Many people seem to believe that our modern life is too sedentary compared to our forefathers. I even hear it that when I was a kid we got out more and had more activity and that is why we weren't fat then. Well the fact is, you will burn around 1500 calories a day just by staying in bed. If you don't compensate for those calories by eating less then you will lose weight. If you eat more calories, you will gain weight. It is evident that our modern civilisation is eating more calories than we burn and it is worth investigating why.
If you exercise more, but don't change the composition of your diet, you are likely to keep gaining weight. The reason is that you are eating the wrong things. What has changed in our diet?
- Easy access to refined sugar!
- Poor health advice, based on flawed studies, telling us to have less fat in our diet.
Eating carbohydrates at the rate we do now overrides our natural mechanisms and balances. Our biology cannot cope and we store more and more fat while craving more carbs. On top of that our high carb diets are creating insulin resistance in us. Two hundred years isn't enough time to for our species evolve to such a radical change in our eating habits.
Eating fat, on the other hand, gives our body a more efficient way of getting the energy it needs and we feel satiated on less calories.
So, is it necessary to exercise to stay lean? Not at all. We don't even have to starve ourselves if we eat the right food. The only reason our society is getting fat is because we have our food pyramid upside down. I'm losing weight without having changed my level of exercise. I've just stopped eating carbs.
Note: I have started exercising more in the last month. But I need to emphasise that is as a result of having more energy and because, having already lost weight, I had a desire to get into even better shape. The weight loss came first, extra exercise came second.
