In an interesting Swedish article published at https://www.svd.se/overlakaren-traning-ar-ineffektivt-for-viktnedgang the 14th of August 2017, Chief Physician Christofer Grimås at Nordisk Centrum for chirurgie clinic for overweight surgeries, says that “- Exercise isn’t efficient for weight loss”, rather that it is about the calorie intake. Only in rest we need 1500-2000 calories, and depending on your activity level you’ll need even more. Your basal metabolic index can be calculated based on your length, age and average activity level.
“- Exercise is tremendously good in many ways, says Christofer. We are feeling well by exercising. But for especially weight loss it isn’t especially effective. Just compare the time it takes to eat a hamburger, perhaps 5-10 minutes, compared to the 60 minutes it takes to burn the same amount.”
Weight loss is mathematics; what you put in and what goes out, i.e. what you eat and what you burn.
So what are the causes to modern times overweight? The article explains, which I can agree too, that it is the modern food culture in some parts of the world that makes us fatter. Larger portions, over consumption, more sugar and unhealthy fast-food that again in some parts of the world is cheaper than healthy food options.
Christofer rejects the idea that we have differently fast metabolism. “- That isn’t true. We have more or less the exactly same metabolism, but we are born with different amounts of fat cells. The number of fat cells are constant during the entire life, but they increase or decrease in size. It’s that, together with eating habits, that result in how big we are.”
I think this article was too important not to share with you enthusiastic women out there! Exercise is also important of course, and especially strength training, which helps us to increase muscle mass which works as larger engines, meaning it increases the metabolism even during rest.
So the short conclusion is that what we eat really matters to our weight (loss) and health. Exercise is awesome and can make us feel great. Put them both together: exercise + healthy nutrition = the way to optimal health.
