Adopting a new dietary approach can be a challenging endeavor, particularly when motivation wanes after the initial surge of New Year’s resolutions. However, a simple yet profound method known as the 80% trick, or Hara Hachi Bu, may offer a solution for those looking to lose weight, slow aging, and even reduce the risk of chronic diseases such as heart disease, cancer, and dementia.
This practice, which has gained attention due to its health benefits, encourages individuals to eat only one meal a day and stop when they are 80% full. It has long been practiced in regions known as “Blue Zones”—areas where people live longer, healthier lives, often reaching 100 years or more.
Dr. Deborah Lee from Dr Fox Pharmacy highlighted the method’s potential to reduce the overall intake of calories, which in turn decreases metabolic activity. “When you consume fewer calories, your metabolism slows down, leading to reduced oxidative stress,” Dr. Lee explained. Oxidative stress, a key factor in the development of chronic illnesses such as heart disease, diabetes, and dementia, can be minimized through mindful eating, which involves slowing down, chewing thoroughly, and listening to your body’s cues of satiety.
The science behind the 80% rule suggests that by eating less, we can combat the aging process. Dr. Lee emphasized that the reduction in oxidative stress could play a significant role in improving overall health.
One notable supporter of this method is Carol Vorderman, the former Countdown presenter, who has incorporated the 80% trick into her fitness routine. Vorderman, who combines this approach with regular gym sessions and a focus on raw foods like Brussels sprouts, advocates for a balanced lifestyle without obsessing over calorie counting. In her book Detox Your Life, she explains that her detox regimen is less about specific caloric intake and more about mindful food choices.
However, it is important to note that anyone considering the 80% trick should consult with a healthcare professional, particularly individuals with existing health conditions or those on medication. Adopting a new dietary practice may not be suitable for everyone, and professional guidance ensures it aligns with personal health needs.
In conclusion, the 80% trick provides a straightforward yet powerful approach to better health. With its potential to aid weight loss, improve aging, and protect against serious illnesses, this method, when applied mindfully, could offer long-term health benefits.
