The Science of Weight Loss: What You Need to Know

Weight loss is perceived as a complicated process. Many individuals across numerous social media platforms discuss the concept of losing unwanted body fat. The advice surrounding weight loss found on the internet is endless and may often seem contradictory. It may seem impossible to discard that undesired weight while switching between one fad diet, program, or product to the next. In all honesty, you should not have to follow one specific diet or spend much extra money to lose body fat. Weight loss can be achieved with the following three factors.


1) Physical Activity

Physical activity is not all about buying a gym membership or committing time to a long exercise routine. Instead, physical activity simply refers to the act of moving your body around. Any form of movement works to rid yourself of body fat. The most convenient and least taxing form of physical activity is walking. The next best would have to be swimming. One fun form of physical activity is dancing. Put simply, the best form of physical activity is the form of movement you enjoy doing best. You should not choose to run, skate, or play a sport if you dread doing so. If you often find yourself sitting when instead you could be standing, stand for a change. If you can pace the room, then pace the room. The more you move, the more your body requires energy. The more energy your body needs, the more calories it utilizes. The more calories used, the more body fat is lost.


2) Calorie Deficit

A Calorie deficit is the act of someone eating fewer calories than their body requires. For example, let us say that the average person needs 2,000 calories daily. For that individual to lose about one pound (0.45 kg) per week of body fat, they would have to consume 1,500 calories daily instead of 2,000 calories. That is the case, as one pound (0.45 kg) of body fat equals about 3,500 calories. Divide 3,500 calories by seven days, and this equals 500 calories. Once 500 calories are subtracted from the 2,000-calorie daily requirement, an average individual would have 1,500 calories allotted daily to successfully lose a single pound of body fat in one week. In extreme cases, someone could increase their daily calorie deficit to 1,000 calories or more, but this approach is not sustainable and is discouraged due to its adverse health effects.

To lose weight, you must consistently eat fewer calories than your body needs. The key word is "consistently." All elements of losing body fat depend on consistency. The best practice would be to log the foods you eat into an app like MyFitnessPal, Lifesum, or Noom. Additionally, begin to cut out fast foods and junk from your diet. It is best to slowly eliminate the junk food you crave, as it helps to prevent relapse. Choose to eat foods lower in calories that have higher protein, lower fat (reduced fat or fat-free), higher fiber, and lower refined sugar (sugar-free). Explore more-nutritious alternatives for junk food when you can. The biggest culprit that leads to weight gain is liquid calories (examples: whole milk, fruit juice, soda, cooking oils).


3) Sleep

Sleep may not seem like it is an essential factor for weight loss, but surprisingly it is. Sleep acts as the body's reset. When you sleep, your body is still undergoing numerous key processes for longevity and proper day-to-day function. Without adequate sleep, your body does not have time to reset itself. This process can be compared to the reset on an electronic device. For a software update to function, the electronic device must be reset. When you sleep, your body is still updating and polishing all the biochemical processes occurring within you, one being metabolism. Like an un-updated device, your metabolism may function less efficiently and could begin to stall. Health experts advise the average person to sleep approximately eight hours per night.

Consider all three of these factors to optimize weight loss. As mentioned earlier, weight loss depends heavily on consistency. Be determined to apply healthier habits now, and you may thank yourself in the long term. I wish you the best of luck with your weight loss journey.
