Seasonal allergies have hit a fever pitch during this time of year.

Losing weight can also provide some benefits in the bedroom. A study from the Journal of Sex & Marital Therapy showed that women who lost weight significantly spiked their positive body image and increased their sexual activity. Dudes will see a difference between the sheets, too. Overweight men often have low testosterone levels, but a new study from Endocrine Society suggests that weight loss can increase testosterone levels by 50 percent. So go ahead, get it on.

You'll Sleep Well

If you're not sleeping well, putting some work in at the gym can help you get some essential shut-eye. A study from Johns Hopkins University showed that exercising at least 150 minutes a week can help treat sleep disorders like insomnia and obstructive sleep apnea. In overweight participants, frequent nasal blockages occurred during the night and led to unrestful sleep, but losing weight helped them get better quality zzzs.

Your Memory Improves

It turns out losing weight will also keep you sharp as a tack. According to research in Neurology, the cognitive abilities of overweight people decline significantly faster than those who are at a healthy weight or are losing weight. Crossword puzzles and board games might boost your noggin, but shedding some pounds can help you lower cortisol levels, which can affect memory.

Your Food Will Taste Better

If that green salad, or better yet, your favorite comfort food doesn't taste as delicious as you remembered, the number on the scale might be to blame. One of the most surprising reasons to lose weight is that being overweight actually decreases your sensitivity to taste and can lessen the number of taste buds you have, according to a study in PLoS Biology. Slimming down can help you truly savor your meals and enjoy the food in front of you.

You'll Save Money

According to a Health Affairs report, slim people spend thousands of dollars less on medical bills and health expenses than their overweight peers.

Like a well-timed cup of coffee, losing weight can serve as the energy boost you need to make it through everything from a long workday to a marathon. And since you're sleeping well too, you'll have more energy to power your day. Research from Harvard Health Publishing agrees. Simply put, when you weigh less, your body requires less energy to function.

You'll Have Clearer Skin

Whether you're a teenager or an adult struggling with acne, studies suggest that losing weight can contribute to less clogged pores and problem spots. Unlike fruits and vegetables with skin-loving nutrients, high-glycemic foods that pack sugar and fat are zit-causing culprits. So the healthier you eat, the more you'll glow from within.

You Can Relieve Joint Pain

Living with chronic joint pain makes it difficult to be active, but losing some pounds can help relieve pain and give you more freedom of movement. A study from Radiology reported that being overweight places extra pressure on your joints and cartilage, causing them to wear faster and more easily. People with more body fat typically see more inflammation in the joints, which also contributes to pain.

Your Partner Could Lose Weight, Too

Your weight loss can inspire friends, family or your partner to be more proactive with their health and adopt positive habits, too. Let's face it: Eating clean and working out is much easier with a swole mate. Studies have shown that if surround yourself with people who want to make the same healthy lifestyle changes, you're more likely to stick to them.

Your Metabolism Will Skyrocket

Your Heart Will Thank You

Following a nutritious diet and regular exercise routine can help completely reverse the effects of obesity and improve your overall health.
