Yes indeed it can. If you reduce the number of calories that you take each day and make sure that whatever you take in are only healthy calories, you will lose a substantial amount of weight. If you can go further and combine lower calorie intake with exercise, there is no reason why you should not achieve your desired weight in a short time.
Less calories in your diet means that you will, in your day to day activities, dispose of the excess as you burn them to provide you with energy. The more of your calorie intake that you burn, the more weight that you lose. This means that if you take in fewer calories and burn most of them, you will be on your way to weight loss.
The question then becomes how many calories one should take daily to effectively lose weight. There are no strict guidelines, and you should be wary of anyone who says that there are. Our calorie needs are unique to our body types our weight, our height, our metabolism and our daily activity. This means that in the same fashion, the number of calories that you should reduce in your daily diet will vary from person to person.
If you asked how many calories you should eat in a day and how many you should burn, the answer you get may be something like If you want to lose 1 pound of weight in a week, eat 500 less calories every day. Because 1 pound of fat equals 3500 calories, you will have achieved your 1 pound less.
This may be misleading. It does not take into account specific body type needs. Are we talking to someone who weighs 100 pounds and who gained some extra weight over Christmas or are we talking to someone who weighs 225 pounds and has struggled with weight loss and diets for years?
The heavier person may achieve their ideal weight at about 170 pounds. Will they achieve the one pound loss of fat in 1 week by taking off 500 calories from their food? What id for them, just basic functioning requires more?
To help with these variations, there are very specific calorie counters available that factor in all these variables and give you your ideal weight as well as how many calories you should take in every day and how many of those you should burn.
You should know, as mentioned earlier that even though you know how many calories you should burn to lose weight, you should eat the right kind of calories. Calories that come from refined foods are unhealthy. Healthy calories are the ones that come from food sources in natural form, or at least as natural as they should be.
Many snacks, for example, and even shakes that are recommended for weight loss come with more refined sugar that is recommended for good health. Fruit or vegetables that would serve the same need have these sugars in a more natural form that is just enough. You should be aware, by the way, that 80% of weight gain has been attributed to refined sugars that lurk in things that you enjoy every day, even those that are termed healthy.
