You have a medical condition that makes weight loss harder. Any medical condition that affects your hormones (like hypothyroidism or polycystic ovary syndrome), your insulin levels (like diabetes), or your blood pressure (like heart disease) will make it more difficult to lose weight.
Bodies hit weight plateaus.
Our bodies give up water first as they burn stored glycogen. Then, the real work begins. You lose fat, but often we lose some calorie-burning muscle, too. In addition, as we become smaller and lighter, movement becomes easier, so we burn fewer calories.
Muscle Mass
A month or two after you start exercising, your body composition may begin to change. You will likely gain muscle mass and may begin to lose some fat mass. Muscle weighs more than fat, but it also burns more calories.
You can lose weight by eating less, but adding physical activity allows you to burn more calories than dieting alone. Any weight-loss plan that includes regular exercise is not only more successful — it's also healthier. By eating a healthy diet and exercising, you're keeping your bones, muscles, and heart strong.
Some research also suggests that weight loss is about more than the calories a person consumes and burns. The body may change the rate at which it burns calories depending on how many calories a person eats. Therefore a person on a 1,200 calorie diet may burn fewer of them. This can slow weight loss.
It kicks in to preserve and store fat for future energy. Research shows that this happens because the human body has evolved to value storing fat and energy and to interpret a shortage of calories as sign of distress.
Regular meals, sleep, and exercise may all help boost metabolism. Calories provide the energy the body needs, not only to move but also to breathe, digest food, circulate blood, grow cells, repair wounds, and even to think. The rate at which the body burns calories to produce this energy is called the metabolic rate.
Your body is designed to hold onto as much fat as possible to store for times when food may be scarce. That makes losing weight difficult for most people. Factors at play include genetics, age, race and ethnicity, diet, physical activity, hormones, and social factors.
You will lose up to 10 pounds (4.5 kgs) if you consume 800 calories and exercise regularly. Make sure your doctor or nutritionist is aware of your diet pattern.
Physical Inactivity: Lack of exercise or physical activity can cause fat gain and slow our metabolism. Once we start exercising, our heart rate increases and blood pumps through our muscles. When you are working out, your muscles are burning calories and your metabolism increases.
The most obvious signs of a damaged, slow metabolism are weight gain, weight loss plateaus, and difficulty losing weight — even on a low-calorie diet with exercise. Many other signs and symptoms of a slow metabolism mirror those of hypothyroidism.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.
Regular exercise increases muscle mass and teaches the body to burn kilojoules at a faster rate, even when at rest. Drugs – like caffeine or nicotine, can increase the BMR. Dietary deficiencies – for example, a diet low in iodine reduces thyroid function and slows the metabolism.
For years, the assumption has been that your metabolism is slowing as you age. But a study that included 6,500 people from 29 countries shows that metabolism for both men and women really doesn't significantly drop off until you reach the age of 60.
With low levels of thyroid hormones in the blood, you will likely experience slowed metabolism and likely put on weight. Vitamin D deficiency, however, is often ignored as a potential cause of tiredness and fatigue, which can leave you without energy and motivation to work out or stick to your weight loss routine.
Summary. For many people, the term metabolism really means metabolic rate — the speed at which your body burns calories to keep its basic functions running. Your metabolic rate does change during your early life, but it plateaus between the ages of 20 and 60, and only decreases by around 1% per year after that.
Effective At Weight Loss
If you need to shed pounds fast and don't expect the long-term result, the 1000 calorie meal plan may help you with that. As mentioned at the beginning of this article, this diet can help you lose 2-3 pounds (1-1.5 kg) a week, which is quite fast.
