What is fast metabolism?

Fast or high metabolism refers to the tendency of your body to burn more calories in a given amount of time (even while at rest) compared to the metabolism of other people.

You might be surprised to find that between 10 and 20 percent of the energy your body consumes each day is used during routine daily activities like walking, while up to 80 percent of that energy is used while it is at rest. Your body uses about 5 to 10 percent of its total energy for digesting.

What are the signs of fast metabolism?

Your metabolic rate can be influenced by a range of variables, including sex, weight, hormone function, age, and levels of physical activity. Generally speaking, your metabolism is faster if your body mass is lean.

Some signs that you could have a fast metabolism include:

  • Despite eating regularly, you struggle to gain weight or maintain your current weight.
  • Your body temperature is high, even while you are resting.
  • Even after eating a meal or a snack, you frequently feel hungry or have an insatiable desire.
  • You miss your period or have an irregular menstrual cycle while not being pregnant.
  • You may need to urinate frequently because your body’s processing speed has increased.

Can I Gain Weight with a Fast Metabolism?

Some people do, in fact, burn more calories. They could be bigger, more active, or eat foods that convert more energy into heat (such as protein). However, many slim guys are “hardgainers.” We have adaptive metabolisms in addition to our fast metabolisms. Our attempts to gain weight fail when we eat more food and our bodies burn more calories too. This phenomenon is called non-exercise activity thermogenesis (NEAT), and it may be really annoying.

The good news is that there are limits to how many calories you can burn. You can increase your calorie intake when your metabolism adjusts by burning more calories. If you aren’t gaining at least a little weight every two weeks, add 200 calories to your diet. If your weight loss plateaus again, increase your calorie intake by 200. That is how someone with a fast metabolism might acquire weight.

How to gain weight with a fast metabolism?

There are some tips that can help you gain weight quickly while also adding muscle. Males and females have no significant differences in gaining weight. You can increase your weight by doing the following things:

  • Consuming meals high in energy
  • Eating 5 to 8 smaller meals throughout the day
  • Avoid drinking water before meals
  • Using a lot of carbs and proteins
  • Using meal supplements for weight gain
  • Including complex exercises in your routines
  • Having enough sleep
  • Add cream to your coffee
  • Lifting heavy-weight objects

Don’t forget to be mindful not to consume more than 500 calories if you decide to eat more. A weight gain of one pound per week is ideal. It should not be more than that.


Find healthy ways to slow down your metabolism if you’re attempting to gain weight and your fast metabolism is getting in the way. Consult a professional, reliable healthcare specialist or a doctor before making any sudden dietary or lifestyle changes. The specialist checks your BMI, body composition, muscle mass, body shape and some other health indicators with an advanced instrument such as a 3D body scanner and presents you with the most helpful suggestions.

The body may react unexpectedly to any quick changes since it might be sensitive to them. Your health may be impacted if you change your food and other routines suddenly, increase or decrease scheduled physical activity, sleep fewer hours at night, or change your nutrition. Make changes gradually and pay attention to any outcomes to gain weight safely.
