What You'll Learn

Japan's first over-the-counter anti-obesity drug
Japan has seen a rise in obesity-related health problems, with a particular increase in weight-related type 2 diabetes and cardiovascular disease. In February 2023, Japan approved its first over-the-counter anti-obesity drug, orlistat, also known by the brand name Alli. This medication is designed to reduce the absorption of fat in the intestines and is intended for overweight people aged 18 or older with a waist circumference of 85 centimetres for men and 90 centimetres for women. It is recommended that the drug be combined with physical activity and a low-calorie diet for optimal results.
Alli has been available in more than 70 countries since its approval in the United States in 2007 and is sold by Britain's GSK plc in Europe and the United States. Taisho Pharmaceutical secured the rights to develop and sell the drug in Japan in 2009 and will be responsible for its sales. The drug will be available at drugstores through pharmacists and does not require a prescription.
The approval of orlistat as an over-the-counter medication in Japan is significant as it expands the options for tackling obesity in the country. Previously, the only over-the-counter option available was traditional Chinese herbal medicine, which lacked clinical support. It is important to note that anti-obesity drugs, including orlistat, work best when combined with lifestyle changes, such as a balanced diet and regular exercise.
While Japan has a relatively low proportion of clinically obese individuals compared to the United States, the availability of clinically proven anti-obesity medications is a positive step towards addressing obesity-related health issues. However, it is worth noting that there is a growing trend of products marketed as dietary supplements or conventional foods with hidden drugs and chemicals in Japan. Consumers are advised to exercise caution when purchasing such products, as they may contain harmful or undeclared ingredients.

Popularity of supplements for weight loss
Weight loss supplements are a popular category of products in Japan, with a variety of options available at local drugstores. While the effectiveness of these supplements may vary across different body types, they are often clinically certified by doctors and are considered a safe option to try.
Some popular weight loss supplements in Japan include Fancl Calolimit, which works by blocking the digestion of sugar, fats, and carbohydrates, and helps suppress blood sugar levels. It is made from natural ingredients, including mulberry leaf amino sugar, chitosan, and tea flower saponin. Another supplement, DHC Diet Power, contains 10 popular ingredients formulated to target fat loss. It is recommended to be taken multiple times a day before meals, in combination with exercises and diets. FUJIFILM Metabarrier Premium EX is also a well-known supplement that helps manage blood glucose levels, weight gain, and intestinal microflora. It contains isoflavones derived from Kuzunohana flowers, which aid in reducing weight gain.
However, it is important to exercise caution when purchasing weight loss supplements, as some products may contain hidden drugs or chemicals. For example, the Food and Drug Administration (FDA) issued a warning against "Japan Rapid Weight Loss Diet Pills Green" due to the presence of undeclared phenolphthalein, a suspected cancer-causing agent.
While supplements offer a convenient approach to weight loss, some individuals prefer alternative methods such as dietary changes and exercise. Intermittent fasting, calorie restriction, and increasing protein intake with foods like tofu are some strategies mentioned by individuals seeking weight loss in Japan. Additionally, activities like rucking (walking with a weighted backpack) and sports such as bouldering and soccer are suggested as enjoyable ways to burn calories and improve overall health.

Safety concerns over diet pills
Diet pills are a type of weight-loss medication intended to suppress appetite and make individuals feel full faster, thereby reducing calorie intake and leading to weight loss. While they may be effective in aiding weight loss, safety concerns have been raised about their use.
One significant concern is the presence of hidden or undisclosed ingredients in diet pills. In 2012, the Food and Drug Administration (FDA) advised consumers against purchasing "Japan Rapid Weight Loss Diet Pills Green" due to the detection of undeclared phenolphthalein. Phenolphthalein is a suspected carcinogen and genotoxic agent that can damage or mutate DNA. This incident highlights the potential risks associated with unregulated or improperly labelled diet pills.
Diet pills have also been associated with various adverse health effects. For example, pills containing DNP have been linked to several deaths and can cause long-term side effects such as peeling skin and heart damage. Additionally, some diet pills may interfere with the effectiveness of other medications, such as cancer treatments. The use of anabolic steroids in dietary supplements has been linked to liver injury, testicular disorders, and infertility, particularly in young men.
The safety of diet pills is further brought into question by their potential to cause dependency and harm mental health. While they may suppress appetite and aid weight loss in the short term, they do not address the underlying behavioural and psychological factors contributing to weight gain. As a result, individuals may become reliant on diet pills and struggle with weight management without them, potentially leading to a cycle of dependency and negative body image issues.
Furthermore, the unregulated nature of the diet pill industry exacerbates safety concerns. Many diet pills are marketed as herbal or natural products, exempting them from rigorous regulatory scrutiny. This lack of regulation allows manufacturers to include potentially harmful ingredients without proper safety testing or disclosure, putting consumers at risk.
In conclusion, while diet pills may offer a tempting solution to weight loss, they come with significant safety concerns. The presence of undisclosed ingredients, adverse health effects, potential interference with other medications, and the risk of dependency and mental health issues highlight the importance of approaching diet pills with caution. Proper regulation and comprehensive safety testing are necessary to protect consumers from potential harm.

