Here's how the body reacts to one-off overeating – new research

How much humans can eat

One study asked healthy participants to eat pizza until they felt full. Then on a separate day to eat pizza until they couldn't anymore. They ate twice as much as on the first take, suggesting that when you feel full, you're probably only half full.

Blood samples were also taken at regular intervals to see how the body was coping. Despite eating twice as much food, there was only a small increase in blood sugar and blood fat levels.

How much humans can eat

One study asked healthy participants to eat pizza until they felt full. Then on a separate day to eat pizza until they couldn't anymore. They ate twice as much as on the first take, suggesting that when you feel full, you're probably only half full.

Blood samples were also taken at regular intervals to see how the body was coping. Despite eating twice as much food, there was only a small increase in blood sugar and blood fat levels.

The effect of overeating on the body

  • Studies revealed that in physically active and healthy people, the body is able to control the sugar and fat in the blood after a big meal by working a bit harder than usual to regulate metabolism.
  • Hormones released from the gut and pancreas help the body to regulate blood sugar levels.
  • After participants ate past the point of feeling comfortably full, they had little desire to eat anything even four hours after the meal.
  • The also felt sleepier and less energetic after eating too much.

Long-term overeating

Healthy humans rely on the body's ability to work harder in times of need.

However, when we repeatedly eat too many calories at each meal, metabolic syndrome - a combination of high blood pressure, diabetes, and obesity - will result. Over time, the body will become unable to react to these situations.

Drink More Cold Water

Drinking water may speed up your metabolism for about an hour. This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it.

Drinking water can also help you fill up and help you eat less, especially if you drink it half an hour before you eat.

Do a High-Intensity Workout

High-intensity interval training (HIIT) involves short, intense bursts of activity and help you burn more fat by increasing your metabolic rate.

"Hot" Workouts

They won't really help you lose weight. Research suggests regularly sleeping in colder temperatures may be optimal for weight loss as they stimulate the production of brown fat, the "good" fat. Brown fat keeps us warm by burning through "bad" fat stores.

Turn down the heat at night. You'll trim your belly and your heating bills.

Tongue-Scorching Peppers

Hot sauce can boost your metabolism. But research suggests that more-palatable, mild peppers may have the same calorie-burning potential.

Pack your salads and stir-fry with sweet peppers-including bell peppers, pimentos, rellenos, and sweet banana peppers. They're just as effective as the hot stuff.

How The Body Uses Calories
  • Basal metabolism is the energy our body needs to keep our cells working and accounts for 65-80% of most adults' caloric consumption.
  • The thermic effect of food is the energy our body uses to process food and accounts for 10% of most adults' caloric consumption.
  • Physical activity accounts for 10 - 30 % of most people’s caloric consumption .
Controlling Your Own Weight

Not everyone overeats and becomes overweight, and not everyone who becomes overweight or obese develops illnesses like diabetes or heart disease. 

There was never a special diet, exercise regimen, or supplement that worked universally to control weight. Through trial and error, we have to discover habits and routines we can stick with that help us eat less and move more.

Metabolic Rate And Weight

It is a common belief that slim people have a higher metabolism and overweight people have a slower metabolism. But, this is rarely the case.

Overweight is in most cases a result of a lifestyle in which one group generally consumes more calories than they need. There isn’t much we can do to significantly change our resting metabolic rate, but long-term strategies, such as increasing muscle mass, may eventually have an effect.

Anabolism

Anabolism is a succession of chemical reactions that build molecules from smaller components and usually require energy. Anabolism allows the body to grow new cells and maintain all the tissues.

When weight loss slows down

When dieting to lose weight, there are two primary reasons why weight loss slows down over time:

  • Calorie expenditure decreases with weight loss because fewer calories are needed to maintain and move a lighter body.
  • Weight loss increases the appetite. The hormone leptin tells our brain how much fat is stored in our body. When we lose body fat, leptin decreases and increases our appetite.

Changes in calorie expenditure and the effect of body fat stores on appetite will stabilize body weight in the long run. However, it is hardly noticeable in the short term.

Prevent overeating

We get hungry when our stomach tells our brain that it's nearly empty. But signals from our stomach can leave us vulnerable to overeating.

Fullness is determined partly by the fat, carbohydrate, and protein content of the meal, and partly by the overall amount. If a meal contains more fiber, it's more filling. That is why it is hard to overeat on foods such as fruits and vegetables.

Limit Your Eating

Several new studies are claiming that restricting our meals, and not eating post-afternoon, has some remarkable benefits.

Limiting our eating has produced miraculous results in these studies, where insulin levels of the body along with insulin resistance, dropped due to the semi-fasting.

Last Meal At 2 pm

Eating in your last meal of the day in the afternoon results in a 16 to 18 hour fast, which can significantly boost your health, according to research.

The tests also show that it is not hard to fast in the evening, and green tea, coffee etc. can help as a fasting aid.

Intermittent fasting

Intermittent fasting ranges from eating a few calories all day every other day or several times a week to fasti...

A metabolic shift

It can take 10 to 12 hours to use up calories in the liver before your body changes over to use the stored fat.

After meals, glucose is used for energy, while fat is stored in fat tissue. During fasts, once glucose is depleted, stored fat is broken down and used for energy.

The easiest way to lose weight

To lose weight, strive for sixteen calorie-free hours. Stop eating by 8 pm, and eat again at noon the next day. Results can take up to four weeks to notice.

Intermittent dieters should eat healthy foods, including whole grains and healthy fats and protein. They should limit saturated fats and avoid sugar and refined carbohydrates. Be sure to stay well-hydrated.

Fast facts on ketosis
  • Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose.
  • Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid.
  • In small amounts, ketones serve to indicate that the body is breaking down fat, but high levels of ketones can poison the body, leading to a process called ketoacidosis, a serious condition that can prove fatal.
  • People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma.
  • Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores.
The ketogenic diet
The diet itself can be regarded as a high-fat diet, with around 75 % of calories derived from fats,  20 % from proteins and 5 % from carbohydrates.

Adhering to the ketogenic diet can lead to short-term weight loss, consuming fewer calories without feeling hungry while following the diet.

Ketosis

... is a natural state of the metabolic process. When a person has reached ketosis, their body is burning stored fat instead of glucose.

7 tips to get into ketosis
  • Increase physical activity
  • Reduce carbohydrate intake significantly
  • Fast for short periods
  • Increase healthful fat intake
  • Test ketone levels
  • Maintain a high protein intake
  • Consume more coconut oil as this may help to increase ketone levels.
Ketosis in summary
  • Ketosis is a natural state for the body to be in from time to time. When it occurs, the body burns its fat reserves as energy.
  • Maintaining a state of ketosis for short periods involves minimal risk. However, people with type 1 diabetes should avoid ketosis due to an increased risk of complications.
  • People should also avoid being in ketosis long-term, as they may experience fatigue and nutritional deficiencies.
  • Making several dietary and lifestyle changes can help a person get into ketosis faster.
