Weight gain arises from the consumption of energy in excess of body needs. Two main factors govern weight gain, genetics and the environment. The environment refers to energy intake (diet) and energy expenditure (physical activity or exercise).
Obesity or excessive weight gain adversely affects the function of the heart and is an independent risk factor for cardiovascular disease.
Through an energy-deficit diet and exercise, it is possible to achieve significant weight loss. Weight loss is known to decrease blood pressure and fasting blood sugar. It can improve or prevent many of the obesity related risk factors for heart disease, such as impaired glucose tolerance, type 2 diabetes mellitus, hypertension and dyslipidemia.
Obesity is also associated with altered lung function. It can interfere with breathing, especially during sleep and result in snoring. Over time this may lead to right sided heart dysfunction. All these amongst others, underscore the need to adopt healthy eating habits and an exercise culture.
You can adopt healthy eating by increasing your intake of fruits and vegetables. Reduce fast foods intake as they are high in fat and salt. Diets high in saturated fats and low in fiber are not heart healthy. It is also important to eat less processed foods as they tend to be high in salt. A high salt intake is associated with an increase in blood pressure.
The health benefits of moderate intensity exercise such as brisk walking for about 30 minutes on most days of the week applies to everyone.
Behavior modification is vital to starting and adhering to a weight loss program. It is a good start when you are able to lose weight. Maintaining the weight loss is even more important for sustained benefits. A healthy lifestyle is well worth the effort. Start today to lay a foundation of good health now and in your old age
