In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
"Anytime you’re stressed, you probably go for food," Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
8. Find friends with similar goals. Obesity can be “contagious,” meaning you could gain weight if you hang out with people who are obese, suggests a 2007 study published in The New England Journal of Medicine. That’s not to say you should give someone the cold shoulder because of their weight. But keep in mind that your peers have an influence on the choices you make, Bowden says. Surround yourself with friends who enjoy getting active (like the ones who think a 10-mile hike on the weekend is a good time).
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
Researchers from the University of Cambridge looked at 72 studies and found that people consistently consume more food and drink when they are offered larger-sized portions, packages, or tableware than when offered smaller-sized versions. The data suggested that if larger portions and tableware were eliminated throughout the diet, Americans could save about 527 calories per day—that adds up to more than 3,500 calories a week or one pound. Translation: this could be undermining your weight loss or actually causing you to gain weight.
While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to researchers at Yale, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.
