Obesity is generally caused due to an imbalance
between calorie intake and calorie expenditure. Between 1980 and 2014 prevalence of obesity more
than doubled worldwide. According
to researchers, probiotics are supposed to help one lose weight and belly fat by 3–4% over a 6-week period. The gut bacteria regulate the overall metabolism and
can influence the calorie balance in our body. An imbalance in this gut
microbiota may affect fat metabolism and lead to weight gain. Probiotics are good
bacterial, taken either with food or with supplements. These probiotics have
important physiologic functions to maintain the healthy gut microbiota,
regulating food intake and appetite, eliminate fat, and maintain hormonal balance related to weight loss.
A healthy gut
is important for our overall well-being. Around 100 trillion
microorganisms a human body is believed to carry in the intestines and this is
more than ten times the total number of human cells. These
microorganisms or bacteria are collectively known as gut flora or gut
microbiome. Gut microorganisms evolved and
developed a symbiotic relationship with humans. Healthy gut microbiota is required
to maintain a healthy gut. They break down the undigested foods and provide
nutrients while stimulating epithelial cell differentiation and proliferation.
These bacteria regulate intestinal homeostasis by inducing antibody production
involved in the development of immune and thereby helping to fight off the bad
bacteria that can sometimes invade our intestinal system through contaminated
food.
Imbalances in
intestinal bacteria can lead to:
·
Obesity and metabolic diseases
·
Malnourishment
·
Inflammatory diseases, like Crohn’s disease
and Asthma
·
Depression and Mood disorders
·
Cardiovascular Problems
WHAT ARE PROBIOTICS?
The World
Health Organization defines probiotics as ‘live micro-organisms which, when
administered in adequate amounts, confer a health benefit on the host’.
Health benefits
credited to probiotics are mostly related to your digestive system. Some of
these digestive system benefits have either a direct or an indirect effect on
your weight.
Few health
benefits of probiotics are:
v
Helps in food digestion
v
Improves the immune system
v
Helps in improving mental health
v
Helps in preventing and reducing acne
IS IT REALLY NECESSARY TO TAKE PROBIOTICS?
When the balance between good and bad gut
bacteria is disturbed, significant health problems can occur. Imbalance in the gut
bacterial community is medically termed gut dysbiosis. Many different
things can negatively affect our gut flora.
Threats to
the gut microbiota include:
1.
Antibiotics - Antibiotics
(the opposite of probiotics) are used to fight bacterial infections. However,
they not only kill or inhibit the growth of harmful bacteria but also kill the
useful good bacteria. Long-term use of antibiotics can lead to serious health
problems.
2. Triclosan
– Triclosan is an antibacterial found in toothpaste, mouthwash, hand sanitizers, and soap products has a role to wipe out our gut flora significantly.
3. Diet - Processed
foods and diet low in fiber and high in unhealthy fats increases the levels of
inflammation that start to kill off the gut flora within our digestive system.
This is why probiotics consumption is required
to restore and rebuilt the bacterial balance of the gut.
HOW DO PROBIOTICS REALLY WORK?
Probiotics
are believed to cleaning up the digestive tract and making it function better,
thereby making your body burn off fat quickly and effortlessly.
1. Probiotics Help Expel Dietary Fat from the
Body
A study on the particular strain of probiotic, lactobacillus
gasseri, showed to have help in the expulsion of dietary fat through fecal fat excretion in
humans. According to researchers, Lactobacillus
gasseri suppresses dietary fat absorption in the small intestine, thereby
also inhibiting calories intake. Another research in Japan showed that milk fermented
with Lactobacillus gasseri can reduce
waist circumference, abdominal fat, BMI, as well as the dangerous visceral fat
that accumulates around the organs.
2. Probiotics Have Appetite Suppressant Effects
Leptin
is an appetite control hormone, which balances the levels of energy and body weight. Eating probiotic-rich foods can help to suppress appetite by increasing the level of leptin in your body. Probiotics actually
stimulated the release of leptin. Leptin is the satiety fullness hormone this actually helps you consume
fewer calories and prevent overeating while snacking between meals.
3. Probiotics Help Burn Fat
Probiotics can have a
very beneficial effect to lower fat deposition. Probiotics promote the production of
numerous proteins that can reduce the rate of fat deposition in the body. Even
if your diet was not perfect, you can reduce the fat stored in your body for
belly fat. Research using the strains lactobacillus
amylovorus and lactobacillus
fermentum and another using lactobacillus
rhamnosus has shown to boost your metabolism and burning more
calories and fat. Probiotics can help to burn two times as much visceral fat and
subcutaneous fat that can lower the risk of diabetes and heart conditions along
with achieving weight loss target.
4. Probiotics
Prevent Inflammation
Probiotics
also, prevent inflammation. Many people who suffer from chronic inflammation in
their gut can lead to an increase in fat deposition and a slower metabolism. However, probiotics having the ability to prevent inflammation in the stomach and
boost metabolism to burn fat faster.
5. Probiotics Reduce
Calorie Absorption
Studies had
shown taking probiotics with foods would reduce the absorption of calories in the body without hampering the absorption of nutrients. Probiotics even produce important nutrients such as vitamins B and K. To obtain the best result pair this with exercises for much faster
weight loss. The right amount of probiotics
in your body improves digestive efficiency along with the absorption of
nutrients more efficiently allowing you to eat less before you feel full yet
still obtaining all the minerals and vitamins your body needs.
