How to lose weight naturally and fast
While there are endless diets, supplements, and meal replacement plans claiming to ensure rapid weight loss, most lack any scientific evidence. There are, however, some strategies backed by science that do have an impact on weight management. These strategies include exercising, keeping track of calorie intake, intermittent fasting, and reducing the number of carbohydrates in the diet.
In this article, we consider nine effective methods of weight loss.
Methods of weight loss that scientific research supports include the following:
1. Trying intermittent
fasting
Intermittent
fasting (IF) is a pattern of eating that involves regular short-term fasts and
consuming meals within a shorter time period during the day. Several
studiesTrusted Source have indicated that short-term intermittent
fasting, which is up to 24 weeks in duration, leads to weight loss in
overweight individuals.
The most common intermittent fasting methods include the following:
- Alternate day fastingTrusted Source (ADF): Fast every
other day and eat normally on non-fasting days. The modified versionTrusted Source involves eating
just 25–30 percent of the body’s energy needs on fasting days.
- The 5:2 Diet: Fast on 2 out
of every 7 days. On fasting days eat 500–600 calories.
- The 16/8 method: Fast for 16
hours and eat only during an 8-hour window. For most people, the 8-hour
window would be around noon to 8 p.m. A study on this method found that
eating during a restricted period resulted in the participants consuming
fewer calories and losing weight.
It is best
to adopt a healthy eating patternTrusted Source on non-fasting
days and to avoid over-eating.
2. Tracking your
diet and exercise
If someone wants to lose weight, they should be aware of everything that they eat and drink each day. The most effective way to do this is to log every item that they consume, in either a journal or an online food tracker.
Researchers estimated in 2017 that there would be 3.7 billion health app downloads by the end of the year. Of these, apps for diet, physical activity, and weight loss were among the most popular. This is not without reason, as tracking physical activity and weight loss progress on-the-go can be an effective way of managing weight Trusted Source.
One study Trusted Source found that consistent tracking of
physical activity helped with weight loss. Meanwhile, a review
study Trusted Source found a positive correlation between weight loss
and the frequency of monitoring food intake and exercise. Even a device as
simple as a pedometer can be a useful weight-loss tool.
3. Eating
mindfully
Mindful eating is a practice where people pay attention to how and where they eat food. This practice can enable people to enjoy the food they eat and maintain a healthy weight Trusted Source.
As most
people lead busy lives, they often tend to eat quickly on the run, in the car,
working at their desks, and watching TV. As a result, many people are barely
aware of the food they are eating.
Techniques for
mindful eating include:
- Sitting down to eat, preferably at a
table: Pay
attention to the food and enjoy the experience.
- Avoiding distractions while eating: Do not turn
on the TV, or a laptop or phone.
- Eating slowly: Take time to
chew and savor the food. This technique helps with weight loss, as it
gives a person’s brain enough time to recognize the signals that they are
full, which can help to prevent over-eating.
- Making considered food choices: Choose foods
that are full of nourishing nutrients and those that will satisfy for
hours rather than minutes.
4. Eating protein
for breakfast
Protein can regulate appetite hormones to help people feel full. This is mostly due to a decrease in the hunger hormone ghrelin and a rise in the satiety hormones peptide YY, GLP-1, and cholecystokininTrusted Source.
ResearchTrusted Source on young adults has also demonstrated that the hormonal effects of eating a high-protein breakfast can last for several hours.
Good choices
for a high-protein breakfast include eggs, oats, nut and seed butters, quinoa porridge, sardines, and chia
seed pudding.
5. Cutting back
on sugar and refined carbohydrates
The Western diet is increasingly high in added sugars, and this has definite links to obesityTrusted Source, even when the sugar occurs in beveragesTrusted Source rather than food.
Refined
carbohydrates are heavily processed foods that no longer contain fiber and
other nutrients. These include white rice, bread, and pasta.
These foods are quick to digest, and they convert to glucose rapidly. Excess glucose enters the blood and provokes the hormone insulin, which promotes fat storage in the adipose tissue. This contributes to weight gain.
