C4 really put the effort into making this programme well rounded and thoughtful, not holding back on the trickier topics that actually enable obesity. There's so much folk can learn from cultures beyond a person's individual cultural, media and lifestyle bubbles - councils and governments have a lot to learn too when it comes to making health more accessible.

They are taking action and being part of something encouraging others to take action, doth my cap & wishing the the very best.

"I've lost nearly a whole skinny person" 😂😂😂

To be honest Japan have got it bag on right. If we are to adopt the technological advancements that make our life easier but make us move less, e.g. cars, trains, buses, desk jobs, and eat more, e.g. shops with food readily available to us, then we need to put strict practices in place to counter balance these added conveniences to ensure we keep ourselves healthy and moving as nature intended humans do. If you are to sit at your desk all day, then a brief period of light exercise should be mandatory to prevent postural injuries and also combat the lack of movement. If we have food available to eat all day and night long, we should have our waists measured to hold us accountable to not over eat. Obesity has become the consequence of benefitting from convenience without enforcing any restrictions. As a nation we have become very lazy. The stress of modern life makes us feel like it's okay to reward ourselves all the time but the truth is we need more discipline and need to realise life is about struggle and suffering as much as it is about enjoyment. If we were out hunting and scavenging in the wild, we would sometimes go days walking miles without food. And our bodies are built to be able to deal with this. But today, if someone doesn't have breakfast we act like they are punishing themselves and starving themselves to death. Or if they run 5k we make passing comments like god, i don't know how they do it or why they put themselves through it. Even though in the wild we would naturally go longer than a morning without food and run further than 5k hunting, or running away from a predator over the course of the day. We have become very blind and detached from our natural way of living and very soft, weak and fragile. We need more discipline. You are not a victim, you are living a thing called life that comes with as much suffering as it does pleasure. If you are eating too much and not moving enough for short term pleasure then you are doing life wrong and will have to deal with the consequences of your choices, which will be obesity, disease, low self esteem and mental illness. Yes, enforce those hard rules on yourself that lead to a bit of short term suffering if you want the benefit of long term mental and physical health and resilience. Life is hard but the suffering is what makes the pleasure worth it.

Most of the things they said about Japan were not true. "Eating up to 80% full" is a stereotype of OKINAWA, not all of Japan and most Japanese don't use chopsticks for everything (They use spoons usually for fried rice, Japanese curry, etc and knives and forks for other types of food, etc). Even if they do use chopsticks, some people here (such as kids, working class people or workers on their lunch breaks) might shovel food into their mouths with chopsticks to eat their food quickly. Japan also had loads of junk food. Most convenience stores sell hot food, such as fried chicken, hash browns, fried chips, etc, and the readymeals/TV dinners (curry, pasta, chow mein, etc) can be cooked by the staff for you and are high in calories. Most packets of crisps over here are also "family size", as they're "meant" for groups (so you can't really buy regular sized packets). There are also a fair amount of overweight people living here too. Not all jobs measure your waist or do exercises either (none of mine do). We do get health checks by some employers though. Also, it's impolite to not finish all of your food in Japan. Some restaurants have signs telling people to not waste their food. I've never seen anyone in Japan leave food on their plates.

It's processed food, accessibility to an abundance of food, lack of movement. This has only became a problem post war.

Keep going guys. You’re doing great and can get there.

It's a mental health/addiction issue. There's no shame in seeking help for their issues and there's plenty of support just like drug and alcohol addiction

This is interesting. I hope they give the details at the end.

what cargo plane took them to japan?

Wow. That Japan segment was unbelievably exaggerated bordering on completely WRONG! The Japanese are taught to eat everything on their plate. They just don’t fill their plate to the brim. Throwing away rice is a total no go! The measuring the waist is part of a yearly health check. Not a daily thing!

What's the name of the series?

Genetics play a small role. It’s the lifestyle that pulls the trigger. I’m glad to know how they are trying to prevent the life threatening diseases. It may seem harsh but it’s needed for a good quality of life

start again monday

You don’t get this big unless you eat processed junk all day. Doing so you’ll constantly feel hungry because of the poor nutritional content of processed junk - which overall costs more than fresh ingredients - and thusly over eat. Once you become a little larger, exercise becomes harder, so you spiral down into gross obesity. To get out is a massive challenge….

Id actually love to live in Japan

Once again not addressing what works. Low carbs, intermittent fasting and walking.

Hiya, if anyone over here is trying to lose weight or had diabetes, I have just the thing for you. My dad has gone from 7 pils to 1 (diabetic). Also lost tons of weight. Whilst eating all the food he wants to eat. Life changing stuff. Drop me a message if interested.

The quality of interview questions on this show is dismal contributing to dumbing down society

How much food food did they have to eat to get that big in the first place? 😮

To be that big they are eating alot in the day over 6k calories

How are they tackling obesity, look at the state of them, if anything they've put on more weight!

Maybe they should walk there 🤷 if they only walked from Scotland to Cornwall they would be half the size

She ate all the hastags thinking they hashbrown

Its defo not rockett science

You won’t get “willpower” to loose weight by travelling to different places in the world..there is plenty of help available everywhere…..these people are getting paid to do the show…who wouldn’t jump at a free trip to another country to loose weight?

delusion at the highest level

If they walked a mile every day, they’d be a normal weight. It might take a year or two or maybe even three years but no need to diet or look at the scales, just move your body
