If you often turn to quick, processed dinners after a long day, you’re not alone — but experts warn that some of these convenient meals could be doing more harm than good. While they may save time, many processed dinner options are loaded with sodium, unhealthy fats, and refined carbs that can slow your metabolism and contribute to weight gain over time. Nutritionists are now calling out the worst offenders you should cut from your routine immediately if you want to support a healthier, more energized body.
The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles
1. Frozen Pizza
Frozen pizza is a prime example of an empty-calorie dinner, packed with refined carbohydrates, unhealthy fats, and excessive sodium but lacking in essential nutrients like vitamins, minerals, and fiber. The high levels of refined flour and sugars in the crust can lead to rapid spikes and crashes in blood sugar, disrupting your metabolism.
"Frozen pizzas are a quick dinner, but they can impact your metabolism due to their high content of refined carbohydrates and saturated fats. The crust can cause blood sugar levels to spike and drop, potentially leading to insulin resistance over time, which leads to excess fat storage. The saturated fats from cheese and processed meats can also increase the body's fat storage, making it harder to burn calories," says Michelle Saari, RD at EHealth Project.
2. Fast Food
Fast foods often qualify as empty-calorie dinners due to their high content of unhealthy fats, sugars, and refined ingredients, coupled with a lack of essential nutrients. Common items such as burgers, fries, and sugary sodas deliver a lot of calories without the nutritional benefits needed for a healthy diet.
"Fast food meals are made with high amounts of fat, sodium, and unhealthy oils. This can also lead to weight gain, obesity, cardiovascular disease, heart disease, and stroke, to name a few things," Jesse Feder, RDN, CPT at My Chrons and Colitis Team, states. "The ingredients in fast food meals are also highly processed and refined, which can be digested quickly and leave you with a decreased metabolism." To maintain a healthy metabolism and overall well-being, consider healthier alternatives.
3. Low-fat frozen dinners
You’ll notice that many low-fat meals are marketed as weight loss friendly, but the ingredient list is jam-packed with names you won’t even be able to pronounce. While low in calories, these meals are often stripped from important nutrients such as protein, fiber, healthy fats, and complex carbs. Most of these ingredients contain processed carbs and other additives that may not even fill you up.
Feder elaborates and says that "low-fat frozen dinners are marketed as healthy dinners; however, they still contribute high amounts of sodium and preservatives and are usually not satiating enough to only have one. This can lead to overeating, increases in weight, and inflammation throughout the body."
If parting ways with these meals is difficult for you, it's a good idea to always read the food labels and choose options with minimal processed ingredients.
4. Frozen Pasta Dishes
Frozen pasta dishes, while convenient, can be associated with bloating and the potential for belly fat accumulation. Many frozen pasta meals are high in refined carbohydrates, which can cause spikes in blood sugar levels, leading to increased insulin production and, in turn, promoting fat storage, particularly around the abdominal region.
Krutika Nanavati, a registered dietitian and nutritionist, shares, "frozen pasta dishes are often high in sodium, similar to frozen pizzas. A serving can contain over 600mg of sodium, significantly exceeding the RDI. Frozen pasta dishes typically use delicate pasta, which is low in fiber and nutrients. This type of pasta can cause blood sugar spikes and crashes, leading to overeating and potential weight gain."
Creamy pastas are some of the most popular options, but even the consistency can pack on calories. "Many frozen pasta dishes are prepared with creamy sauces high in fat and calories. These sauces can contribute to bloating, discomfort, and potential weight gain."
Instead, Nanavati says you should opt for frozen meals such as lean protein dishes, vegetarian, and stir-fries.
However, make sure to read the labels since a lot of these healthier frozen meals can have sneaky additives and processed ingredients which can affect bloating and weight gain.
