The food and drink industry is not the only problem.
An increasing proportion of jobs involve zero exercise. With the result that the harder we work the less we move.
General Lack of Exercise
Not just sedentary jobs but also sedentary past times are exacerbating weight gain at all ages. However, it becomes increasingly important as we age for over the age of 50 we tend to lose muscle unless we do resistance exercise to retain it. Less muscle mass directly reduces our resting metabolic rate at a nominal 50 calories/day for each pound of muscle lost.
That may not sound much but 2 pounds is 100 calories/day and over one year 36,500 calories, roughly equal to 10 pounds of weight gain/ year, if everything else is kept constant. What is worse is that this can be the start of a vicious circle that becomes increasingly harder to reverse.
Stress and Sleep
Too much stress and too little sleep both tend to increase weight gain and lead to the production of cortisol which in turn can increase visceral fat and result in Type 2 diabetes.
Being able to manage our stress levels and ensure a good night’s sleep of ideally 7-8 hours is fundamental to our wellbeing and aids weight management.
