14 Common Foods That Can Mess With Your Metabolism

14 Common Foods That Can Mess With Your Metabolism


Many health-conscious individuals who watch what they eat forget about a very crucial bodily function known as the metabolism. Cutting calories isn’t enough to lose weight, as your metabolism needs to be functioning optimally at the same time.

The problem is that so much of what you may be eating regularly is messing up your metabolic rate and digestive system without you even realizing it!

Here are 14 common foods that can mess with your metabolism.

1.    Dairy

Dairy contains several different components that are less than helpful for many people’s metabolic rates. These include:

  • Casein, a kind of dairy protein that some individuals don’t digest or process well
  • Lactose, the sugar component of dairy that many have an intolerance to
  • Saturated fats, which can contribute to inflammation via molecules known as lipopolysaccharides

Dairy in small amounts can be healthy, but those who consume a lot of it and have a lactose or casein intolerance may find themselves struggling as their body, unable to digest those components properly, slows down the metabolic process. Full-cream dairy products have a lot of saturated fats on top of that, which exacerbates problems like bloating.



2.    Farmed Beef

In recent years, you’ve probably started hearing more and more about the benefits of grass-fed meat as opposed to factory-farmed meat. A lot of the statements surround animal rights and similar issues. We should take these valid considerations into account. However, a closer look provides you with a human health-related reason grass-fed meat is better.

Factory-farmed beef is made by giving the cows in question a lot of antibiotics. This approach has been the standard, acceptable farming method for decades, as antibiotics prevented the overcrowded cows from developing and spreading disease. Most thought nothing of it until a study, published in the Frontiers in Public Health journal, revealed that those antibiotics are harmful to us.

This research mostly showed that antibiotics could cause weight gain and digestive changes, as they may kill off the good gut bacteria that human beings need to process food. Meanwhile, grass-fed cows that aren’t kept in inhumane conditions don’t usually need those antibiotics for their farmers to make a profit, so grass-fed beef comes made without the metabolism-harming medicines.

3.    Alcohol and a Sluggish Metabolism

Alcohol is full of calories, and when you drink your calories, you’re less likely even to notice them. But it’s not just that trap that can get you stuck when it comes to alcohol – your body’s metabolic and digestive processes can suffer, too, because:

·         Blood Sugar

If you’ve ever noticed that after drinking a lot of alcohol, you don’t feel motivated to work out the next day and wind up craving sugary things, it’s because alcohol causes an imbalance of blood glucose.

·         Lowered Inhibitions

Lowered inhibitions mean that you don’t think as much about what you eat or drink, which can cause a lot of additional calories from unhealthy foods that further slow metabolism.

·         Research

According to a study in Current Obesity Reports, actions such as heavy drinking increase the risks of obesity. Though many factors are contributing to this, the bottom line is that those who drink a lot are also more prone to making poor decisions, for any variety of reasons.

metabolism4.    Sugary and Sweet Drinks

A lot of drinks have sugars in them. Even fruit juices and smoothies, touted as healthy, are packed with them, and “no-sugar” diet sodas are empty calories with artificial sweeteners that are just as harmful as sugar. The consumption of sweet dreams regularly links to numerous diseases, such as:

  • Insulin resistance
  • Obesity
  • Diabetes

But why do sugary drinks, in particular, do this? That’s because most use something called fructose in their sweetening efforts. High-fructose corn syrup, specifically, is what is used, providing 55% fructose (which is more than table sugar’s 50%). Fructose affects the digestive system and results in increased fat storage.

A study found that overweight individuals consuming drinks sweetened with fructose experienced less positive metabolisms than those who didn’t, and in fact, their metabolic rate dropped at a noticeable rate.

5.    Fast Food and Fried Food

These foods taste great, but they’re incredibly unhealthy – that’s why they’re commonly referred to as junk food and panned by health and diet experts. They contain trans fats in high amounts, typically impartially hydrogenated oils, and these oils can:

  • Facilitate weight gain, even with reasonable or “healthy” calorie consumption, when compared with those who don’t eat them
  • Clog up the digestive system, causing a significantly slowed metabolism
  • Increase the risk of abdominal obesity, according to a study published in the American Journal of Clinical Nutrition

6.    Omega-6 Fatty Acids

You’ve likely heard a significant number of good things about omega-3 fatty acids, which provide healthy fat to the body in an easy-to-digest and often nutritionally rich manner. But what about omega-6 fatty acids? Well, they’re excellent and sound to consume in moderation, but not too much.

Omega-6 fatty acids themselves aren’t harmful, but the fact that they’re effortless to find in oils and fats exacerbates the problem. This kind of fatty acid, when consumed in excess, can also cause inflammation that wreaks havoc on your metabolism, and it also increases the risk of developing insulin resistance, according to research.

Essentially, you need the right balance of omega-3 and omega-6 fatty acids to enjoy their benefits without significant repercussions. As such, make sure that your omega-6 fatty acid intake isn’t outdoing your omega-3 intake. You can find these omega-6 fatty acids in:

  • Pork
  • Cookies
  • Butter
  • Chicken Thighs
  • Sesame seeds
  • Pumpkin seeds
  • Firm tofu
  • Cured meat
  • Peanut butter
  • Junk foods

7.    Soybean Oil

Soybean oil is a prevalent ingredient in many different kinds of foods, so it’s difficult to avoid – and, therefore, all the more harmful. It is packed with:

  • Calories
  • Omega-6 fatty acids
  • Inflammatory components

Soybean oil has been found in studies to contribute to obesity, and it is the one component in the average American diet that has ruined the omega-3 to omega-6 ratio that would be healthy. It’s so high in omega-6 fatty acids that it can cause leptin resistance, which is a type of hormone that informs you when you feel full.

If you use soybean oil a lot, you can opt to switch to other options, such as flaxseed or olive oils, but remember to avoid eating foods where it is commonly used, such as in fried and processed foods.

8.    Granola and Granola Bars

Granola has been thought of as a healthy food for years, but unfortunately, the benefits of the oats used in them are completely drowned out by preservatives, sugar, and high-fructose corn syrup. Relying on them can result in an extremely slow metabolism, especially if you eat them in the morning.


9.    Traditional Yogurt

Greek yogurt is amazing for your metabolism. Traditional yogurt? Not so much. They don’t have nearly as much protein as the former does, so you lose out on an important nutrient that helps keep the metabolism up. Some traditional yogurts also use fruit puree, sugar, and artificial flavoring, loading you up on simple carbohydrates that cause blood glucose spikes.

10. Decaffeinated Coffee

If you drink decaf in the evenings, that’s fine, and you’re doing yourself a favor. But depriving yourself of caffeine and swapping out normal coffee for decaf isn’t typically a good idea. This is because the caffeine helps kick start the metabolism.

It’s okay if you have one cup of normal coffee a day and then opt for decaf from that point onwards, but don’t eliminate regular coffee unless you have an excellent reason to do so!

11. Refined Grain

Refined grains refer to foods such as white rice, white bread, white pasta, packaged food, and similar products. According to a 2011 New England Journal of Medicine study, individuals who consume refine drains gain .39 pounds per serving of refined grains they eat per day over years
