Fast Exercise with Michael Mosley webchat

Nothing is going to work for everyone but at a bare minimum I think it is useful to understand what exercise does and why it so beneficial. I have spent 2 years researching this book with the help of some of the world's leading experts. I hope it will help add to people's long term health. In the UK we live as long as other's in Europe but spend longer than most in a state of ill health. It can be prevented by life style changes, at whatever age. On that note I'm afraid I have to run (yes, literally).
Good bye, good luck and thanks for your questions

Hello Michael I'm afraid it's another fast diet question. I find even if I eat fruit, veg, yogurt etc all day long I still feel hungry and only carbs satisfy me. How can I make that work on a fast day?

Try eating protein instead ie fish, meat, nuts

I'm sceptical about this, as I am about the 5:2. Losing weight, keeping it off and becoming and staying fit is not rocket science. It does not require the input of a celebrity doctor or a fitness guru. It does, however, require focus, motivation and discipline. Many of us do not have these qualities in large amounts, however.

If you want to do it, you will, regardless of faddy regimes.

The reason why scientists spend so much time and money researching new approaches is because so many people find standard advice hard to follow. It is like saying, "the way you play golf is hit the ball straight into the hole". Easy to say, for most people impossible to do. People do not want to be fat

Remember reading piece by Andrew Marr which told how he had tried intensive bursts of exercise on his rowing machine.....then he had a serious stroke. Bit off putting that.

Very putting off. But he had been under a lot of stress and had had two previous strokes. His case is tragic but not typical

I have dodgy knees and can't do anything that involves "jumping" of any sort. Like the idea of short bursts but not sure what's available for me to do.

I also have a dodgy knee. I get my HIT by non-weight bearing exercises like swimming and cycling. I do strength exercises (10 in 7 minutes) that are not dependent on jumping. The point i make in the book is that scientists who study exercise are keen to develop new ways that actually work. The standard advice needs updating. There is a huge gap between what scientists in the lab know, what doctors know, and what the general public knows

Wondering what's next in your quest to find the holy grail in optimising our health and fitness? If I were you I would looking at popularising veganism/vegetarianism, since a plant based diet is increasingly being advocated as the most healthy. Or don't you agree?

You have read my mind. I have just finished a 2 part series on Meat for Horizon that goes out in the spring that looks at exactly this question

Another myth is "Starvation Mode", the claim that if you skip meals your body will hold onto fat. Intermittent fasting has been shown to increase the metabolic rate.

Energetic activity makes one hungry. It's not a good way to lose weight. Steady, regular, gentle exercise is better, and eating less. This is just another quick fix idea that will fix nothing, like all its predecessors.

Actually that is a complete myth. All the studies show that Fast Exercise reduces appetite, not just straight after but for 24 hours. Moderate exercise makes people hungrier, which is why people who do moderate exercise like jogging almost never lose weight (they eat more). Walking doesn't trigger appetite but unless you add a bit of intensity you won't burn fat. The book has loads of references to scientific trials that justify these claims. It is also endorsed by 3 of the world's leading exercise experts

I saw some crazy person one on a TV programme last year doing this fast exercise and looking like death in the process - I think it was probably you? Now, I do believe in the benefits of the 5:2 diet, but to exercise like this seems somewhat odd, nay dangerous and I don't think I will be taking it up any time soon. I shall just plod on with walking, cycling, gardening and maybe a little gentle zumba'ing, unless you can persuade me otherwise!

The latest version is more sedate. Walking is great, but if you actually want to burn fat and get improvements in your glucose metabolism (how well your body deals with sugar) you need to add a little bit of intensity. Not extreme, get the heart rate up a bit. I have spent 2 years researching this book and I hope you will find the science as fascinating as I do. Give you something to tell kids/grandkids!

Difficult to ask questions without buying the book and seeing what the exercises are . However, as I tend to hang on Mr Moseleys every word [haven't tried the 5:2 diet yet but planning to] I'll try to get hold of it and pass on what it says.

Do. You can pick up Fast Exercise online or at a supermarket for around £3, cost of a sandwich or large coffee. I can promise the effects are more beneficial and last longer!

