In the world of snacks, not all options are created equal. While convenient and tempting, some snacks can wreak havoc on our metabolism and overall health, leading to issues like insulin resistance and a sluggish metabolism. These “worst snacks” often come disguised as innocent treats, packed with refined sugars, unhealthy fats, and processed ingredients that spike our blood sugar levels and wreak havoc on our body’s ability to regulate insulin.

We spoke with Krutika Nanavati, a registered dietitian and nutritionist, to learn about the two worst snacks to cut out because they cause insulin resistance and disrupt your metabolism. Nanavati revealed that snacks such as sugary energy bars and snack crackers are the ones to avoid. Read on to learn more.

Sugary Energy Bars

Nanavati shares that granola bars, fruit bars, and any sugary energy bar that are often marketed as healthy snack options may not provide as much nutritional value as you think. She adds that they have "added sugars, refined grains, [and] artificial sweeteners." Morever she notes how these processed snacks can harm your metabolism and cause insulin resistance.

"Excess sugar intake can cause rapid blood sugar spikes, leading to the pancreas releasing too much insulin. This can result in insulin resistance over time, making it harder to regulate blood sugar effectively. Refined grains, low in fiber, can worsen blood sugar spikes and digestive issues. Artificial sweeteners may disrupt gut bacteria and affect metabolic balance. Being mindful of these factors is important for optimal blood sugar regulation and overall health," she says.

Snack Crackers

Convenient processed crackers such as pretzels, chips made from potato, corn, or tortilla usually contain refined grains, high sodium, and unhealthy fats.

Nanavati elaborates on this further and says, "Similar to sugary snacks, crackers made with refined grains lack fiber and can cause blood sugar spikes. Consuming excessive sodium can lead to water retention and high blood pressure, straining metabolism. Unhealthy fats like partially hydrogenated oils found in crackers promote inflammation and disrupt gut health, impacting overall metabolic function."
