Do You Have to Sweat When Exercising to Lose Weight?

Losing weight requires commitment, diet and exercise -- but not necessarily sweating. Sweating occurs naturally when your body temperature rises, this much is true, and exercising does cause your body temperature to rise. However, other factors determine if and how much you sweat. Even if you push yourself through a hard, calorie-burning workout, your body may remain dry and sweat free.

Sweating

Factors including air temperature and genetics play a role in how much you sweat when exercising. If you exercise in a colder room, your internal body temperature will rise, but it will take a while to produce sweat. Although you are not sweating, you're still burning calories just as you would in the heat and humidity, according to NBC News. Every person sweats differently. Look around next time you are at the gym. You will see some people covered in sweat and others perfectly dry. Either way, they are all burning calories and on the road to losing weight.

Sweat and Weight Loss

Sweating contributes to the loss of water weight, which technically is weight loss. Unfortunately, the majority of the weight lost from sweating comes back after you drink water to rehydrate your body. This temporary weight loss comes along with the loss of weight from the calories used throughout your day. Your body constantly burns calories, even when you sleep, watch TV or go to the restroom. As you might have noticed, these activities do not require sweating.

Adipocytes

When you go to the buffet and engorge yourself on favorite foods until you cannot walk, you ingest many calories. Your body converts unneeded buffet calories to triglycerides, which are stored in your fat cells or adipocytes. As the adipocytes absorb fat, they increase in diameter, making you gain weight and become fatter. Stopping this process requires avoiding the buffet line and cutting the amount of calories you eat to the point that your body starts burning triglycerides rather than storing them.

Calories and Fat

How many calories your body requires varies depending on your activity level, physical fitness, body weight and gender. To determine if you are eating too many calories, eat normally while watching your weight. If your weight increases, you are eating too much. Decrease your intake of food until your weight remains unchanged. Write down the number of calories you eat every day as you change your diet. Lower your calories slowly until you begin to lose weight and forget about the amount you sweat. A variety of calorie calculators are also available online if you'd like to estimate how many calories your body needs daily to maintain your current weight.
