What happens when you diet and exercise

What happens to body fat when you shed pounds — do you sweat it out, pee it out or breathe it out? The answer is yes, yes and yes. Advertising Policy Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services. Policy How on earth does this happen? “It helps to understand that our bodies are designed to store excess energy in fat cells,” says endocrinologist Bartolome Burguera, MD, PhD. If you’re carrying extra pounds, it means you’re taking in more energy (calories are units of energy) than you’re using. “The extra energy is stored in adipose tissue all around your body in the form of triglycerides,” says Dr. Burguera. Smaller amounts of energy are stored in your liver and muscles as glycogen.

How does your body use energy? In more ways than you’d think:

When you’re resting. Your heart needs energy to pump, your lungs to breathe and your brain to think. (That’s your basal metabolism.) Your heart needs energy to pump, your lungs to breathe and your brain to think. (That’s your basal metabolism.) When you’re active. Your muscles need energy whether you’re only getting up from a chair or running a marathon. Your muscles need energy whether you’re only getting up from a chair or running a marathon. When you’re eating. Your digestive system needs energy to break down and store food.

What happens to body fat when you diet?

When you diet, you take in fewer calories than your body needs. Because of this deficit, your body turns to fat reserves for energy.

The byproducts of fat metabolism leave your body:

As water, through your skin (when you sweat) and your kidneys (when you urinate).

As carbon dioxide, through your lungs (when you breathe out).

“Meanwhile, fat breakdown liberates energy for biological functions and physical activity,” he says. “It also generates heat, which keeps body temperatures normal.”

What happens to body fat when you exercise?

Your muscles first burn through stored glycogen for energy. “After about 30 to 60 minutes of aerobic exercise, your body starts burning mainly fat,” says Dr. Burguera. (If you’re exercising moderately, this takes about an hour.) Experts recommend at least 30 minutes of cardio two to three times a week. They also recommend weightlifting and resistance training. Increasing muscle mass may help you burn more calories and raise your basic metabolic rate. Exercise also increases your respiratory rate, so more CO2 leaves your body when you work out.

About exercise and weight loss

“Exercise is key to weight loss and to maintaining that weight loss,” says Dr. Burguera. But it may take time to move the number on your scale, so be patient. Everyone’s response to exercise varies: Some people lose weight, others maintain it, and a few may even gain a few pounds. “Generally, however, people who successfully lose weight and keep it off tend to be physically active — up to an hour per day,” he says. “Engaging in some form of exercise three times per week is highly recommended.”

webmd.com - Can You Lose Fat in Your Face? - WebMD

Many people gain weight. It’s common to want to lose weight in one particular area of your body – like your face. While you can’t reduce fat in one area alone, you can take steps to slim your face and lose weight overall .

Losing Fat in One Body Part

Some people believe that they can lose fat in a single area of their body. This concept is also called spot reduction. There are many exercises that target specific body parts, like your stomach or thighs. While exercises do help build specific muscles, they primarily improve your definition after weight loss. Exercises, including strength training, help you burn fat from your entire body.‌ If you want to lose fat in your face, focus on healthy weight loss goals to better your overall health. You may be tempted to follow an exercise regimen or diet that boasts desired results, but don’t be fooled. Spot reduction is a myth. When you lose weight in general, you will also slim your face.‌ Each person loses weight differently. Don’t feel discouraged if you don’t see a difference in your face right away. Be patient and persistent in pursuing your weight loss goals. If you do strength training, the scale may not move as much as you want. This happens because your body is adding weight in lean muscle. You will still see a difference in your face and overall appearance with time.
