Your hormones play an important role in these processes. Different hormones in the body are associated with either anabolism and catabolism. Any disruption to your hormones, like thyroid conditions , may also affect these processes and your overall metabolism. For example, a small study on bodybuilders examined their hormonal anabolic-catabolic balance as they prepared for competition. Some of the men continued training and eating as usual, while others were energy-restricted to reduce their body fat.
The energy-restricted group saw significant decreases in their body fat and muscle mass compared to the control. Their insulin and growth hormone levels also decreased throughout the duration of the study. Testosterone levels, too, decreased between 11 and 5 weeks before competition.
The researchers concluded that the bodybuilders may need to employ other nutritional strategies to prevent a catabolic breakdown effect before competition. Since anabolism and catabolism are parts of your metabolism, these processes affect your body weight.
You may be able to manipulate your body weight by understanding these processes and your overall metabolism. Both the anabolic and catabolic process lead to fat loss over time. With regard to your weight on the bathroom scale as a benchmark, however, things can get a bit tricky. You can think of these processes as an equation to predict whether or not you may lose or gain weight. Take catabolism how much energy your body produces and subtract anabolism how much energy your body uses.
If you produce more than you use, you may pack on pounds as the energy gets stored away as fat. If you use more than you produce, the opposite may happen.
There are exceptions, of course, especially if you have underlying medical conditions that affect your hormones. Working your body in different ways can produce different results. Cardio and strength training are each associated with different metabolic processes. Catabolic exercises are aerobic, or cardio, exercises. According to the American College of Sports Medicine , aim to get at least the following amounts of aerobic exercise each week:. This is usually broken down into three to five days of training.
If you have a history of health conditions, check in with your doctor to get the OK before starting this regimen. Your heart rate, blood pressure, and respiration all rise during catabolic exercise. The body breaks down glycogen during your sweat sessions to use as fuel. As a result, catabolic exercises may help you build a healthy heart and lungs. But they may also cause you to lose body mass, both muscle and fat. It effectively breaks down muscle over time.
Some of this muscle may be rebuilt during sleep or rest of eight hours or more through spontaneous anabolic processes.
It can decrease your muscle mass and even compromise your overall health. Preventing catabolism is all about keeping good balance between your nutrition, training, and recovery. Updated February 04, Key Takeaways: Anabolism and Catabolism Anabolism and catabolism are the two broad classes of biochemical reactions that make up metabolism. Anabolism is the synthesis of complex molecules from simpler ones.
These chemical reactions require energy. Catabolism is the breakdown of complex molecules into simpler ones. These reactions release energy. Anabolic and catabolic pathways typically work together, with the energy from catabolism providing the energy for anabolism. Featured Video. Cite this Article Format. Helmenstine, Anne Marie, Ph.

Catabolism provides the energy our bodies need for physical activity, from cellular processes to body movements. Catabolic reactions in the cells break down polymers long chains of molecules into their monomers single units.
For example:. When we eat, our body breaks down nutrients — this releases energy, which is stored in molecules of adenosine triphosphate ATP in the body. The energy stored in ATP is the fuel for anabolic reactions.
Catabolism creates the energy that anabolism consumes for synthesizing hormones, enzymes, sugars, and other substances for cell growth, reproduction, and tissue repair. Body weight is a result of catabolism minus anabolism — the amount of energy we release into our bodies catabolism minus the amount of energy our bodies use up anabolism.
The excess energy is stored either as fat or glycogen in the muscles and liver. Glycogen is the main storage form of glucose in the body. One gram of fat produces 9 calories , compared with 4 calories from a gram of protein or carbohydrate. Although becoming overweight is a result of the body storing excess energy as fat, sometimes, hormonal problems or an underlying medical condition may affect metabolism.
If someone is very overweight or obese, it may be advisable to have a medical evaluation to determine whether a medical condition is affecting body weight. BMI is an evidenced-based way to calculate ideal body weight ranges for age and height. A larger body mass requires more calories. People with more muscle in relation to fat will require more calories than individuals who weigh the same but have less muscle in relation to fat. Therefore, people with a higher muscle-fat ratio have a higher basal metabolic rate than people with a lower muscle-fat ratio, if their weight is the same.
As people age, several factors emerge that result in a lower calorie requirement. Muscle mass drops, resulting in a higher fat-muscle ratio. After determining calorie requirements and confirming that there is no underlying condition contributing to weight gain, focusing on three crucial factors is the best approach; these are:.
Lack of sleep can contribute to a disturbance in neuroendocrine control of appetite.
