Calories are a unit of measurement for the amount of energy in food and beverages.

We put energy into our bodies when we eat and drink. This energy will then be used in our daily activities, such as breathing, sleeping, and running.

To maintain a stable weight, we must balance the energy we put into our bodies with the energy we use through normal body functions and daily activities. Simply put, the more calories you put into your body, the more activities you need to do to burn them off, and vice versa.

General calories intake

Men on average need about 2500 kcal per day, while women need about 2000 kcal per day. However, as mentioned above, the amount of recommended nutrient intake varies from person to person based on their daily activities, occupation, frequency of exercise, lifestyle habits, and also body metabolism.

The more vigorously you engage in an activity, the more calories you will expend. Fast walking, for example, burns more calories than moderate walking. If you're gaining weight, it could be because you've been eating and drinking more calories than you've been burning. To lose weight, you must expend more energy than you consume; this can be accomplished by eating less or exercising more vigorously. Doing this consistently over time will get you to your desired weight.

When people try to lose weight, they tend to restrict their food intake and often do not enjoy their diet changes. A healthy diet should also be a sustainable diet, which means gradually but consistently reducing unhealthy food consumption, consuming more healthier food options, and being mindful of the amount of food consumed.

Calorie counter

Nowadays, there are various apps that can be used on a mobile phone to track not only your calorie intake but also your steps, exercise, and the energy that you burn. Using all these apps and gadgets is helpful in making sure that you are on track with your diet and exercise.

One of the apps developed by the Ministry of Health Malaysia that is compatible with the Malaysian variety of foods is My Nutri Diary 2.0. The app is helpful in monitoring your calorie intake and your weight progress. Often, when we use calorie tracking apps, it frustrates users that the app does not know how many calories a nasi lemak has (or any local food), but with my nutri diary, it covers a variety of Malaysian food options, which can be helpful for our daily food consumption.

Gap between unhealthy diet and body needs

While trying to lose, put on, or maintain weight, imbalanced consumption of foods may lead to the loss of some essential nutrients. Hence, to bridge the gap between the lack of nutrients in food and what the body needs, consumption of multivitamins and multiminerals is helpful.

Other conditions include denture problems, loss of appetite, a hectic lifestyle, and many more.

In this article we are going to focus solely on slimming products that people consume like functional foods, pills, beverages, not for external use like ointment, lotion, or other types of slimming products since different kind of product has different method on how they give effect to the body.

Slimming pills on the market is either from drug, or drug combination or from herbal supplement. As for drugs at the moment, in Malaysia we only use two types of drugs which is anti-obesity medicine (AOM) that act on gastrointestinal tracts (GIT) or better known as orlistat (brand name Xenical) and drugs which is used to suppress appetite or better known as Sibutramine or phentermine. The consumption of all these drugs must be prescribed and monitored by doctors.

There are certain criteria for doctors to consider in order to prescribed slimming pills such as when individual has BMI more than 30, but most importantly is when the individual have tried to loss weight like eat healthily and exercise. Once individual have achieved certain weight loss then the doctor can no longer prescribed the medication, which is why, the consumption of such drugs needs to be monitored by doctors only. Also, to note that there have been cases previously where the prescription of slimming drugs which harm individual health, the drug is called Fen-Phen, it was phenomenal back then, it was a combination from Phentermine and Fenfluramine, but Foods and Drugs Administration (FDA) already take it back from the market as it can harm human health specifically heart valve. When prescribing slimming drugs doctors will usually conduct full body examination and blood test from time to time thus whatever things that is not suitable for body may be detected early, unlike consuming slimming pills without prescription.

As for herbal supplement slimming pills, the ingredients can be from various ingredients, either plant-based ingredients or animal-based ingredient. Since it does not consider as drugs thus it is not put under the strict and effectiveness requirement that drugs are in.

In Malaysia, all these supplement products need to be notified to Ministry of Health (MOH) under the National Pharmaceutical Regulatory Agency (NPRA) for its safety. Once it is being notified, NPRA will provide the supplement products with notification number. Many product founders use this as their marketing strategy as to promote that their product is approved by MOH. However, products with notification number does not means that they are safe. It means that they are confident that their product is safe so that MOH can come and spot check anytime to make sure that their products is safe. Of course, before NPRA provide the product with the notification number they already go through the product ingredients and all that, but different batches of supplement are produce over the time, which can be different from the one sent for checking initially.