Mobility impaired by arthritic hip and aftermath of broken foot - how to exercise??

That is tough. I recommend walking as much as you are able and doing upper body strength exercises. Yoga is also good if you can manage it

I believe you are an advocate of the 5.2 diet. Do you think this is safe for older people?

Yes, I came up with the expression "5:2" (my book is the Fast Diet) and I popularised the approach, based on studies done by scientists in UK and US who I interviewed for the BBC science series, Horizon. It is safe for older people but oddly enough, after the age of around 70, being slightly overweight is no longer dangerous but can be protective. So depends on how much you want to lose. I wrote the Fast Diet because i was worried about becoming diabetic. Intermittent fasting has been shown to reduce the risk of this and may reduce your risk of dementia (it does in rats; human trials underway)

Is it safe for people with heart problems like cardiomyopathy ie. hocm (on meds. for high b.p. and betablockers to slow the heart? I started the fast diet months ago and it works - I have lost over 2 stones and find it fairly easy to keep it off but I dislike exercise and would love to try this but am very wary of "sudden death"....

Congratulations on the weight loss... If you have anxieties then check with your doctor but the exercises in Fast Exercise have been tested on people who are overweight, unfit or diabetic. They have also been tested on people with history of heart disease and stroke. Start with Fast Walking, put in some stairs, do Fast Strength. Probably avoid weight training as heaving weights puts up BP

Reading all the comments makes me realise I must be quite fit! Aged 65, not any medication, last year I got my weight down to the right weight range for my height using the 5:2 diet. Bunion on my right foot a bit sore sometimes but that's the only problem. Have bags of energy. However - the problem - how do I reduce my waist? I read somewhere recently that sit-ups are a waste of time. Any suggestions for reducing my waist? I don't go to the gym (and don't intend to) and I don't have any equipment at home. The plank is supposed to strengthen the core muscles and when I remember I try to hold in my tummy muscles when I'm out and about.

The advantage of HIT (high intensity training) is it leads to the production of hormones called catecholamines (adrenaline and nor adrenaline) that target the fat cells in your tummy. So you lose weight round your tummy even if you are not exercising that area ie if you cycle. In Fast Exercise we have a range of exercises you can do in less than 7 minutes but which will reduce gut fat

Anywho, talking about sweat (as we were) anything us Mid-Lifers should take into consideration when considering HIT? I can "glow" for Team GB putting on the dark wash. Worried I may spontaneously combust if strenuously exercising too!

The workouts are really short so you don't have time to sweat. I never bother to get into gym kit. I have done our workouts in a suit. Your heart rate goes up, but your temperature doesn't

I have just ordered the new book and am looking forward to getting started. In the meantime I want to make sure I am doing the diet bit right. Are you meant to fast for two DAYS? Or two 24 hour periods? I have found it easier to fast from lunchtime to lunchtime as by having the meal before 1pm on the first day and after 1pm on the second it's easier to do the 24 hours when you just have to split the calories between dinner and breakfast. But a friend told me this was all wrong and I would lose weight faster if I did from after dinner one night (say Monday night) until breakfast two days later (say Weds so therefore fasting on Tues) - making it a total of about 36 hours. Does this really make a difference?

I think you have to find a form that works for you. We are all genetically and emotionally different, so what works for a friend may not work for you. The fastest way to lose weight would be to do 4:3 ie cut your calories to 500 cals 3 days a week. Takes a couple of week to adapt

Is there a risk of stroke with bursts of high intensity exercise? I am thinking Andrew Marr.

Andy Marr was under a lot of stress and had had 2 previous, silent strokes. The main cause of stroke are smoking, high blood pressure, being overweight, lack of exercise. Once you have had a stroke that has weakened your blood vessels then simply turning your neck or sneezing can trigger another one. Exercise, intense or otherwise, is the best way of preventing you having a stroke in the first place
The exercises in Fast Exercise have been tested in the lab to ensure they are safe for people who are older (ie 60 plus), overweight, diabetic. DO NOT DO A DIY VERSION!
