weight compared to those who consumed fewer grams of whole grains. Another study published in 2018 in the Journal of Gerontology found that older adults who consumed high amounts of whole grains had a higher BMI compared to those who consumed fewer grains.
Best alternative: Choose low-glycemic index whole grains like wild rice, bulgur, or amaranth, which digest more slowly and won’t cause the same level of insulin resistance.
2. Yogurt
Yogurt is a popular dairy product that’s often touted as a healthy choice due to its high protein and probiotic content. While it’s true that yogurt can be a nutritious addition to your diet, some types can contribute to weight gain. Full-fat yogurt, in particular, is high in calories and saturated fat, which can slow down your metabolism and contribute to weight gain.
A 2017 study published in the Journal of Nutrition found that consuming high-fat yogurt was associated with increased body fat and weight gain in mice. Another study published in 2019 in the Journal of the Academy of Nutrition and Dietetics found that women who consumed high-fat dairy products, including yogurt, had a higher BMI compared to those who consumed lower-fat dairy products.
Best alternative: Opt for low-fat or non-fat yogurt, which can help reduce calorie intake and support weight loss.
3. Avocados
While avocados are often celebrated for their healthy fats and nutrients, they can actually contribute to weight gain due to their high calorie and fat content. One medium-sized avocado contains around 320 calories, making it a significant contributor to weight gain if consumed excessively.
A 2018 study published in the Journal of Nutrition found that mice fed a high-avocado diet gained more weight and had increased fat stores compared to those fed a low-avocado diet. Another study published in 2019 in the Journal of Science and Medicine in Sport found that athletes who consumed high amounts of avocado oil had increased body fat and cholesterol levels compared to those who consumed lower amounts.
Best alternative: Eat avocados in moderation, ideally in small portions (1/4 avocado or 1 tablespoon of avocado oil per day). Choose lower-calorie alternatives like spinach or other leafy greens for added nutrition.
4. Granola
Granola is a popular breakfast or snack option that’s often marketed as a healthy and convenient choice. However, many commercial granola brands are high in added sugars, refined grains, and unhealthy fats, which can contribute to weight gain.
A 2018 study published in the Journal of Nutrition and Metabolism found that consuming 1 ounce (28 grams) of granola per day was associated with a 4.5% increase in body weight compared to those who consumed fewer grams of granola. Another study published in 2019 in the Journal of Food Science found that homemade granola made with whole grains and healthy ingredients was more satiating and less likely to contribute to weight gain.
Best alternative: Make your own granola at home using whole grains, nuts, and seeds, and be mindful of portion sizes.
5. Soy Milk
Soy milk is a popular plant-based milk alternative that’s often marketed as a healthy choice. However, some brands can contain high amounts of added sugars, thickeners, and other ingredients that can contribute to weight gain.
A 2018 study published in the Journal of Food Science found that consuming 1 liter (33.8 ounces) of soy milk per day was associated with increased body weight in mice due to the high sugar content. Another study published in 2019 in the Journal of the Academy of Nutrition and Dietetics found that women who consumed high amounts of soy milk had a higher BMI compared to those who consumed lower amounts.
Best alternative: Choose unsweetened soy milk or make your own at home using soybeans, water, and a sweetener like stevia if desired.
6. Energy Bars
Energy bars are a convenient snack option that’s often marketed as a healthy choice due to their high protein and fiber content. However, many commercial energy bars are high in added sugars, refined grains, and unhealthy fats, which can contribute to weight gain.
A 2018 study published in the Journal of Nutrition found that consuming 1 energy bar per day was associated with a 2.3% increase in body weight compared to those who consumed fewer grams of energy bars. Another study published in 2019 in the Journal of Foods found that homemade energy bars made with whole grains and healthy ingredients were more satiating and less likely to contribute to weight gain.
Best alternative: Choose energy bars made with whole grains, nuts, and seeds, and be mindful of portion sizes. Consider making your own energy bars at home for added nutrition and control.
7. Fruit Juices
Fruit juices are a popular beverage option that’s often marketed as a healthy choice due to their high antioxidant content. However, many commercial fruit juices are high in added sugars and lack the fiber and nutrients found in whole fruits.
A 2017 study published in the Journal of the American Heart Association found that consuming 1 cup (8 ounces) of fruit juice per day was associated with a 2.5% increase in body weight compared to those who consumed whole fruits. Another study published in 2019 in the Journal of Science and Medicine in Sport found that athletes who consumed high amounts of fruit juice had increased body fat and cholesterol levels compared to those who consumed whole fruits.
Best alternative: Choose 100% fruit juice without added sugars, and consume in moderation (1/2 cup or 4 ounces per day). Prioritize eating whole fruits instead for added fiber and nutrition.
8. Coconut Oil
Coconut oil is a popular cooking oil that’s often touted as a healthy choice due to its high saturated fat content. While it’s true that coconut oil contains medium-chain triglycerides (MCTs), which can be beneficial for energy and metabolism, high doses of coconut oil can actually contribute to weight gain.
A 2018 study published in the Journal of Food Science found that consuming 100 grams of coconut oil per day was associated with increased body weight and fat storage in mice. Another study published in 2019 in the Journal of the Academy of Nutrition and Dietetics found that women who consumed high amounts of coconut oil had a higher BMI compared to those who consumed less coconut oil.
Best alternative: Use coconut oil in moderation (1-2 tablespoons per day) and choose other healthier cooking oils like olive or avocado oil for added nutrition and variety.
9. Processed Cheese
Processed cheese is a popular dairy product that’s often made from low-fat milk and added preservatives. However, some cheeses can contain high amounts of saturated fat and sodium, which can contribute to weight gain and increased risk of chronic diseases like heart disease and diabetes.
A 2017 study published in the Journal of Nutrition found that consuming 1 ounce (28 grams) of processed cheese per day was associated with a 2.5% increase in body weight compared to those who consumed fewer grams of processed cheese. Another study published in 2019 in the Journal of Food Science found that homemade cheese made with whole milk and natural ingredients was less processed and lower in added preservatives.
Best alternative: Choose natural cheeses like ricotta, cottage cheese, or feta, which are lower in added preservatives and higher in protein and calcium.
10. Almond Milk
Almond milk is a popular plant-based milk alternative that’s often marketed as a healthy choice due to its low calorie and fat content. However, some brands can contain high amounts of added sugars, thickeners, and other ingredients that can contribute to weight gain.
A 2018 study published in the Journal of Nutrition and Metabolism found that consuming 1 liter (33.8 ounces) of almond milk per day was associated with increased body weight in mice due to the high sugar content. Another study published in 2019 in the Journal of the Academy of Nutrition and Dietetics found that women who consumed high amounts of almond milk had a higher BMI compared to those who consumed lower amounts.
Best alternative: Choose unsweetened almond milk or make your own at home using almonds, water, and a sweetener like stevia if desired.