Among common ingredients that are in slimming pills supplement are chitosan (from shrimp shell), caffeine, bitter orange, green tea, beta gluten, carnitine, raspberry ketone, white kidney bean, yohimbe, guar gum, garcinia cambogia, fucoxanthin and many more. All these ingredients usually do not have conclusive study findings but rather mixing or promising study findings.

Which is why when it comes to supplement consumption it is very much suggested to go through below guideline from MOH:

1. Check the products that you are going to buy whether it is registered with the regulatory authority.
2. Some of the products (including herbal) may also cause adverse effects. Make sure your medical condition is not affected by it if you would like to try these products. Seek advice from healthcare practitioner before consuming it.
3. Read label carefully and do not take more than the listed dose.
4. These products are licensed as either over the counter (OTC), traditional, or functional food, therefore it is not ethical for the founder to make claim such as ‘stops from being fat’ or ‘speeds up metabolism’.
5. Avoid slimming products which promote rapid weight loss, promise quick result, suggest that you do not need to exercise or diet, fail to recommend dietary advice or worse encourage that you can still consume anything you want.

In conclusion, whether slimming pills work or not it is still depending on type of slimming pills itself whether it is considered as drugs (need doctor prescription) or herbal one which is over the counter pills. All in all, health experts agree that making lifestyle changes including following a healthy eating pattern, reducing calorie intake, and engage in physical activity is the basis for achieving long term weight loss. But since making lifestyle changes can be difficult to some people, even more nowadays that there are many temptations for unhealthy food around us, not to mention the processed food which is marketed as ready to eat or ready to cook food (microwaved) but contain high trans-fat. Thus, it is really suggested that if you are to consume any slimming pills, get advice from healthcare professionals and accompanied it with healthy eating habit and exercise.

Fasting has long been a part of many religious traditions, including the Jewish and Muslim holidays of Yom Kippur and Ramadan, respectively. As you read this, billions of Muslims around the world are participating in this act of faith, which involves fasting from dawn to dusk. While fasting for Ramadan is based on spiritual beliefs, many of us fast because we believe it benefits our health. However, what happens to our bodies when we fast? 

The primary source of energy for a person is glucose, which is obtained from carbohydrates such as grains, dairy products, fruits, certain vegetables, beans, and even sweets.

The glucose is stored in the liver and muscles and released into the bloodstream when the body requires it. This process, however, changes during fasting. The liver will deplete its glucose reserves after about 8 hours of fasting. At this point, the body enters a state known as glucogenesis, which marks the transition into fasting mode.

Glucogenesis has been shown in studies to increase the number of calories burned by the body. Without carbohydrates, the body burns its own calories. When there is no carbohydrate available, the body produces its own glucose, primarily from fat.

The body eventually runs out of these energy sources as well. Fasting mode then transitions into the more serious starvation mode. A person's metabolism slows down at this point, and their body begins to burn muscle tissue for energy. Although it is a well-known term in the dieting world, true starvation mode occurs only after several days or even weeks without food. So, unless other health conditions exist, it is generally safe to go without eating for a day after breaking their fast after 24 hours. (1)

“A detoxification process also occurs, because any toxins stored in the body’s fat are dissolved and removed from the body,” he adds, noting that after a few days of fasting, higher levels of endorphins – “feel-good hormones” are produced in the blood, which can have a positive impact on mental well-being. As mentioned previously, the study by Dr.Longo and colleagues suggests prolonged fasting may also be effective for regenerating immune cells. “When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged,” Dr.Longo explains. In their study, publish in the journal Cell Stem Cell, the team found that repeated cycles of 2 – 4 days without food over a 6-month period destroyed the old and damaged immune cells in mice and generate new ones.

Furthermore, the team discovered that cancer patients who fasted for three days prior to chemotherapy were protected against immune system damage caused by the treatment, which they attribute to immune cell regeneration. "The good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting," says Dr. Longo. "Now, if you start with a system that has been heavily damaged by chemotherapy or ageing, fasting cycles can literally generate a new immune system." (2)

Intermittent fasting, on the other hand, is associated with numerous health risks, according to the UK's National Health Service (NHS).

People who fast frequently become dehydrated, owing to their bodies' inability to obtain fluid from food. As a result, it is advised that Muslims consume plenty of water prior to fasting periods during Ramadan. Other people who follow fasting diets should stay hydrated during their fasting periods.

On the other hand, according to the UK’s National Health Service (NHS), there are numerous health risks associated with intermittent fasting.

