Logged in to comment and glad someone else got there before me. What about women!?

I agree. I think though the real problem is about sedentary jobs. If your breaks are taken to rest from intensive activity you should get the best of both worlds if you start eating at first break. When I became morbidly obese it was because I took up reading again after years of not doing it. The reason is because up till then I always went for brisk walks in my breaks and suddenly I used the time to read and wound up eating more at the same time and yes I took breakfast. Exercise and diet eventually sorted me out but only after I became ill enough to get motivated.

I love ZOE content and get a ton of value out of your stuff but I have some serious issues with what's (or rather what isn't) being discussed here. Number 1 that people are exercising to lose weight when the majority of every commercial gym I've ever been in is people trying to gain weight or trying to reach an athletic goal. Both of which are almost certainly benefited by eating carbs before gym, as pretty much any PT or sports scientist worth their salt will tell you. And Number 2 that exercise lowers blood glucose intraworkout when it very much depends- I have the luxury of being type 1 diabetic and being able to see what happens when I vary insulin on board, carbs before a workout and other variables and seeing what happens. I've also been olympic weightlifting and powerlifting for close to 6 years and even at 40% of my 1RM I'm almost certainly going to see an increase in blood glucose unless adjusted with insulin, even and including when I haven't eaten carbs for 16+ hours. While things are slightly different for non diabetics you ARE still going to see a bump in blood glucose followed by reduced insulin resistance for the next 12-48 hours as you glanced over for the extreme majority of anaerobic exercise or high intensity aerobic exercise. As you also skipped over in the last minute of the video, glycogen is a huge factor here. I think you're dramatically ignoring the reason most people are in the gym and instead using the effects of activity vs inactivity on postpandrial blood glucose as an explanation for why eating before you train is somehow a bad thing or at the very least you're dangerously reducing the variables involved. tl;dr under specific circumstances (you're doing mostly light to medium aerobic exercise like swimming, jogging or cycling, you're not eating low carb and you're not trying to gain or maintain weight and you're primarily concerned with blood glucose) this might be a useful take but otherwise it's very probably going to detract from your training and you should probably be eating carbs before, and carbs and protein after you work out relevant to your needs and goals.

My fasting blood glucose and HBA1C are great but my need for fuel during endurance exercise is massive and contrary to ZOE recommendations.

Exercise before eating just makes more sense. Evolutionarily, we would have needed to expend energy to get food before eating then eat and relax. Reducing the glucose spikes surely isn’t the priority, rather reducing insulin resistance. Two xmases running, I put on a lot of weight on mother’s cooking. Following that, I deliberately ran in the morning before eating, and the difference was stark. A regular part of my routine became to run before breakfast, although later in the day also good but I would never dream of doing so after dinner. Food interferes with vigorous exercise and experience confirms what I was always told, not to do vigorous exercise foe an hour after eating.

Why would you eat breakfast, that makes no sense. First of all, Intermittent fasting or “time restricted eating” shows health benefits for all by reducing the number and extent of insulin spikes thru the day. Secondly, the body is already fasted and burning fat in the fasted state when you wake up. The first thing the guest said was twice the fat was burned by exercising before breakfast. This is most relevant if you are weight training and trying to build muscle with strength training. More muscle is built if protein is consumed after the workout. You say you cycle home then have supper. So I assume you are having breakfast and supper, and possibly lunch. Bottom line if you want better results, skip breakfast and have your first meal of the day at work as lunch. The guest discusses insulin midway thru the video, and discusses insulin sensitivity and resistance. Later, The guest said the insulin response was far better when exercise was performed before the meal. So Everything you are doing is wrong in the morning when having breakfast before cycling to work. Watch the video again and listen to what he is saying.

To my horror my blood glucose rose during my tennis session peaking at 11 mmol! (Diabetic levels) when I finished my session. That quickly crashed to 3.3 mmol. I then had a big bowl of pasta which got my blood sugar levels to normal levels (around 5 mmol). I now take Lucozade during my morning exercise session which has helped with my performance.

I'd like to add that 1) even the lean people who exercise daily, especially CrossFit or endurance workouts i.e. not elite level athletes, having breakfast before exercise or soon after can make a big difference over a longer period of time. 2) you don't need to have a full breakfast but getting like ~200kcal before / during training is beneficial for those lean individuals.

@@stephenwilliams3213 That’s exactly the point. That’s why there’s still so much medication out there that hasn’t been tested in women. We know that women are more complex, but don’t we deserve the same level of care? If this isn’t systemic sexism, what is?

This podcast was very useful as I am an on intermittent fasting so eat nothing from 8pm one day until mid-day the next. I have therefore been having my thrice weekly exercise sessions well before eating anything. I have found it just as easy and indeed my mood is lifted as I feel virtuous! By the way, I'm also losing weight! Janet

How about exercise before AND after eating? What about 'eating' (a suitable, from scratch, home made 'shake') whilst on the move?
@andreabirtwistle6847

A shake, if made with fruit, will raise your blood sugar significantly unless you add protein and fat, too. However, the exercise will bring it back down more quickly than not exercising. I assume you won't get the extra benefit that exercising fasted would bring. As seen in the male only study.

Agreed. The cycling experiment is a cardio exercise so uses less muscle energy than heavy weight lifting for example. And it depends on how hard the participants were cycling!

For me exercise intensity matters. Low intensity exercise like swimming or walking reduces my glucose levels. However running, resistance training or playing squash make no difference except to raise glucose levels a little for a short time. I do wonder about how generalisable this result is.

one thing coverred is that as an athlete wanting max performance, one does not eat a heavy meal e.g full English breakfast. The reason much energy blood chemicals go to the stomach to digest the food hence why we feel tired after lunch ( graveyard shift for first lecture after lunch wil attenddees falling asleep in the lecture room)\. |For max best effort, one neds easily digestable foods only |& at least 1-2 hours gap before hand. I woouuld love to hear the experts put the exact science behind what is known

I primarily trail run around 30miles a week and only recently started doing my 3 midweek sessions (around 1hr) fasted on just a black coffee as opposed to eating my breakfast an hour before and have noticed a few things. 1. I procrastinate less than before and find it much easier to get out the door. 2. I’m less hungry throughout the day. 3. I snack less. 4. Much less of a crash in the afternoon 5. Less brain fog throughout the day. 6. I have lost noticeable amounts of fat. 7. Breakfast tastes even better 😆 My weekend long run tends to be over 2hrs, I eat around 2hrs before I get out to allow digestion. May actually start trying them fasted but start fuelling from an hour in.

Fascinating research, thank you for the podcast. I'm a type 1 diabetic so am aware that doing exercise increases my insulin sensitivity as I have a real time readout of my blood glucose on my phone and can see it dropping. But I've never tried doing exercise without first eating (and without taking any insulin) as I've always thought this could be dangerous for me but perhaps I should try it.

He is speaking about healthy subjects. In your case, I would be very careful. Exercise can send you hypo unless you adjust your basal/bolus insulin. Certainly exercising is very good for you, especially long term.

Also, as a type 1 diabetic (like myself) you probably don’t need to lose much weight, so burning fat is less important than keeping bs level from going high.

Put simply : Not eating before exercise = more fat loss as the body is using glucose as an energy source and when this runs out it breaks down the fat and coverts it into energy. Eat before exercise = the body is actively in the process of breaking down the food and not using the glucose reserves = less fat loss BTW the body cannot do both at the same time!

At the moment, until this same study is performed using both pre and post menopausal women, this information is only relevant to one half of the population - men. I would suggest that you make this clear in tag line. Please consider waiting until you have performed the same study on women and then report findings as this would be the most interesting and relevant information.
