Difference Between Losing Weight and Losing Fat

You can be loosing weight without losing fat and you can be losing fat without losing weight. Many people are losing weight but they are not losing fat.  The fat is still there though they appear to be gone.  How is this possible?  Fat is stored in fat cells in the body as chemical energy. When the number in your scale goes down,  you would have lost some percentage  of fat indeed though most of the weight loss may be water and glycogen.  In any case, the fat cells may be shrinked but the cells themselves are not gotten rid off and because you may go back to your normal eating lifestyle, the fat cells will eventually be refilled and if you are not careful, more fat cells will be created and alas! there is your old body staring at you in the mirror again. The reason is simple.  It is because your defense is down. We have no control over most things that make up our basal metabolic rate (BMR) I. e what is used to measure your metabolism while your body isn't engaged in any external activity.  But their is one thing that make up the BMR that we can control and this is muscle mass. One pound of muscle burns nine calories more than one pound of fat. This is why I said you may be gaining your weight back because your defense is down. Incase you have not gotten the point,  let me break it down better for you. Most people go for diet plans e. g Atkins, that make them lose muscle mass as well as fat.  Hence, they are not able to fight back when Mr.  fat comes back to try to regain it's former colony.
           Again, muscular strength and endurance training boosts metabolism for up to two hours after exercise. And note that muscles occupy fewer space than fat, so that you will still end up slim. Guess what type of food you need the most when doing muscle training? No!  not carbs,  proteins! Do you know you spend more calories when digesting proteins than other food groups? Yes!  it is a fact, not a theory. But, this is not to disregard aerobic exercise or eating carbohydrates.  Aerobic exercises help us burn calories and carbohydrates are the main source of energy to our body system. I will go into details later but first of all, what did I meant when I mentioned that you can lose fat without losing weight.  This happens when you are able to replace your fat composition with muscle composition. Check the image below.


Note: both weighs the same despite varying degrees of fat composition.

Benefits and risk of exercises in old age..

By -
The veterens now provide competition at local , national and international level for an increasing number of old athletes. However there is a certain risks associated with exercise for older people that can be minimized by adequate medical screening as well as an awareness of, and appropriate response to warning symptoms. BENEFITS OF EXERCISE Exercise benfits whole body as well as psyche. The most benefits found in cardiovascular system thats why exercise decreased morbidity, mortality, and symptoms, and reduce cardiac rehospitalization. Exercise increased the demand on myocardium improves oxygen utilization, dilates capillaries and improves  the delivery of oxygen and other nutrients to the muscles. Inside the cells  the number of mitochondria increases enhancing aerobic metabolism. Exercise tends to lower the resting heart rate and resultant increased diastolic time allows improved coronary blood flow.. Exercise lowers the blood pressure andreduce obesity, these two ...

7 Common Habits That Lead To Weight Gain

1) Eating Late: It is advisable and recommended that supper should be taken before 7pm in the evening because it aids weight loss. By eating before seven, you are able to fast for like 13-14 hours before taking your next meal ( breakfast). Therefore your body is able to finish digestion and absorption phase before you load your body with another one again. Check out this research from washingtonpost.com: “ For years , we said a calorie is a calorie no matter when you consume it ,” says dietitian Joy Dubost, a spokeswoman for the Academy of Nutrition and Dietetics. “ I don ’t know if we can say that anymore , based on the emerging research. The timing of a meal may potentially have an impact. ”Most of the major studies on late -night eating have been conducted with animals ,night -shift workers and people who , due to a disorder called night eating syndrome, consume at least 25 percent of their daily calories after supper or who wake up to eat at least twice a week . Studies te...

ATHLETES AND RISK OF HYPOTHERMIA

By -
As we know athletes move throughout the world for their competition and training sessions. So they are encounterd by cold weather also and have to manage the risk of hypothermia because Cold weather facilitates the loss of body heat which can reduce body temperature. But it can managed by heat conservation or by increased heat production. Exercise and shivering increase metabolic heat production helping to offset body heat losses in the cold. Exercise increases peripheral blood flow facilitating heatloss, an effect that can persist for some time after exercise ceases. Prolonged exercises may lead to energy substrate depletion which compromise the maintenance of thermal balance during cold. The heat transfer coefficient is mainly influenced by ambient temprature, wind chill and clothing, when vasoconstrictor responses to cold are impaired body heat conservation declines. Chronic exertion impairs temperature control, when heavy physical activity in the cold is coupled with underfeedin...