Lifestyle changes for weight loss
Diet pills are a popular concept worldwide, and Japan is no exception. However, it is important to exercise caution when considering such products, as many are not properly regulated and may contain hidden harmful ingredients. The US Food and Drug Administration (FDA) has specifically warned against the use of "Japan Rapid Weight Loss Diet Pills Green", which has been found to contain undeclared phenolphthalein, a suspected carcinogen.
Instead of relying on potentially dangerous supplements, it is advisable to focus on lifestyle changes to achieve safe and sustainable weight loss. Here are some instructive tips for effective weight loss through lifestyle modifications:
Healthy Eating Patterns
Adopting healthy eating habits is crucial for weight loss. Focus on consuming a balanced diet rich in fruits and vegetables, aiming for at least five portions per day. Cut down on sugary foods and drinks, opting for healthier alternatives like water flavoured with lemon or lime. Read food labels and choose products with more green colour coding, indicating they are generally healthier options.
Regular Physical Activity
Increasing your physical activity is essential for weight loss and maintaining a healthy weight. Aim for at least 150 minutes of moderate-intensity exercise per week, which can be broken down into shorter sessions. Walking is a great, simple, and increasingly popular way to improve your health and lose weight. You can also try instructor-led workouts like dance or yoga from the comfort of your home.
Stress Management and Sleep
Getting enough sleep and managing stress are vital components of a healthy lifestyle. Stress can impact your weight, so finding healthy coping mechanisms is essential. Additionally, adequate sleep helps regulate hormones that control appetite, so aim for a consistent sleep schedule.
Gradual Weight Loss
Remember that safe weight loss takes time. People who lose weight gradually, about 1 to 2 pounds a week, are more likely to keep the weight off in the long term. Avoid fad diets or extreme measures that promise quick weight loss, as these are often unhealthy and unsustainable.
Support and Motivation
Share your weight loss plan with someone you trust. They can provide motivation and support when you need it and help keep you accountable. You can also consider joining a weight loss support group or seeking professional guidance from a healthcare provider or dietician.
Making these lifestyle changes can be challenging, but they are essential for achieving safe and sustainable weight loss. Remember to focus on your reasons for wanting to lose weight, and track your progress to stay motivated.

Natural products for weight loss
Diet pills are a popular go-to for people looking for quick weight loss solutions. However, many of these products are loaded with caffeine and may have hidden drugs and chemicals that can be harmful. In 2012, the Food and Drug Administration (FDA) advised consumers not to purchase or use "Japan Rapid Weight Loss Diet Pills Green" as they were found to contain phenolphthalein, a suspected cancer-causing agent.
- Catechins: Catechins are a group of polyphenolic compounds found in tea, particularly green tea, which contains about 30% catechins in its dry tea leaves. Ingesting high doses of catechins results in the loss of body and adipose tissue weights and the regulation of lipid metabolism. Green tea and its extracts have been shown to increase energy expenditure and fat oxidation in both animals and humans.
- Capsaicin: Found in cayenne pepper, capsaicin provides numerous health benefits. Research shows that capsaicin can slightly boost metabolism, increasing the number of calories burned throughout the day. However, one 2016 study suggested that the reduction in hunger caused by capsaicin may be more a result of gastrointestinal distress than increased hormones that influence feelings of fullness.
- Gymnema sylvestre: This herb is often used to help reduce blood sugar levels, but it may also aid weight loss. It contains gymnemic acid, which can help reduce the perceived sweetness of foods and ward off sugar cravings.
- Bitter orange: Makers of weight-loss products switched to bitter orange after the FDA banned products containing ephedra. However, it is unclear if bitter orange is safer. Natural Medicines states that it is "possibly unsafe" when taken by mouth as a supplement, and there is insufficient evidence to determine if it works for weight loss. Some studies show that bitter orange supplements can raise blood pressure and heart rate and may have dangerous side effects when combined with other stimulants like caffeine.
- Chromium: A review of 24 studies found that there are no significant benefits to taking chromium for weight loss. Natural Medicines states that chromium is "possibly ineffective" for weight loss, and higher doses can cause kidney damage.
- Chitosan: Chitosan is generally considered safe and typically causes no side effects, although some people may experience an upset stomach or constipation. However, the National Center for Complementary and Integrative Health states that it has not been shown to be effective for weight loss.
While these natural products may offer potential weight loss benefits, it is important to note that diet and lifestyle changes remain the cornerstone of therapy for obesity. Fasting, calorie restriction, and exercise are scientifically proven methods for weight loss and are recommended by medical professionals.
