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.
When the calories you burn equal the calories you eat, you reach a plateau. To lose more weight, you need to either increase your physical activity or decrease the calories you eat. Using the same approach that worked at first may maintain your weight loss, but it won't lead to more weight loss.
Significant weight loss and muscle gains will take approximately eight weeks to see, however, even though you're not seeing muscle definition, the benefits going on in your body and mind are considerable. “Your clothes will fit better, your posture will be better and you'll walk taller,” Sharp says.
Muscle mass is denser than fat mass and you will undoubtedly gain weight from lean muscle gains. While your clothes may feel looser, the scale may tell you otherwise. This is a win! You're working a well-rounded program that includes both strength and conditioning and now you're reaping the reward.
“When you start exercising, your muscles start gobbling up fuel called glycogen,” says Krista Scott-Dixon, Ph. D., Director, Headspace Adjustment Bureau, Precision Nutrition. Since glycogen stores water, you could gain up to 10 pounds in water weight alone, says Scott-Dixon.
Water Retention
As individuals start to actively lift weights and engage in exercise, stress is added to their muscle fibers. This results in micro-tears and some minor inflammation, which can lead to added water retention in the body.
You've Gained Muscle Mass
If you're exercising regularly and doing a mix of cardio and strength training, it's very likely your body composition (ratio of muscle to fat) is changing for the better. If you're gaining muscle while losing fat, the scale may not show any weight change.
As a general goal, aim for at least 30 minutes of moderate physical activity every day. If you want to lose weight, maintain weight loss or meet specific fitness goals, you may need to exercise more. Reducing sitting time is important, too. The more hours you sit each day, the higher your risk of metabolic problems.
If you're consuming too few calories your body essentially goes into starvation mode and receives the message that it needs to protect itself. This means holding onto weight for protection's sake. The body perceives reduced calorie intake as a stressor.
As you work out, you are building lean muscle which weighs exactly the same as fat but is leaner. if your clothes are looser but the scale is the same, this is because of the lean muscle you have built.
Unhealthy eating is the biggest driver of big bellies. Too many starchy carbohydrates and bad fats are a recipe for that midsection to expand. Instead, get plenty of veggies, choose lean proteins, and stay away from fats from red meats. Choose healthier fats in things like fish, nuts, and avocados.
While seeing results from working out heavily depends on the person and their current level of fitness, "My [clients] generally see initial changes within four to six weeks, and actual results within eight to 12 weeks," Wilson explains.
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.
Body-weight loss is usually noticed around the belly, waistline, and thighs first. This is because your body stores fat in different locations. For instance, men hold more fat around their belly, while women store it on their thighs and hips. Weight loss gradually starts with a reduction in belly size.
A new exercise regimen puts stress on your muscle fibers. This causes small micro tears, also known as micro trauma, and some inflammation. Those two conditions in your muscle fibers are the reason you may gain some weight.
You'd think that going on a strict diet and exercise regimen would help you drop pounds quickly, but most people actually gain weight at first. If this has happened to you, don't give up on your goals just yet.
Weight gain
Exercising too much without resting enough in between can lead to low testosterone levels and high levels of cortisol, the stress hormone. These hormonal changes are often associated with loss of muscle tissue, weight gain, and excess belly fat.
You're putting your whole heart and soul into the fitness regimen, going to the gym five days each week. You should be able to notice visible changes after about two weeks of training 5 days a week.
Strength training specifically leads to gain lean muscle gain. These are fat-free tissues that are highly metabolic, allowing more caloric burns than any other tissue in the body. Essentially, this is why strength training works best: it loses fat while maintaining muscles that burn calories.
According to Noah Abbott, a CrossFit coach in Brooklyn, prolonged, steady-rate cardio can deplete our body's Triiodothyronine, or T3 hormone. This hormone is responsible for metabolism, and a depletion of this hormone can cause the body to go into a mode where it stores and gains more fat than usual.