Where
possible, people should swap processed and sugary foods for more healthful
options. Good food swaps include:
- whole-grain
rice, bread, and pasta instead of the white versions
- fruit, nuts,
and seeds instead of high-sugar snacks
- herb teas and
fruit-infused water instead of high-sugar sodas
- smoothies with
water or milk instead of fruit juice
6. Eating plenty
of fiber
Dietary
fiber describes plant-based carbohydrates that it is not possible to digest in
the small intestine, unlike sugar and starch. Including plenty of fiber in the
diet can increase the feeling of fullness, potentially leading to weight loss.
Fiber-rich foods
include:
- whole-grain
breakfast cereals, whole-wheat pasta, whole-grain bread, oats, barley, and
rye
- fruit and
vegetables
- peas, beans,
and pulses
- nuts and seeds
7. Balancing gut
bacteria
One emerging
area of research is focusing on the role of bacteria in the gut on weight
management.
The human
gut hosts a vast number and variety of microorganisms, including around 37
trillion bacteriaTrusted Source. Every individual has different varieties
and amounts of bacteria in their gut. Some types can increase the amount of
energy that the person harvests
from food, leading to fat deposition and weight gain.
Some foods can
increase the number of good bacteria in the gut, including:
- A wide variety of plants: Increasing the number of fruits, vegetables, and grains in the diet will result in an increased fiber uptake and a more diverse set of gut bacteria. People should try to ensure that vegetables and other plant-based foods comprise 75 percent of their meal.
- Fermented foods: These enhance the function of good bacteria while inhibiting the growth of bad bacteria. Sauerkraut, kimchi, kefir, yogurt, tempeh, and miso all contain good amounts of probiotics, which help to increase good bacteria. Researchers have studied kimchi widely, and study results suggest that it has anti-obesity effects. Similarly, studies have shown that kefir may help to promote weight loss in overweight women.
- Prebiotic foods: These
stimulate the growth and activity of some of the good bacteria that
aid weight control. Prebiotic fiber occurs in many fruits
and vegetables, especially chicory root, artichoke, onion, garlic, asparagus,
leeks, banana, and avocado. It
is also in grains, such as oats and barley.
8. Getting a good
night’s sleep
Numerous studies have shown that getting less than 5–6 hours of sleep per night is associated with increased incidence of obesityTrusted Source. There are several reasons behind this.
Research
suggestsTrusted Source that insufficient or poor-quality sleep slows
down the process in which the body converts calories to energy, called
metabolism. When metabolism is less effective, the body may store unused energy
as fat. In addition, poor sleep can increase the production of insulin
and cortisolTrusted Source, which also prompt fat storage.
How long
someone sleeps also affects the regulation of the appetite-controlling hormones
leptin and ghrelin. Leptin sends signals of fullness to the brain.
9. Managing your
stress levels
Stress triggers the
release of hormones such as adrenaline and cortisol, which initially decrease
the appetite as part of the body’s fight or flight response.
However,
when people are under constant stress, cortisol can remain in the bloodstream
for longer, which will increase
their appetiteTrusted Source and potentially lead to them eating more.
Cortisol
signals the need to replenish the body’s nutritional stores from the preferred
source of fuel, which is carbohydrate. Insulin then transports the sugar from
carbohydrates from the blood to the muscles and brain. If the individual does
not use this sugar in fight or flight, the body will store it as fat.
Researchers
foundTrusted Source that implementing an 8-week stress-management
intervention program resulted in significant reduction in the body mass index (BMI) of children and adolescents who are overweight or
have obesity.
Some methods of
managing stress include:
- yoga, meditation, or tai chi
- breathing and
relaxation techniques
- spending some
time outdoors, for example walking or gardening
Conclusion
It is
important to remember that there are no quick fixes when it comes to weight
loss. The best way to reach and maintain a healthy weight is to eat a
nutritious, balanced diet.