THE BEST PROBIOTICS FOR WEIGHT LOSS
Many studies have
been conducted on probiotics, to find out their involvement that affects
different aspects of weight loss. Some strains of probiotics appear to have anti-obesity effects
and are quite effective in burning off the extra body fat, while others actually
seem to cause weight gain.
1. Lactobacillus gasseri
From the available
evidence, Lactobacillus gasseri
appears to be the best probiotic strain that can assist in weight loss in humans. In a Japanese
study on 30 healthy individuals, researchers prepared two different batches of
fermented milk. One batch contains the active milk with Lactobacillus gasseri, and the control milk without. Both milk
preparations were indistinguishable in taste and equivalent in energy, in
protein, fat, carbohydrates. Fecal samples collected at the beginning and end
of the trial showed that the Lactobacillus
gasseri group had an increased amount of fat excreted in their feces after two
weeks of consuming the milk. Whereas, after the same period, in the control group
no changes in fecal fat excretion were noticed. The Japanese control trial also found
that fermented milk with Lactobacillus
gasseri significantly reduced BMI,
waist circumference, abdominal fat, and the dangerous visceral fat that
accumulates around the organs.
2. Lactobacillus fermentum, Lactobacillus
amylovorus
Lactobacillus fermentum or Lactobacillus amylovorus are two
other strains of the Lactobacillus family can help you lose weight
and belly fat. According to one study,
participants who ate yogurt fermented
with Lactobacillus fermentum or Lactobacillus
amylovorus reduced body fat by 3–4% over a
6-week period.
3. Lactobaccilus rhamnosus
According to a study published in the
"British Journal of Nutrition" in April 2014, found that supplements
of another probiotic, Lactobaccilus
rhamnosus, when combined with a low-calorie diet appear to help obese women
lose both body weight and body fat. Over the two-year study period, the women
receiving the probiotic supplements lost about twice as much weight in compare
to women who followed the same diet without taking the supplements.
4. Bifidobacterium lactis
Bifidobacterium lactis appear to reduce fat mass, body weight, and weight
gain
5. Lactobacillus plantarum
Lactobacillus
plantarum,
may be more likely to cause weight loss.
According to a
meta-analysis of multiple studies, some Lactobacillus
strains, including ingluviei, acidophilus, and fermentum showed a tendency toward weight gain rather than loss,
both on human and animal subjects.
FERMENTED
FOODS HIGH IN PROBIOTICS:
If you do not
want to take the probiotic supplements, there are some foods you can eat on a
regular basis that will aid in keeping your digestive tract filled with these
beneficial bacteria. Do not forget that the key to getting the effects of these
foods is being consistent in eating them. Some that are rich in probiotics and
help to weight loss are given below. You can take it as individual
preparation or in combination.
Dairy
Products
1. Yogurts - Yogurt is one of the food sources rich in probiotic. Most
potent strains of lactobacillus and bifidobacteria are found in yogurt. Homemade
yogurt with naturally rich in those live cultures is always better than the
packed ones. People with lactose intolerance should avoid this.
2. Kefir - Kefir is a fermented milk drink, cultured from kefir
grains. Kefir grains contain around 30 strains of beneficial
bacteria. Some of the major probiotic bacteria
strain found in kefir products
include Lactobacillus
acidophilus, Bifidobacterium
bifidum, Lactobacillus
kefiranofaciens, Lactococcus
lactis. Kefir is actually a much more potent source probiotic than yogurt. Both yogurt
and kefir are made from fermented milk but kefir contains many
bacteria that aid lactose digestion. Kefir does not produce
symptoms of lactose intolerance because these bacteria already pre-digested the lactose in kefir. However, kefir has a broader range of nutrients than
does yogurt. Lactobacillus kefiri, and the carbohydrate kefiran, protect against harmful
bacteria.
Non-Dairy
Products
3. Miso - Miso is a traditional Japanese appetizer prepared from
fermented soy, rye, beans, barley, or rice. It contains a huge amount of lactobacillus acidophilus. Miso generally
used as a condiment.
4. Kimchi - Kimchi is a Korean fermented foods veggie side dish, made with
cabbage, radishes, and scallions. Korean researchers at Kyung Hee University found
that Lactobacillus brevis,
the culture strain found in kimchi suppressed the diet-induced increase in weight
gain by 28 percent.
5. Kombucha - Kombucha tea is prepared by
fermenting sweet black tea with a culture of yeasts and bacteria known as
Kombucha mushrooms. This probiotic beverage helps in boosting the immune system
of our body. It also provides energy, helps the body to stay fit and healthy.
It helps in losing weight too. However, care must be taken since this tea may
not suit everyone.
6. Sauerkraut - Sauerkraut is fermented shredded cabbage in brine, and it contains natural compounds that have potent belly fat slimming
properties. When unpasteurized, sauerkraut is rich in Lactobacillus
bacteria. It contains lactobacilli
plantarum, which aids in boosting the immune system and reduces the growth
of yeast in the body. Sauerkraut is one of the richest non-dairy sources of probiotic, even more so than yogurt.
7.
Fermented Green Olives - Fermented Green Olives contains live cultures of Lactobacillus
plantarum and Lactobacillus pentosus. L.
plantarum shows great potential shedding belly fat to a flat
stomach.
Switching
your probiotic supplement is a good idea. Different strains provide different
health benefits, even with strains of the same genus and species exhibiting
different effects. Probiotics can be dangerous for those with compromised immune systems.
Probiotics
may assist very well in weight loss, but only if you already live a very active
lifestyle. Of course, do not expect any miracles with probiotis only without a
nutritious diet and regular exercise.
