There are so many opinions on the best way to lose weight that it can sometimes be downright confusing. Fitness expert Eugene Pallisco understands why people don't know what plan to follow since, many times, the advice is contradictory from one plan to the next.

Luckily, many recent scientific studies have uncovered the inner workings of metabolism and how best to lose weight. If you want to lose weight, one of the most effective things you can do is follow the science.

Below is a discussion of the science of weight loss, including calorie deficits and effective strategies.

Start with Your Diet

There's much talk about how exercising is the key to losing weight. Even small changes in daily routines, such as avoiding the elevator and opting for the stairs, contribute considerably to weight loss.

And while exercise is a massive contributor to weight loss, it all starts with diet. That's because when you boil it down to the basics, you lose weight when you achieve a caloric deficit.

When you take in fewer calories than you expend, you lose weight. It's as simple as that.

This description is why so many people focus on exercise. They think that by expending more calories, they'll lose weight faster.

While exercise certainly will help you expend more calories, eating better has a much more significant impact than exercising. By making simple, smarter eating choices, you can have a much more immediate effect on your calorie deficits than by increasing your exercise.

Exercise for Metabolism

Exercise is essential for weight loss, even if it's not the first thing you should focus on.

In addition to increasing the calories your body expends, it also helps to build your metabolism, which results in your body burning calories more effectively and efficiently. Exercise can also repair metabolism that is "broken" or has been slowed over time by poor eating habits and a lack of exercise.

When starting a new exercise routine, it is essential to be consistent and regular. It doesn't have to be high-intensity. Something as simple as walking for an hour a few days a week at first is a great place to start.

Support a Healthy Brain

Brain health is often overlooked when it comes to weight loss. Yet, every aspect of weight loss comes down to how the brain functions, according to Eugene Pallisco.

Every decision you make affects your weight. Will you eat those potato chips or opt for something healthier? Will you exercise today or skip it and binge-watch a TV show?

You're more likely to make all-around healthier choices when you're in a good head space. This emphasizes the importance of being in an excellent mindset to lose weight.

Ironically, getting on a suitable wavelength is easier when you eat right and exercise. So, keep at it and remind yourself how much better you'll feel overall by following the science behind weight loss.
