Have you ever wondered how our life in those old days was?

Have you ever thought where did all the stuff about food and exercise come from? Internet, media and magazines are full fo various types of diets, exercises and advice. What's the research? Who were the scientists and people who questioned and how did stuff happen? Sometimes, I think that during those old days and I am talking about the 70s and 80s here, we never thought about drinking skimmed milk. Maybe it never existed at that time! There was only full-fat milk; there was no low-fat cheese, and there were no protein bars.

Did Diets and fitness industry really exist?

There were very few diets. In fact, during those old days, there were one or two different diets. You could go on the whole diet or fitness diet. Health and wellness profession kind of didn't exist. There were hardly any gyms maybe a couple of them in the entire city where exercise programs were designed by being bodybuilders who came from Hercules movies.

There was hardly any information really about being healthy, fit and strong back then. It was all like common sense or even less than common sense. Everyday life didn't allow us to be overweight, to be unwell because we ate with common sense and we moved our bodies because we had to walk.

How was life then?

You put it back in my day. I had to walk to school, lift heavy things at home. I had to use my fingers to push the dial on the phone to call somebody and reach our black and white TV to turn it on and off. Cars didn't have power windows, so I had to use the power of my hand to pull the window up and down. I rode the bicycle and burnt so many calories every day.

There were no escalators; there were none of those people movers at the airport when you have to walk from one gate to the next. Isn't it beginning to sound interesting? We used to lose all those calories which we would intake.

So we didn't have any obesity challenge. There were a few overweight people and coronary heart disease, which has always been the biggest killer in the world today. But it didn't kill that many people. Yes, we've had lung cancer, but that was from people who smoked.

Do you wonder why we put on weight?

We now have the statistics which show the weakest human race ever in history. We are really fat, and you know what disease do we have? It's called inactivity diseases. I'm going to say that again that conditions such as coronary heart disease for most people are simply an 'inactivity' disease. If you were healthy, fit and strong, you wouldn't get it. Type two diabetes won't exist.

There was, and there's always been the type one diabetes. But type two diabetes used to be called age-onset diabetes because older people who got fat, got it. And they got fat because they became inactive.

How strange it is that our children are suffering nowadays?

We now have type-two diabetes in children because they are inactive. They have osteoporosis, which is a bone wasting disease. It didn't exist because women lifted heavy things. Children, in old times, used to lift heavy, put rubbish bins, lift logs, suitcases etc. Remember, suitcases didn't have wheels, so you had to pick it up. I don't think they even exist anymore.

What's happening now, and how was it like that time?

We don't move, carry or lift things anymore. We sit on the chair or lie down on the couch. We don't even need to move to turn TV or light switch on-off because of remote control.

Now you can sit on the couch with your smartphone, order pizza online; the person will knock at the door. You pay him and eat your pizza on the couch. We have become fat, sick and weak because we are inactive.

In those old times, what about the food thing? People never drank skimmed milk. They ate fat on their meat, and they ate high-fat cereals and drank hot and chocolate shakes.

We used to eat a lot less at that time. There was no such thing as a mega meal or a supersize. Similarly, in the supermarkets, family packs were not that big as they are today.

We had chunky bars because they're the smaller ones. Now you get huge ones, and there is no medium size anymore. So our meal sizes, our serving sizes have gone from small to large. When you went to the movies, could you ever buy a litre of coke? The answer is no. Even the bag of popcorn has grown big! When you went to get ice cream, it was one scoop, and it was a small scoop. Now when you buy ice cream, it would come in a big pack, which means you will consume more, meaning more calories.

You receive more information than it has ever been about food and exercise, but we're the fattest we've ever been. Let's go back to when we weren't fat and sick, and have a look at what we were doing. And guess what? We weren't eating low-fat food. We weren't consuming protein bars and spending a hundred dollar worth pots of protein powder.

How did the guys look at that time? They had muscles, and they looked amazing.

They were lean because they were active and lifted heavy things. They ate food to suit their activity level. So if you didn't do very much, you didn't eat very much. But if you did a lot of physical activity if you're a farmer or you had a construction job where you were active all the time, you ate an enormous amount of food and burnt it off.

What if we use our common sense or logic!

If you are a consumer of products such as fat burning pills, protein powder etc, don't you think you need to be aware of human physiology? How our body works and how much protein and carbohydrates it actually needs? Rather than spending money blindly without knowing whether you need it or not, don't you want to find out whether you get a sufficient amount of macronutrients in food that you eat or not?

Think about it. What's logical? Walk the stick, play with your kids outside, park your car a long way away from the shops and walk-in, carry some stuff, lift some heavy things. If your life doesn't involve lifting suitcases anymore, you're going to have to lift something heavy, so you don't get osteoporosis, and you don't get overweight. And if you want your body to be a fat-burning machine, it has got to be fit.

We used to have a life where we would run to get the mail. We would run in the playground in the school. We would run because it was part of our life. What I am trying to share is that we would get puffed.

What if we could stay fit and strong by lifting weight and getting huffy-puffy!

So if you want to get puffed and become a fast fat-burning machine, you need to move your body. If you want to be strong, have a fast metabolism, and you don't want to get osteoporosis, you need to lift heavy things.

However, if you never lifted heavy items for hours in the gym, what you need to do is make sure that you get fit by getting puffed, strong by lifting heavy things and lean by not putting enormous amounts of food into your body. If you don't move very much, don't eat very much. If you do lots of physical work, you can eat more. Let's have common sense and be logical.