Fasting can also cause heartburn; lack of food leads to a reduction in stomach acid, which digests food and destroys bacteria. But smelling food or even thinking about it during fasting periods can trigger the brain into telling the stomach to produce more acid, leading to heartburn.(2)

Finally, to sum up, moderation is the key. Know the precaution step to avoid the potential risk. A person must understand his or her current health condition before proceeding to any sort of diet plan.

To summarize, moderation is essential. Understand the precautionary measure to avoid the potential risk. Before beginning any diet plan, a person must first understand his or her current health situation.

Diarrhea is characterized by frequent soft or loose bowel movements (poop). Most children experience diarrhea from time to time. It usually does not last long and usually resolves on its own, but in children, the period when they have diarrhea is critical because they may be losing too much water, which can lead to other health problems.

Among the dehydration symptoms that parents and/or caregivers should look for in children who have diarrhea are:  

• Seems drowsy
• Breathes quickly
• Has few or no tears when they cry
• Has a soft spot on their head that sinks inwards (sunken fontanelle)
• Has a dry mouth
• Has dark yellow pee or has not had a pee in the last 6 hours (for baby) and 12 hours (for child)
• Hands and feet that appear cold and blotchy 

The World Health Organisation (WHO) defines probiotics as live microorganisms that, when administered in adequate amounts, confer health benefits on the host. It can be found in fermented foods (e.g., yoghurt, kefir, sauerkraut, tempeh, and kimchi), dietary supplements, and cosmetics.

Probiotics may contain a variety of microorganisms. The most common are Lactobacillus and Bifidobacterium. There are also other bacteria being used as probiotics such as Saccharomyces boulardii.

According to studies, different types of bacteria exert different effects on the human body. Therefore, choosing the right strains and types of probiotics is essential to address the said health concern.

Probiotics, Prebiotics, and Synbiotics.

Prebiotics are nondigestible food components that promote the growth of beneficial microorganisms. Probiotics are not the same thing. Prebiotics are commonly consumed by probiotics, which can stimulate their growth and activity. While synbiotics are typically products that combine probiotics and prebiotics. All in one supplement product, this combination allows bacteria (probiotics) to feed on prebiotics.

 Why probiotics are important?

Many studies on the benefits of consuming probiotics have recently emerged. Probiotics, according to the National Institutes of Health (NIH), may help your body maintain a healthy community of microorganisms or help your body's community of microorganisms return to a healthy state after being disturbed. It can also influence your body's immune response.

 Take away message

There is currently no recommendation for how much probiotics we should consume in our daily lives, but because it has so many benefits, many people have begun to consume probiotics on a daily basis. If you rarely consume probiotic-rich foods like the ones mentioned above, probiotic supplements can be used as an alternative.

Other than bacteria, the body contains fungi, parasites, and viruses. All of these "bugs" coexist peacefully and naturally in a healthy person, with the greatest number found in the intestines. Scientists refer to all these coexisting "bugs" in our bodies as the microbiome. 

The microbiome plays a key role in promoting the smooth daily operation of the human body. It consists of both helpful and potentially harmful microbes. The disturbance in the balance between the helpful and harmful microbes may arise due to infectious illnesses, certain diets, prolonged use of antibiotics or other bacteria-destroying medications, which can lead to the body becoming more susceptible to diseases. 

Scientists believe that probiotics are most effective at both ends of the age spectrum, that is, children and the elderly, during stress, after antibiotic consumption, and so on. Probiotics influence the bacteria colonization process, which can lead to a faster restoration of a healthy microbiome and a lower risk of illness. 

Probiotics also help to maintain health by influencing the body's immune response. Microbiota aid in the stimulation of the immune system in the body; for example, a healthy microbiota will protect the body from pathogenic organisms that enter the body, such as through the consumption of contaminated food and beverages.

A variety of bacteria families are found in the human gut, including Prevotella, Ruminoccoides, Bacteroides, Lactobacillus, Clostridium, and Firmicutes. These microbes in the gut prevent the overgrowth of harmful bacteria by competing for nutrients and attachment sites on the mucous membrane of the gut, which in turn provides immune activity to the body. 

In a nutshell, while there are numerous additional benefits to consuming probiotics, such as improved skin health, scientists are still trying to figure out how probiotics can help with other health conditions. However, large-scale studies, such as the Human Genome Project, show promising results on the health benefits of probiotics.
