The Hidden Ingredient That Could Quietly Kill Your Cravings

When it comes to dieting, people will look for any advantage they can. Restricting calories is tough in the long run; your body will fight back and increase hunger levels in an attempt to get you to eat more.

Most would agree that the biggest obstacle in maintaining a diet is appetite. Even dealing with low energy levels is easier than the constant hunger.

A new study suggests that the type of food you eat could help curb hunger.

Researchers had 49 adults eat tortilla chips and salsa in a lab once a week for two weeks. One week the salsa was mildly spicy, the other week it was 4x spicier (more cayenne pepper). They measured how much food people ate and how fast they ate it.

When eating the spicier salsa, participants ate 28% less overall and 30% slower. The main takeaway is that spicier food slows you down, and eating slower naturally leads to eating less.

This makes intuitive sense; when something is spicy it's hard to eat it quickly, unlike sweet or salty snacks. Part of what makes dieting hard is that you eat so quickly that the body cannot send the "fullness" signal to the brain fast enough, leading to potential overeating.

What's interesting about cayenne pepper is that there is separate research showing it may have minor fat oxidation benefits. This is why you find it in certain fat burning supplements.

So next time you're reaching for a snack, it might be worth adding a little heat. A dash of cayenne on your eggs, a spicier salsa with your chips, or a pinch of chili flakes on your meal could be a surprisingly simple tool in your dieting arsenal.
