Best weight vs Ideal weight

For half a century, doctors and researchers have known two things that could have improved, or saved, millions of lives:

• Diets do not work. Not just paleo or Atkins or Weight Watchers or Goop, but all diets.
• Being fat does not necessarily mean being unhealthy.

• A 2016 study that followed participants for an average of 19 years found that unfit skinny people were twice as likely to get diabetes as fat people, who were relatively fit.
• Americans spend more on dieting every year than on video games or movies.

The body is an orchestra of organs, each providing an essential function. In this metaphor, the circadian rhythm is the conductor. The conductor makes every neurotransmitter, every hormone, and every chemical in the body cycle with the daily rhythm.

This makes us our sleep habits unique and tailored.

Being a morning (or evening) person is inborn, genetic, and very hard to change.

• 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 .

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. 

Eggs have a lot of cholesterol compared to other foods. Although cholesterol in the blood is strongly related to heart disease, eating cholesterol is weakly associated with raising the cholesterol levels in your blood.

Eggs have other heart-protecting properties and eating it probably won't harm your heart.

• A chain email in the 1990s was responsible for the false belief that antiperspirant was raising the risk of breast cancer. 
• When researchers found higher ratios of aluminum in the brains of Alzheimer's patients, aluminum in antiperspirant was suspect. But it seems aluminum in antiperspirant is hardly absorbed by your skin.
  
  

Keto is more than just a diet. It is a cultural identity.

The Keto diet changes how adherents think about medicine and nutrition. With the fake news that dominates the news cycle, it's not surprising that keto went viral. It's anti-establishment.

The body can only store glucose to last a few days. If we don't eat carbs, the body finds other ways to fuel the body, like ketogenesis. In ketogenesis:

• The liver starts to break down fat from food and our body reserves. The useful energy source is called ketone bodies and can replace glucose as fuel when there's a glucose shortage.
• Once ketogenesis starts, the ketone levels rise.
• The body burns fat instead of the usual glucose.

• BMI doesn't distinguish between body fat and muscle mass. Muscle weighs about 18 percent more than the same amount of fat. So, according to BMI, the muscled person is more overweight than a sedentary person.
• BMI is also not reliable to use on elderly adults, who continue to lose muscle and bone mass with age. An overweight older adult may appear to be within a normal BMI range.
• The BMI calculation is based on Caucasian body types and may not be appropriate for people of other ethnicities.

A person whose BMI indicates they are overweight or obese is generally considered unhealthy. But 2016 research suggested that this was incorrect for 75 million Americans.

• Researchers found that 54 million Americans that were classed as overweight or obese were perfectly healthy when they considered the cardiometabolic measures (blood pressure, blood sugar, cholesterol, etc.)
• 21 Million people were classed normal in terms of BMI, but other cardiometabolic tests indicated they were unhealthy.

Exercise is like a wonder drug for many health outcomes: reducing blood pressure, reduces the risk of diabetes of heart diseases and slows developing cognitive impairment from Alzheimer's and dementia. 

But as for losing weight, it helps more in weight maintenance than in losing the actual weight.

Exercise alone has a modest contribution to weight loss. But when you alter one component, cutting the number of calories you eat in a day to lose weight, doing more exercise than usual, this sets off a cascade of changes in the body that affect how many calories you use up and, in turn, your bodyweight.

Losing weight through changing what and how much you eat doesn't happen because you rationally decide to lose weight. You have to have a change of heart.

To get in touch with your motivation, think about the negative consequences of not changing as well as the positive ones. Successful individuals keep their motivation in the forefront of their minds all the time.
