Infectious diseases are on the decline in the developed world whereas they still remain a great burden in the developing world. Chronic diseases such as hypertension, diabetes among others, however, continue to affect both the developing world and the developed world. This situation has become increasingly worrying given the present rates of morbidity and mortality related to chronic conditions.
To answer such a question, you have to reflect upon how our present times are different from the times of old. Obviously, the food we eat, our activity levels and other lifestyles are unhealthy. It is very common to see people consume so much of calorie containing foods yet do so little of activity. This lifestyle of eating junk foods and being sedentary fuels weight gain. Weight gain is the appreciation of your weight relative to a marked baseline. This happens as a result of loading the human body with more carbohydrates and fats than that required for the relatively inactive consumer. The human body converts the excess glucose from these foods into glycogen to be stored in the adipose tissues under the skin and this is what mostly causes weight gain.
How then does all these fit into the picture of obesity and weight gain? Well, obesity by definition is body mass index greater than or equal to 25. The body mass index is defined as weight (in kg) divided by height (in m2). Clearly, the weight of an individual with recourse to their height relates directly to obesity.
As already stated, the root problems in weight gain and obesity are diet and the level of activity. And to solve the problem of obesity and its attendant health complications, diet and exercise must that we are what we eat cannot be overemphasized but be appreciated and accepted. People with no knowledge about nutrition or those with some knowledge but fail to adopt healthy dietary practices, eat anything sweet, palatable, nice etc. Such people are unlikely to ask the question as whether what they are ingesting is needed by their bodies or even whether they are in the right quantities needed for healthy growth and development. The result as mentioned is more or less a flooding of the body with what it has no immediate use of other than storage which increases weight and the risk for obesity and serious chronic conditions.
People who are already obese or overweight, there is hope of recovery back to normalcy. It is often a combination of diet and exercise. Overweight and obese people ought to be committed to the goal of losing weight and the schedule adopted for such a goal. Continuity and consistency is key for the success of any weight loss endeavor. Experts advise that weight should not even be lost at once in an attempt to correct obesity; it better be gradual to be effective and sustainable.
The journey to weight loss is definitely not a sweet one especially physically; lifestyle modifications, modifications in diet and level of activity is almost impossible unless one is determining to reach their goal. It comes with stress and sacrifice yet it offers fruits of joy, admirable shape, and good health once the journey is completed. And once completed, there is the need to continue to demonstrate discipline in diet and level of activity to prevent relapse.
Regarding the specifics, it is beneficial, health wise, to emphasize the intake of fruits and vegetables, limit the intake of fats, control the intake of calories among others. Fruits and vegetables give the human body vitamins and minerals; these help boost the immune system for a healthier life. Limiting the intake of especially saturated fats help reduce the level of fats stored in the body and as such, helps with weight management. Soft drinks often contain enormous amounts of calories; it is necessary for consumers to examine nutritional contents of such convenient foods as energy drinks, to control their calorie consumption. On exercise, consistent 30 minutes’ aerobic exercise thrice a week is good at reducing weight.
