This was by far a better option than watching New Zealand's mundane Friday night TV offerings. Thank you for continuing to add to the education of people of all ages. My first experience of the RIGB was watching the first Christmas Lectures by Eric Laithwaite, unfortunately on the "missing" list, and I still find myself looking forward to the next Christmas Lectures despite being what nobody would describe as a "young person" at 67 years old.

That means a lot to us, thank you. And you're in good company when enjoying the Christmas Lectures. We see it as a family show that can be enjoyed by all people of all ages.

Good questions, and even better answers! I had some issues that I think Giles should've addressed, but at least mentioned, and he answered most of them here.

Thanks you for a great lecture and Q&A.

Humans are the only beings that leverage on knowledge to make reasonal decisions against instincts for our benefits and goals. Thanks for the video. More can benefit from the knowledge. What we know, we can use to our advantage.

Giles is fantastic, but the questions were also great. Very informative Q&A.

Giles - One of the best!

Thanks to the Royal institution and Giles. An eye opening talk.

Thank you Giles!

Very informative and may do much to reduce tendencies to shame obese people. I bought the book on Audible while watching.

There needs to be similar study on what motivates people to exercise or not. The other half of the scales.

Don’t have the technology really to understand motivations quite yet. At least that specifically. Can do mri and see what lights up, but understanding human motivations is beyond our capabilities right now. But clearly, humans value comfort over health. The last 50 years have demonstrated that quite well.

There has been some work in this area. Social exercise seems to be quite motivating for many people, e.g. team sports. In part you feel more obligated because others are depending on you and expecting you to show up, it's also probably more fun. Another big part is habit, if people can do it long enough for it to become habitual, then they are much more likely to continue beyond that. Exercise is unfortunately much less effective than diet when it comes to weight loss, so I would hesitate to call it the other half in that respect. In terms of overall health though, I wouldn't be surprised if exercise is potentially even more important than weight.

@@markislivingdeliberately Really? I'm not terribly convinced of that. After all, running for one's health (jogging) was a bit of a novel concept 50 years ago. I think we have become far more aware over the last 50 years that there even was some sort of health/comfort dichotomy...though I think that is a misnomer. As someone on the heavier side myself, I can tell you that it is not more comfortable, not socially and not physically, so it's sort of weird to refer to not exercising as the comfortable choice. There can also be a bit of a vicious cycle, you don't want to go running because you're heavy and it's embarrassing, you don't, and then you get heavier, so it would be even more embarrassing, etc... I think our food decisions are largely overshadowed by the moment unless we put significant effort into planning and sticking to a diet. You go to work thinking, "I'll just have a sandwich for lunch today." You have a bit of a rough morning, an unpleasant meeting and you're not making as much progress on your project as you should, lunch rolls around, you go to the cafeteria, and now you're really craving the buffet. It smells delicious and you don't want to get back to work after the 5 minutes eating a sandwich would take, you want to take 20 minutes to reset before diving back in. So ok, you slipped, but you tell yourself you'll have less at dinner, or you'll only have the sandwich for lunch tomorrow... When you're less stressed you're more likely to make better health decisions. Say you go in, you're making good progress in your work, finding some exciting results, you hardly even want to take the time to eat lunch, you do only eat the sandwich at your desk while you continue coding so you can get the next part running before you leave. Once you submit those jobs to the cluster, there isn't too much to do until they are done the next day so you leave a little early and go play basketball with a light mind. That is my anecdotal (unreliable) take on the matter. Sure, we can't fully see motivation in the brain, but there is nonetheless an extensive body of literature investigating motivation with many clever experiments. Do read them with caution though, as there are many papers that have not been reproducible.

I would love to be able to send off to determine if I have any of these genetic factors. Then again, I'd like to be able to have a fMRI going throughout my day to see how my brain works while I'm dealing with people on the phones. It'd be neat if we could know more about ourselves.

I did 21 day fast with only water/coffee/tea and salt/magnesium/potassium and lemon juice in water occasionaly but nowhere around 21 day i was much hungry. I was just missing something to chew, something to have in my mouth. Many ppl can go 40+days without food. Salt helps a lot, one time daily some big crystal of salt. I was cold all the time (big sign in slowed/sparing metabolism), so wearing more clothes helped greatly, but never meassured my temperature, must try next time :)

Nobody ever says ‘hey it’s Friday night, let’s go crab a kale salad and some iced water!” Works every time.

I feel the food industries play a huge role, you will eat what's available when you are hungry and Japanese tend to favor whole foods culturally instead of processed foods. Capitalism also has some parts to play in tweaking foods to be as addictive as they can within regulations to maximise profits which isn't as powerful in some Asian countries. Individualism (western) vs collectivism (eastern) also affect the marketing and regulations of foods and healthcare, the collective "good" of the population in a collectivistic country will culturally steer the mentality in some manner.

In the word, it comes down to appetite, but people can't say that. If you didn't want it, you wouldn't eat it.

Obesity is the culmination of many negative choices over years much like diabetes. Yes genetics play a part but so does education and healthy educational choices related to food.

"It takes a month without food for us to die": actually it takes longer in some of us lucky individuals. I survived 70 days with no calories, admittedly my body was incredibly unhealthy by the end but I survived and I'm still alive thanks to my tube feeds (I'm fed directly into my jejunum) My starvation wasn't intentional, I have gastroparesis and it suddenly worsened a ton and my stomach stopped accepting any foods and very, very little water and it took me a lot of time to get someone to help. This is why I consider myself a very lucky human being, especially as I'd gone years on a very low caloric diet so I starved on an almost empty tank. I'd love to have my genes tested to see what's there in relation to my abilities to starve for longer than normal, as I'm extremely energy efficient even now (4 years after my starvation). I need far fewer calories to maintain my weight and if I get even a few more calories than I need I get fat quicker than I should do and really struggle to lose it. My diet is fixed as it comes in a bottle (thanks to the wonderful NHS) that I remove 100ml ish (depending on activity level) with a syringe so we know almost exactly how many calories I'm taking in. My drs and dietitians are a little bewildered by my caloric needs (as I'm pretty active and not at all sedentary, even though I'm disabled in other ways than my gi system issues). I'm just thankful or I don't think I would have survived the end of 2014!

To the stress-out guy at the end: Don't get married, no kids and don't get a job!

Also if you are poor you live with a lot of stress. Not good if you stress eat.

It depends on the definition of over eating. I could eat 20oz of popcorn and only eat about 2000 calories or I could eat 20oz of peanuts which is about 3200 calores(using large quantites just for comparison). The popcorn is will be much more in volume but only 2/3 of the calories that are in the peanuts. I think the issue is people don't realize the amount of calories in individual foods. You may not eat a lot of volume, but calories may be much higher tha you realize. It's kind of like the "whats heavier a pound of feathers or a pound of bricks" they may weigh the same, but the density is substantially different.
