You Can’t Outrun A Bad Diet
The debate has been going on for years. Many have assumed that a lot of physical activity alone can reduce weight. Is common to hear people say they’ll have to work out an extra half hour after consuming a high calorie treat. But does exercise reduce weight.
A recent report from the UK’s Academy of Medical Royal Colleges described ‘the miracle cure’ of performing 30 min of moderate exercise, five times a week, as more powerful than many drugs administered for chronic disease prevention and management.1 Regular physical activity reduces the risk of developing cardiovascular disease, type 2 diabetes, dementia and some cancers by at least 30%. However, physical activity does not promote weight loss
Do you think our physical activity’s have change over the last 30 or 40 years? Studies show they have not, yet obesity and diabetes has risen substantially. What has changed is our diets and our becoming more dependent on processed food.
According to TheLancet global burden of disease reports, poor diet now generates more disease than physical inactivity, alcohol and smoking combined. Up to 40% of those with a normal body mass index will harbour metabolic abnormalities typically associated with obesity, which include hypertension, dyslipidaemia, non-alcoholic fatty liver disease and cardiovascular disease.3 However, this is little appreciated by scientists, doctors, media writers and policymakers, despite the extensive scientific literature on the vulnerability of all ages and all sizes to lifestyle-related diseases.
The common knowledge today is that weight is controlled by your calorie intake and many believe wrongly that obesity is due to lack of physical activity.
This false perception is rooted in the Food Industry’s Public Relations machinery, which uses tactics chillingly similar to those of big tobacco. The tobacco industry successfully stalled government intervention for 50 years starting from when the first links between smoking and lung cancer were published. This sabotage was achieved using a ‘corporate playbook’ of denial, doubt and confusing the public.4
The message has been that all calories count. That is simply wrong. It is the type of calories that make a big difference. Calories from sugar go into producing fat on our bodies and a feeling of hunger. Whereas calories from fats induce fullness or ‘satiation’. Counting calories doesn’t matter on a low carb diet.
A large econometric analysis of worldwide sugar availability, revealed that for every excess 150 calories of sugar, there was an 11-fold increase in the prevalence of type 2 diabetes, in comparison to an identical 150 calories obtained from fat or protein. And this was independent of the person’s weight and physical activity level; this study fulfills the Bradford Hill Criteria for causation.5 A recently published critical review in nutrition concluded that dietary carbohydrate restriction is the single most effective intervention for reducing all the features of the metabolic syndrome and should be the first approach in diabetes management, with benefits occurring even without weight loss.6
Low carb, high fat diets are becoming more and more popular. the results of these diets speak for themselves. Not only that, most people who loose weight with these low carb diets realize that is a healthy way to eat for the rest of their lives.
It is time to wind back the harms caused by the junk food industry’s public relations machinery. Let us bust the myth of physical inactivity and obesity. You cannot outrun a bad diet.
The bottom line here is that exercise alone does not loose weight over time. You must get rid of the sugar in your diet to loose weight and keep it off. A proper diet combined with exercise will loose weight the fastest.
