When the supply of energy—the number of calories consumed in foods—exceeds the body's immediate needs, the body stores the excess energy. Most excess energy is stored as fat. Some is stored as carbohydrates, usually in the liver and muscles. As a result, weight is gained.
Repeatedly consuming more calories than you burn can cause you to become overweight, and eventually, obese. This, in turn, can increase your risk of cancer and other chronic health problems, such as diabetes and hypertension.
If you eat more calories than you burn, you gain weight. And if you eat fewer calories and burn more calories through physical activity, you lose weight. In the past, research found about 3,500 calories of energy equaled about 1 pound (0.45 kilogram) of fat.
One of the most evident effects of excess calorie intake among young people is weight gain. Obesity rates among youth have reached alarming levels, with millions of young individuals worldwide struggling with this condition. The surplus calories are stored as fat, leading to an increase in body weight.
When you eat too many calories each day, the excess calories (or energy) have to go somewhere. Your body stores these calories by turning them into body fat.
What happens when we take in more energy-providing nutrients than we need? In other words, what happens to those excess calories when we over-eat? As we know from personal experience, the excess is stored as body fat.
The Science of Fat Loss
Think of it like a balloon losing air—it deflates, but doesn't disappear immediately. Over time, your body adjusts, but the jiggly feeling can be a temporary step along the way.
So if you could eat 50,000 calories in one day… you'd probably gain weight! 2000 calories is the recommended daily intake! So you'd be 48,000 plus calories or about 13.71 lbs.
Many factors go into determining your calorie needs. Your age, weight, sex recorded at birth, height and activity level all play a role. According to dietary guidelines in the United States, adults 21 years old and older should consume anywhere between 1,600 and 3,000 calories per day.
Dr. David Katz, reports in "O, the Oprah Magazine," that the body begins to store consumed calories as fat within four to eight hours from the beginning of the meal. As you consume these calories, the body automatically stores the first 1,000 calories within the liver and muscles for immediate energy reserves.
When it comes to balancing food eaten with activity, there's a simple equation: energy in = energy out (in other words, calories eaten = calories burned). So, yes, it is possible to burn off food calorie for calorie with exercise.
As your body metabolizes fat, fatty acid molecules are released into the bloodstream and travel to the heart, lungs, and muscles, which break them apart and use the energy stored in their chemical bonds. The pounds you shed are essentially the byproducts of that process.
You gain weight when you eat more calories than you burn — or burn fewer calories than you eat. Some people seem to lose weight more quickly and more easily than others. But everyone loses weight by burning more calories than are eaten.
you're likely to put on weight if you eat and drink more calories than you use. This is because your body stores the extra energy as fat. you're likely to lose weight if you eat and drink fewer calories than you use. This is because your body uses its stored fat for energy.
Consuming at least 1,200 calories per day has often been touted as the minimum for basic bodily functions and to stay out of starvation mode, but the amount is actually too low. A healthy amount of calories for adult women ranges from 1,800 to 2,400 calories per day and for men it's 2,000 to 3,200 calories per day.
The calories in an egg will vary depending on the size and how it is prepared. However, on average a single medium-sized egg will contain around 66 calories, an average small egg will contain around 55 calories and an average large egg around 80 calories.
The current record holder is Erik The Electric, who's 30,000 calorie cheat day was incredible to watch. If you haven't seen it yet, I recommend you watch it. There are no limitations on what can be consumed.
The true value of actual weight gain is surprisingly low. A small study on 15 healthy young males eating 6,000 calories for one day revealed a total weight gain of 1.87 pounds. This calorie level is extremely difficult to do regularly. Remember, some of this weight gain would be water weight and some undigested food.
If you took the most calorically dense food you could find, perhaps olive oil to avoid saturated fats, you would need to consume 3.3 gallons to get your 100,000 calories. Assuming this was possible, you would overwhelm the lipid uptake capacity of your intestines and most of it would just pass straight through you.
As you add muscle mass and lose fat, the reading on your bathroom scale may not change much, but your pants will be looser. That's a better mark of progress. Measured around, your waistline should be less than 35 inches if you're a woman or less than 40 inches if you're a man to reduce heart and diabetes risks.
The “whoosh effect” is a term for the noticeable weight loss that some people report while following low carb diets such as a keto diet. Some people believe that the whoosh effect happens when fat cells lose fat and fill with water. Researchers have not scientifically proven the whoosh effect, however.
