2017 Goals
Health
I'm going to take care of myself. The biggest change I'm going to make is in regards to my eating habits. I've decided to try "clean eating." I eat relatively well when I'm in school working, but otherwise I'm terrible at making eating choices. I am going to cook meals at least 5 nights every week, and take my lunch to school everyday. Secondly, I'm going to attempt to eliminate sugar. This will be hard, but I feel I'll be able to do it. I'm aware that I will probably fail, but I'm determined to get back on track if I do. Lastly, I'm going to try to eat breakfast. I enjoy sleeping for as long as possible, so I'm sure this will be difficult.
Activity
2016 was a terrible year for activity for me. I was active sporadically, but nowhere near where I usually have been. I've decided to re-claim my running and swimming habits. My goal is to run 500 miles over the course of the year. I figure if I run a couple of miles every day or 3-4 every other day, I should be able to reach that goal. I know some of the runs I do will be more than the daily goals. I am going to record my workouts on my calendar to track how many miles I run per week.
My second activity goal is to attend yoga again. I'm learning that as I get older, stretching and strengthening are more important than simple cardio. Once I'm done with basketball season, I am going to attend hot yoga classes again. Perhaps I can convince someone else to attend with me.
Reading
Usually during the school year, I end up reading only textbooks and articles related to the subject matter that I'm teaching. I want to read one non-school book per month. In addition, I will attempt to not purchase any new books during this year. I am committing to using my library. I figure that since I pay my taxes I should take advantage of them!
Writing
I've been scribbling down scenes and chapters for a very long time now, but I want to really commit to it this year. I watch those Hallmark movies all the time and think, "I could totally write that!" I want to try to pen a screenplay or novel. Writing will be hard because it's something that needs to be done while alone, but I will try to find time every weekend to write for at least an hour. Even if the finished product is no good, at least I will have something to show for my effort.
Here's to 2017!

Epigenetics and obesity
Leptin; made in white adipose tissue. (Brown fat: needed for thermoregulation...mostly limited in humans...babies and eskimos) amount is directly proportional to amount of fat in the body; signals to the hypothalamus that body is full and to stop eating. LETPIN=DECREASE FOOD INTAKE
Insulin; tells liver, muscle, and fat to take in glucose from blood; released from pancreas when glucose is high; can enter the brain and signal hypothalamus to reduce food intake. Type 2 diabetes=lifestyle choices; insensitive to insulin
Ghrelin; produced by stomach and pancreas; induces feeding and storage of fat; signals hypothalamus to increase food intake.
Hypothalamus: responsible for a lot of homeostasis. 2 types of neurons: Neuron 1= neuropeptide Y and agouti related protein which when activated lead to increased feeding; Neuron 2=proopiomelanocortin (POMC) which leads to decreased food intake; can help with weight loss.
Dopamine (neurotransmitter); reward drug...keeps
How can we change obesity?
Clocc: Childhood Obesity:
Why should we help obesity decline?
Many diseases of obesity
Systems are affected by obesity
Society is paying for it! You can save money if there were no complications.
How can we help?
Education-nutrition
after school activities
student ambassadors
mass media
access to healthy food
encourage parent support & peer leadership
Change policies in the schools and neighborhoods
Contributing to the problem:
More processed food in more developed countries
Less family time
Activity:
Do some research and find data for obesity. Obesity rates; diabetes rates; maybe start locally and see if any research was done
Environmental and genetic factors contribute to obesity.
Environment has no effect on intergenerational traits
Epigenetics: Conrad waddington
One genotype gives multiple phenotypes depending on environment during development.
Certain nutrients need to be given during development.
Changes in dna methylation can contribute to obesity,stroke, atherosclerosis.
Nutrition and epigenetics:
Viewed methyl donors (like folate).
Veg diet influence methylation patterns
Changes in methylation due to changes in early life nutrition.
Nutrition is extremely important for genetics and the exposure to obesity. The predisposition to obesity.
Rations for Dutch during ww2. Famine in netherlands. So there are details of caloric intake. Compares siblings who were born before famine and those born after. Later kids (lower birth weights) have predisposition to obesity, cardiovascular disease, and psychiatric disorders.
Low birth weight women more likely to have low birth weight children. So they are predisposed to getting obesity in later life.
Epigenetics modifications can be reversed. Early intervention is imperative.
Longer time breastfeeding can lead to Lower possibility for obesity.
