There are many reasons to build muscle, including preventing injury, improving bone density, and lowering the risk of type 2 diabetes. But does adding muscle increase your basal metabolic rate (BMR) – the calories you burn just by being alive? The answer is yes, but not by a huge amount. Research suggests that each pound of muscle burns an extra 6 calories a day. So, if you weigh 160 pounds and add 30 pounds of muscle, you'll burn about 180 extra calories a day. This means that while building muscle can slightly increase your metabolism, it's not a significant enough change to rely on for weight loss.

What You'll Learn
Strength training increases basal metabolic rate
Strength training is a popular way to build muscle and boost metabolism. Research shows that strength training increases basal metabolic rate (BMR), which is the number of calories burned at rest.
One study found that basal metabolic rate spiked by 4.2% 16 hours after a strength-training session lasting an hour and 40 minutes. This is equivalent to burning 60 extra calories. However, Excess Post-Exercise Oxygen Consumption (EPOC) is not a permanent boost and may last from 12 hours to a few days, depending on the individual and the workout. While strength training can increase BMR, it may not drastically affect daily calorie burn.
The impact of strength training on BMR also depends on various factors, including sex, genetics, age, and the size of internal organs. For example, research shows that strength training increases resting metabolic rate and norepinephrine levels in healthy 50- to 65-year-old men. Additionally, the type of exercise, weight used, number of reps and sets, rest time, and total workout duration all influence the boost in BMR from strength training.
While adding muscle mass through strength training can increase BMR, the effect may be small. Research suggests that each pound of muscle burns approximately 6 extra calories per day, which may not significantly impact daily calorie burn. However, building muscle mass offers other benefits, such as improved bone density, injury prevention, and a reduced risk of diseases like type 2 diabetes.

Building muscle can help prevent diabetes
For those with type 2 diabetes, strength training can help with blood sugar control. Simple moves done regularly can prompt the muscles to absorb more glucose and burn more calories. Additionally, building muscle can help lower the risk of type 2 diabetes.
To build muscle, one can use hand-held weights, resistance bands, or even their own body weight. It is recommended to consume about 1 gram of protein per pound of body weight, which is roughly the maximum amount the body can use in a day. Protein shakes are effective for improving strength, and drinking a shake with amino acids and carbohydrates before a workout increases protein synthesis more than drinking the same shake after training.
However, it is important to note that weight-gain powders, which are high in protein, can also be extremely high in calories, carbohydrates, and sugar, which may not be ideal for those with type 2 diabetes aiming for weight loss. Additionally, those taking diabetes medications may need to adjust their doses before and after exercise, as working out can affect blood sugar levels. It is always recommended to consult a doctor before starting any new exercise routine.

Resistance training is important for building muscle
Adding muscle does increase your basal metabolic rate (BMR), or the calories you burn just to live, but the effect is small. Each pound of muscle burns about 6 extra calories a day, so even if you gain several pounds of muscle, the metabolic effect is still quite minimal.
Resistance training is a great way to build muscle and is important for a variety of reasons. It involves using one or more muscle groups to perform a specific task, such as lifting a weight or squatting, and can be done with free weights, weight machines, resistance bands, suspension equipment, or just your own body weight.
To build muscle through resistance training, you need to challenge your muscles. This means selecting a weight that allows you to perform 8-15 reps for 1-3 sets while maintaining proper form. If you can easily perform 15 or more reps, you should increase the weight. It's also important to vary your workouts and the number of repetitions and sets performed to maintain your strength gains.
Resistance training has many benefits beyond building muscle, including improved joint function, bone density, tendon and ligament strength, flexibility, balance, and posture. It can also help with weight management, as you gain muscle, your body burns more kilojoules when at rest. Additionally, resistance training can help prevent or control chronic conditions such as diabetes, heart disease, arthritis, back pain, depression, and obesity.

Cardio burns more calories than resistance training
Cardio, or cardiovascular exercise, is a form of aerobic activity that increases breathing rate, burns calories quickly, and improves overall endurance. It burns more calories per session than weight training for the same effort and duration. For example, a 154-pound person will burn about 145 calories in 30 minutes of moderate-paced bicycling, whereas they would burn around 110 calories if they lifted weights for the same duration.
However, it is important to note that the number of calories burned during exercise depends on body size, exercise intensity, and other factors such as genetics, hormones, sleep, and diet. While cardio may burn more calories in a single session, weight training can have a greater impact on metabolism and fat burning in the long term. This is because weight training builds muscle, which increases basal metabolic rate (BMR) and leads to higher EPOC levels, resulting in more significant muscle breakdown and continued calorie burning even after the workout.
Research has shown that each pound of muscle burns approximately 6 extra calories per day, which may not seem significant, but it can add up over time, especially with consistent weight training. Additionally, muscle is more metabolically active than fat, so building muscle can help keep fat off in the long run.
High-intensity interval training (HIIT) is another option that can burn more calories in a shorter period of time than traditional cardio or weight training. It involves short bursts of intense exercise alternated with low-intensity recovery periods.
In conclusion, while cardio burns more calories per session, weight training and HIIT can have more promising long-term results due to their impact on metabolism and muscle-building potential.

Muscle mass doesn't significantly increase metabolism
The relationship between muscle and metabolism has been a topic of debate, with some believing that building more muscle significantly increases metabolic rate and calorie burn, while others argue that muscle does not burn enough calories to have a substantial impact on daily calorie burn.
Research suggests that every pound of muscle burns approximately 6 calories per day. Comparatively, a pound of fat burns around 2 calories per day. This suggests that while increasing muscle mass does lead to a higher metabolism, the effect is minimal and may not significantly contribute to weight loss or increased calorie burn. For instance, gaining 30 pounds of muscle would result in an extra 180 calories burned per day, which is a negligible amount.
Additionally, the impact of strength training on metabolism may be overstated. While strength training can lead to a temporary increase in metabolism, known as EPOC, this effect is not permanent and typically lasts for 12 hours to a few days. The overall impact of EPOC on calorie burn is also relatively small compared to the calories burned during the actual exercise.
It is important to note that building muscle and increasing strength have numerous other health benefits beyond a potential increase in metabolism. These benefits include improved bone density, lower risk of type 2 diabetes, and improved glucose metabolism. However, if the primary goal is to increase metabolism and calorie burn, focusing solely on building muscle mass may not be the most effective strategy.
