Diet or Exercise For Weight Loss?

Diet or Exercise For Weight Loss?

In today's world obesity is becoming one of the major problems worldwide. While it continues to spread like a pandemic, fighting it is becoming more and more challenging. This is because obesity can only be fought by watching your diet and exercising. And, therein lies the rub "our busy lifestyle". We choose unhealthy foods from fast-food restaurants because it's easier than cooking, and it saves time. This is the same reason why we do not do exercises, No Time! But, what if you only had time for one of these approaches? Which one would you choose? Diet or exercise?
Well, the answer really depends on you. First you should ask yourself, what is it that you're trying to achieve? Are you only interested in losing weight, or you want to live a healthy long life? If your goal is just to lose weight, watching your diet should be sufficient. But, if you want to improve the quality of your life and live longer and healthier life, you should start focusing on exercise, or both.
Diet for Weight Loss In a twelve-week long study done over a decade ago (year 2000), scientists compared the weight loss progress of people on "diet only"programs to people on "exercise only" programs The overweight women in "diet only" program lost 5.5kg (12.12 lbs) and men lost 8.4kg (18.51 lbs). This was accomplished by reducing the caloric consumption of women by an average of 945 kilocalories per day and men by 1705 kilocalories per day.
On the other hand, in "exercise only" group, women lost 0.6 kg (1.32 lbs) and men lost 0.3 kg (0.66 lbs). This group had performed walking and jogging exercises 5 days a week for 30 minutes a day. On average, a woman burned 190 kcal per session while man burned 255 kcal. Women in this program lost about 2% of their body fat, while women in "diet only" program lost about 6% of their body fat. The men in "diet only" program lost about 5% of their body fat, whereas men in "exercise only" program did not see any significant change. As you can see, that eating diets low in calories is much more efficient method for losing weight.
Exercising for better life: Do not let the results from the above study destroy your motivation to exercise. The study did not include any weight training exercises, which are essential to muscle building and losing fat. Exercises have several other benefits than weight loss. A recent study shows that every hour you spend doing exercise, you increase your lifespan by 2 hours. It's not just longevity; it’s also the quality of your life. The more exercises you do, the better your chances of being disease free at the old age. Listed below are some of the advantages of doing exercises:
  • Reduced risk of premature death.
