Sleep And Weight Fluctuation

Sleep And Weight Fluctuation

Sleeping less has been associated with increased risk of obesity, and addition of body fat, as it affects the overall metabolism of the body, and can also affect our appetite.

Sleep duration is a problem for many adults, as they find sleeping the recommended seven to nine hours a night a challenge, given the hectic lifestyle and social commitments.

Sleep And Weight Fluctuation

Sleeping less has been associated with increased risk of obesity, and addition of body fat, as it affects the overall metabolism of the body, and can also affect our appetite.

Sleep duration is a problem for many adults, as they find sleeping the recommended seven to nine hours a night a challenge, given the hectic lifestyle and social commitments.

More Sleep Means Better Metabolism

  • Various studies point out that sleep influences two appetite hormones, leptin (to decrease appetite) and ghrelin (to stimulate appetite), which is also known as the hunger hormone.
  • Lack of sleep is associated with higher levels of ghrelin and lower levels of leptin, making the person more likely to overeat.

More Sleep And More Exercise

  • Sleep-deprived people crave for and also end up eating more carb-rich foods and sugar.
  • Sleep duration affects the release of insulin in the body, that affects our glucose levels, and prolonged sleep deprivation can lead to obesity and type 2 diabetes.
  • Research shows that exercise prevents the damage done by lack of sleep and also makes one eat less.

To stay healthy, one has to sleep more and also do regular exercise.

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.

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.

The function of ketones

Ketones aren’t just a form of energy, they’re powerful signaling molecules. They regulate the expression of genes and dampen inflammatory processes.
Your body is always producing a very low level of ketones, irrespective of your diet. You start producing more of them when following a diet that’s high in fat and low in carbs.

Getting in ketosis
  • The stricter you restrict carbs (or total calories), the quicker you will be in ketosis.
  • Restricting your carb intake to 20g per day is a good heuristic (loose rule) for entering ketosis. It will generally get you into ketosis within a few days.
  • Fasting gets you into ketosis very quickly.

Detox and its limitations

Detox diets are generally short-term dietary interventions designed to eliminate toxins from your body.

Most Common Ways to Detox

Most detox diets involve at least one of the following:

  • Fasting for 1–3 days.
  • Drinking fresh fruit and vegetable juices, smoothies, water, and tea.
  • Drinking only specific liquids, such as salted water or lemon juice.
  • Eliminating foods high in heavy metals, contaminants, and allergens.
  • Taking supplements or herbs.
  • Avoiding all allergenic foods, then slowly reintroducing them.
  • Using laxatives, colon cleanses, or enemas.
  • Exercising regularly.
  • Completely eliminating alcohol, coffee, cigarettes, and refined sugar.
Which Toxins Are Eliminated

Detox diets rarely identify the specific toxins they aim to remove. The mechanisms by which they work are also unclear.

There is little to no evidence that detox diets remove any toxins from your body.

However, your body can clear itself of most toxins through the liver, feces, urine, and sweat.

Hormones get released when we are hungry: NPY and AgRP from the hypothalamus, and ghrelin from the stomach.

Ghrelin levels tend to be higher in lean individuals and lower in peop...

Feeling sated
About a dozen or so hormones are responsible for making us feel full. 
  • GIP and GLP-1 are responsible for stimulating the production of insulin to regulate the metabolism of carbohydrates.
  • Other hormones are involved in slowing down the movement of food through the stomach.
  • CKK and PYY are vital in reducing the feeling of hunger. (Increased PYY causes a loss of appetite and is particularly high in patients who have a gastric band fitted to reduce the size of the stomach.)
Overeating is a habit

Even though your stomach has a hormonal system for telling your brain it is empty, it can also raise your hunger levels at specific times by learned associations, even if you had a large meal.

If you repeatedly eat chocolate after dinner when you sit on the couch, your body can start to associate sitting on the couch with eating, and you'll experience a craving.

Benefits of a Ketogenic Diet
  • Weight Loss.
  • Keto naturally lowers blood sugar levels due to the type of foods you eat.
  • Mental Focus: Ketones are a great source of fuel for the brain.
  • Increased Energy & Normalized Hunger: Fats are shown to be the most effective molecule to burn as fuel.
  • Epilepsy: Keto diet has been used since the early 1900’s to treat epilepsy successfully.
  • Cholesterol & Blood Pressure: shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup.
  • Insulin Resistance.
  • Improvements in your skin health.
Do Not Eat on a Keto Diet
  • Grains – wheat, corn, rice, cereal, etc.
  • Sugar – honey, agave, maple syrup, etc.
  • Fruit – apples, bananas, oranges, etc.
  • Tubers – potato, yams, etc.

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.

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.

Our sleep and wake patterns

On its own, the circadian rhythm takes almost 24 hours. Our bodies rely on the Sun to reset this cycle and keep it at 24 hours, the length of our days. Light and the dark are important signals for the cycle.

During the night, body temperature drops, metabolism slows, and the hormone melatonin rises dramatically. When the Sun comes up in the morning, melatonin has already started falling, and you wake up.

Our bodies in the dark

During the dark, levels of the hormone leptin (hunger control), go up. This means we do not feel hungry while low levels make us hungry.

Ans research found that sleep disruption and turning on lights lowers leptin levels which makes people hungry in the middle of the night.
