True it is not funny
I collected a new home safe for a friend last week from Jumbo.
They had preloaded on a platform truck so I pushed it to my car and picked it up but I could not raise it high enough to get it in my car. I had to get a couple of the assistants to help me.
According to the label it was 60kg.
60kg is a lot! Iād even struggle with that.
Well you are over 50 
My sister was diagnosed with Leukemia. She was dead within six weeks leaving teenage/young adult children.
She was fit, healthy and not overweight.
Something like 40% of cancers are basically pure bad luck.
Itās a shame many people donāt do anything to reduce the other 60% or heart disease etc.
Calisthenics is just a fancy word for exercising using your body weight.
It would probably be months or years before you could achieve any exercise which would have the ladies swooning.
It starts off with just push-ups (on your knees if need be), dips (using a couple of chairs), planks and leg raises (with bent knees)
What is good though is the progressions are noticeable, even after just a couple of weeks - a few more reps, a harder push-up variation and so on.
Itās much better than something like Cross-fit for when you are older as movements are slow, smooth and controlled so you are less likely to get injured.
You really donāt need instruction to do a push-up and there are lots of You-tube videos detailing what exercises to start with and I havenāt really found a bad one.
You misunderstood what I wrote. I was talking about the extra calories continuing to be burnt after exercise. Probably around 15 calories after a half a hour walk.
But even if I was talking about calories burnt due to the actual energy expended during exercise, calories expended does not equal calories of energy in fat burnt.
It doesnāt work like that even though Coca-cola etc have convinced people like you that it does.
We could extrapolate your flawed thinking with a real -life example.
I used to run around six hours a week, up hills. This burns roughly 1250 Calories going up and probably around 600 or so going down. Assuming I started and finished in the same place, the total calories per week would be (1250x3) + (600x3) = 5,500.
So, you are saying that your 72,000 calories burnt per year giving you 10Kg body fat over year.
(7200 cals per kg)
My 286000 calories should give me 39Kg fat loss per year based on your logic.
Thatās more than half of my body weight.
Actually, in reality my weight didnāt change over that time, at all. Perhaps up or down a kilo or two depending on sweat loss, muscle inflammation etc.
A lot of people just want to āenjoy their livesā, and itās only once theyāre diagnosed with something major like cancer that they decide some amount of sacrifice is worth living longer. Also, I suspect everyone knows someone who drank and smoked too much and still lived to a ripe old age. Itās easy to think āIāll be like Grandpa Joe and live to 100ā.
I agree with wanting to enjoy life.
Personally I think Iām pretty healthy for my age (baring unknowns) but I donāt feel I make a single sacrifice to reach that end.
Iāll let you do the talking.
Better than you doing it. Same for the maths.
With your example, anyone taking any serious exercise would magically disappear in a couple of years.
Grandpa Joe probably had a more strenuous lifestyle than today. Walking to school, caught public transport, ran after chickens, and had harder daily chores. He certainly didnāt sit in front of a screen all day or sit staring at the Bakelite telephone.
Also, a lot less processed food. There is growing evidence these are massive culprits in poor health.
I am not sure about evidence.
Correlation is not causation.
Donāt get me wrong, I eat fresh foods whenever possible
UPF manufacturers want you to love their product and buy and eat more of it, again, and again.
This is fact.
They have people working for them to design new foods with a particular mouth feel and sound which releases pleasure responses.
Take Pringles for example:
Take a bite and there is a satisfying crunch and then the more-ish fat/carb combination (think donuts, ice-creams, chips etc).
But, then they dissolve away in your mouth. Thereās none of that chewing which you get with normal food. Itās already broken down into a sludge before it reaches your stomach.
I know people who can eat a whole tube of Pringles in one go. Thatās 1000 calories - getting on for a third to a half of all the calories we need in a day.
But this isnāt a meal replacement, itās extra. Itās a āsnackā.
A 25g bag of Walkers crisps are also considered UPF but their crisps have been around for around sixty years so arenāt UPF by todayād standards. This bag contains 130 calories.
People eat a whole bag of these too but they contain around 1/10 of the calories of the Pringles and people really donāt eat eight bags in one go.
Thatās one of the problems with UPF. There are many more.
Itās probably a bit more complex than that. While processed foods werenāt as commonplace back then Iām not sure all the stodgy, high carb foods people ate a lot of were very healthy either.
I donāt think it is UPFs that is the problem, it is the proportion of carbohydrates they contain. As a T1 I look at the food labels and I put a lot of stuff back on the shelf because the amount of insulin I would need to take to compensate.
If people really want to lose weight the best way, IMHO, is to cut the carbs. Iām not advocating no or low carb diets, just reducing.
You can also lose the will to live if you are constantly obsessing over whether something is healthy or how processed it is. You have to enjoy food in all its guises, good, bad and naughty. This is one of the (many) reasons I gave up competition swimming when I was younger. I spent best part of a decade boring myself to death with measured food groups. 
People werenāt so overweight back then. Sure, some of those foods were unhealthy but it was difficult to eat too much of them without feeling overfull.
Youāre coming from the viewpoint of someone with a medical condition which isnāt really helpful here.
It would be like a coeliac telling people to avoid bread and pasta.
Simple carbs are a problem as itās very easy to eat too many of them - especially when combined with fats and flavours to make irresistible mouth-feel and taste products.
(No one spoons plain sugar from the sugar bowl straight into their mouth, do they?)
Complex carbs are really important in a balanced diet providing energy to move and fibre required by the digestive system.
Oats are an ideal breakfast.
I agree. Personally I eat anything. Itās the amount that many people have a problem with.
Thereās more to being healthy than just weight though, cardiovascular problems for starters.
Bread and dripping or spotted dick may fill you up quickly but theyāre not great for your arteries.
Thatās true and people generally live longer now but probably more to medical advances rather than better diet.
