How often does the stomach lining replace itself?
The reason why the stomach lining keeps replacing itself, every 3 to 4 days, is that it would, otherwise, dissolve due to our strong digestive acids. An ulcer is when the stomach acids burn through the lining quicker than it can replace itself. Ouch!!
Does physical activity trump genetic expression?
The Institute of Metabolic Science in the UK report that even small amounts of exercise (30 minutes a day for 5 days a week) can counter the DNA predisposition to obesity. This physical activity can include walking the dog, gardening, or commuting to work by bike.
This study focused on the FTO gene which was first linked to obesity in 2007; people with this gene were measured to have a 30% higher risk of obesity. This gene is common: 74% Europeans, 76% African Americans, and 44% of Asian descent carry this gene.
They found that if people exercised the risk of obesity could drop by 27%.
In order to confirm this statistic, the researchers went back to all FTO gene studies (both published and unpublished) in order to standarize the data. They found that more than one hour of moderate to vigorous activity a week, was enough to influence this particular gene.
The researchers were not able to determine how exercise trumped the effects of genes, just that it did.

What's the difference between being trapped and being stuck?
A most respectable psychologist, Ben Michaelis, recently pondered on the difference between being trapped and being stuck. He wrote that being trapped, is when struggling to get free, sinks you deeper into trouble...like ignoring debt generates even more debt via fines, interest, and penalties.
Being stuck, though, even though it may feel as if trapped, still allows one to get free with enough patience and effort.
Dr Michaelis's three tips to avoid falling the trap of feeling trapped is to:
1) Reframe the situation. Say, "I am not trapped, just stuck". say it over and over again.
2) Take one action. Do one small thing to begin getting unstuck. One small step is a reminder that change is within reach.
3) Commit to doing one thing the next day. Write it on a piece of paper and put it somewhere prominent so you will sure to see it.
Repeat numbers 2 and 3 each day until momentum is yours and the feeling of being trapped has faded.

3) Pay attention to hunger.
