Hormones A shift in your hormones can put the brakes on your body's energy use. That can make you tired. Some conditions, like an underactive or overactive thyroid and diabetes, are hormonal diseases that affect your metabolism. Stress also releases hormones that can trigger a slow-down.
Behaviour and obesity hormones
Various studies have shown that a person's blood leptin level drops after a low-kilojoule diet. Lower leptin levels may increase a person's appetite and slow down their metabolism. This may help to explain why crash dieters usually regain their lost weight.
Some of the best natural metabolism boosting supplements for this are caffeine, capsaicin, green coffee bean extract, and green tea extract. Including them in your diet will help you see some benefits, but the greatest effects come from taking metabolism pills such as Leanbean or PhenQ.
Over time, studies have shown that metabolic rate (how fast we burn calories) starts to slow down by 2 to 3 percent each decade, beginning in our 20s. It becomes more noticeable between ages 40 and 60.
But another 120-pound person may have a lot less lean mass and more body fat and therefore a “slow” metabolism. In fact, it is possible to have “normal-weight obesity” – a term used when referring to a person who appears thin but who is not very active and therefore has very little muscle mass, Majumdar explained.
There is such a thing as a slow metabolism. But slow metabolism is rare, and it's usually not what's behind being overweight or obese—that's ultimately a result of interactions among genetics, diet, physical activity, and other factors.
Leptin. Leptin is the hormone that makes you feel full. Unfortunately, those who are already obese sometimes experience problems with leptin not working the way it should. This can make it hard to lose weight, even if you're doing what your doctor tells you, such as eating right and exercising.
Whether you're a man or woman, the hormones testosterone and estrogen play a leading role in your metabolism. Some other hormones that also play a critical role in successful weight management include cortisol, insulin, progesterone, and thyroid hormone triiodothyronine (T3).
Be patient
It may take you some time to increase your metabolism — three months is a reasonable timeframe to expect to see changes. If you are having a hard time losing weight, you might consider having your metabolism tested by a professional nutritionist.
Endomorph Metabolism
Endomorphs have a slow metabolism, so it's easy for them to gain weight (most of which is fat, not muscle). When it comes to fitness and training, a blend of cardio and strength training can help prevent fat gains.
Though some individuals may not appreciate their slow metabolisms, a new study suggests that humans and other primates – who burn 50% fewer calories each day than other mammals – have such long lives because of their curiously slow metabolisms.
Your doctor can see how well your metabolism is working through your BMP. This blood test is like a scorecard for your kidney function, blood sugar levels and more. It can offer clues to help detect various diseases.
Then, between the hours of 10 a.m. to 2 p.m., our digestive functions get stronger and metabolism reaches its peak. Like nature, when the sun is highest in the sky, our body temperature is at its highest point of the day. This is when your body digests foods and burns fuel most efficiently.
Researchers found that metabolism peaks around age 1, when babies burn calories 50 percent faster than adults, and then gradually declines roughly 3 percent a year until around age 20.
B12 works by converting the food we eat into sugar and other types of fuel that keep the body running smoothly. B12 is often associated with weight loss because of its ability to boost metabolism and provide lasting energy.
Your Metabolism Will Slow Down to Store Fat
The more you work out or manage your calorie intake to lose weight, the more your metabolism wants to compensate by slowing down to maintain your current weight, this is called metabolic compensation. It kicks in to preserve and store fat for future energy.
You've gained muscle.
And here's an often overlooked fact: Muscle tissue is more dense than fat tissue. So as you gain more muscle and lose fat, you change your overall body composition, which can result in a higher weight, but a smaller figure and better health.
