Gaining muscle and not losing fat often comes down to diet. It's possible that you're eating too much and may need to decrease your calories slightly. You'll also need to analyze your workouts and overall daily activity levels and consider adding in more calorie-burning activities to boost your fat loss efforts.
Muscle is denser than fat.
While one pound of fat weighs the same as one pound of muscle, muscle occupies about 18 percent less space. In addition, muscle burns calories while fat stores them. So, if your weight isn't decreasing but your clothes are starting to fit more loosely, you may be building muscle.
If you're losing weight but your body fat percentage is staying the same, it's probably a sign you're losing muscle. "Your body won't shape the way you want. You'll notice shrinking circumferences, but the pinch-able fat is the same," says Dr. Nadolsky.
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.
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. Closely tracking your weight during this window can be confusing—your clothes may feel looser while the number on the scale stays the same or even goes up a few pounds.
Elevated cortisol levels drive hunger and cravings for tasty junk foods, which is why chronically elevated levels can lead to weight gain or prevent weight loss. Smart ways to prevent stress-related weight gain include: cutting down on training sessions. giving your body time to recuperate between workouts.
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.
We've all heard the term 'fat-burning', but how does it really happen in the body? Fat cells in the body release a hormone that signals to the brain that there is enough energy stored. This triggers your body to burn energy stored as fat. It also affects your desire to eat.
At the most basic level, not reaching your weight loss goal can occur when calorie intake is equal to or higher than calorie use. Try strategies such as mindful eating, keeping a food diary, eating more protein, and doing strength exercises.
While no specific foods can cause us to be kicked out of fat burn, consuming too many carbs will. Carbs in the form of sugar, preservatives, and fillers are hidden in many foods we wouldn't expect, making it all the more challenging to stay in fat burn for long if we aren't careful.
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. Your total daily energy expenditure also depends on your weight.
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.
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.
Leptin. What it is: Leptin is derived from the Greek word for “thin,” because rising levels of this hormone signal the body to shed body fat. Leptin also helps regulate blood sugar, blood pressure, fertility and more.
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.
People with an endomorph body type tend to have a slow metabolism, making it easier for them to gain weight and harder for them to lose it. This also stunts muscle growth. However, following a specific diet and exercise plan can often help people with endomorphic bodies meet and maintain their health goals.
Those extra pounds were packed on in early adulthood: The average American gained about 17.6 pounds from their mid-20s to mid-30s, the study found. Meanwhile, the average person gained about 14.3 pounds between their 30s and 40s, 9.5 pounds between their 40s and 50s, and 4.6 pounds between their 50s and 60s.
The bottom line
Study findings suggest that we burn calories the fastest in our first year of life, steady down to our “normal” rate by our 20s and stay that way into our 50s.
New study says decline begins in our 50s
Researchers with Duke University's School of Medicine suggest that physical decline begins in the decade of the 50s and worsens as we age, especially for those who don't exercise.
