The Most Effective Methods To Lose Weight, According To Science


Controlling your own weight can be difficult. There are many reasons why an increase may be occurring, and it is often difficult to identify the exact cause and act on it.

However, science has some ‘recipes’ that can help us achieve this reduction as easily and effectively as possible. Here we present some methods supported by scientific evidence to achieve significant weight loss.

However, it must be clarified that weight loss should only be attempted when there is overweight that entails health risks, and never for aesthetic reasons . Being overweight, especially if it leads to obesity (BMI over 30), can lead to an increased risk of serious disorders such as diabetes, hypertension or cardiovascular diseases, body dissatisfaction (marked by excessive concern about weight and physical appearance) and often fueled by cultural factors, it can lead to eating disorders, which in turn put the physical and mental health of the patient at serious risk.

  1. Intermittent fasting
    Intermittent fasting consists of alternating periods in which you eat normally with other short fasts . It is a method whose effectiveness in achieving weight loss in overweight people has been attested by various studies, such as this one published in the US National Library of Medicine .

There are several variations of intermittent fasting . One of them, the most popular, is the one that alternates a fasting day with a normal feeding day. There is also a modification (described in an article in the Journal of Diabetes & Metabolic Disorders ) that consists of alternating days in which the normal amount is eaten with days in which 25 or 30% of that amount is eaten.

Other versions are the ‘5: 2 diet’ (eating normally five days and restricting calories to between 500 and 600 two non-consecutive days in each week) or the ’16/8 diet’, which, as reflected in research published in the Nutrition and Healthy Aging medium , consists of eating only within an 8-hour interval during the day (for example, from 12:00 to 20:00 pm).

  1. Control exercise and diet
    Another possibility that has shown positive results in this regard is the regular control of diet and exercise performed , using this information to adapt calorie intake to the exercise performed in real time, according to a study published in the Journal of Medical Internet Research .

This can be done using, for example, mobile applications. There are several studies, such as one published in Plos One , that have found that people who monitor these two parameters have an easier time losing weight than those who do not.

  1. Mindful eating
    The practice of mindful eating consists of paying a special level of attention to our diet ; Instead of, as is often the case due to the stress and activity of contemporary urban life, quickly eat the first thing we have on hand.

The idea is to eat sitting down, avoiding distractions, actively enjoying food, slowly , and paying attention to the quality of the food we choose.

As evidenced by research from the University of California, those who adopt this method not only tend to eat a healthier diet , but by eating more slowly they give the brain time to recognize the feeling of fullness, so they have a lower tendency to overeat.

  1. Eat protein with breakfast
    Research published in the International Journal of Obesity has concluded that proteins reduce the presence in the body of hormones responsible for regulating hunger for several hours, which leads to people who eat them for breakfast have a lower tendency to Eat excessively.
  2. Minimize your intake of sugar and refined carbohydrates
    As Medical News Today reports , the consumption of refined carbohydrates and sugars has been shown to stimulate insulin production , which in turn promotes the accumulation of fat in adipose tissue. Therefore, minimizing the consumption of these components is related to lower rates of overweight and obesity; In addition, it has other positive effects on the body, since it also reduces the risk of cardiovascular accidents.
  3. Increase your fiber intake
    Fiber, which is part of many vegetables, is essentially a carbohydrate that the small intestine cannot assimilate, so it does not provide calories to the body. Instead, it provides a feeling of fullness , thus helping you avoid overeating.
  4. Take care of the intestinal flora
    In recent times, there are several investigations that have focused on the importance of bacterial flora in weight control. Bacterial flora is the name given to the billions of bacteria that symbiotically inhabit our intestines, and that fulfill essential functions in digestion.

Thus, for example, research published in the Karger medium found that having these bacteria in the right amounts and proportions maximizes the use of energy from food, which in turn reduces the body’s tendency to store fat.

Regular consumption of probiotic foods , such as fermented foods, and prebiotics , including vegetables such as onion, banana or avocado, helps to maintain a better balance in the intestinal flora.

  1. Improve the quality and quantity of sleep
    Insufficient or poor quality sleep is clearly related to higher rates of obesity , since it slows down the process by which the body takes advantage of the caloric intake , leading to the accumulation of energy not used in the form of fat; likewise, it affects the regulation of hormones related to appetite and satiety.
  2. Reduce stress levels
    Stress promotes the production of hormones such as cortisol, which when kept for long periods in the bloodstream stimulates the appetite, leading many people to overeat .

A study in the Journal of Mollecular Biochemistry concluded that better stress management over a period of just 8 weeks already causes significant reductions in the body mass index of obese people.

Some techniques that have been shown to be effective in reducing stress levels include sports such as yoga, Tai Chi, and some martial arts, breathing, relaxation, and meditation techniques, and outdoor activities such as hiking.
