After the summer of hell on the treadmill, I started running outside and built my endurance. I bought myself a pair of good running shoes and used the MapMyRun app to track where I was going and how far I went. Some days of running were great and I could go for three miles and feel awesome the entire run, but then other days were so bad. I remember there were times I was in the middle of a run and wanted so bad to give up and I would have to walk for a little bit to give myself a break before running again. I remember sometimes I would get so discouraged that I would cry and call Alan to see if he could pick me up because I gave up on myself in the middle of a run. Again, I had to learn to give myself grace on the days when I didn’t do as well as I wanted because I knew that in terms of big-picture, I was slowly making progress. I trained my body to relate exercise as a way of relaxation.
People who get enough sleep tend to weigh less than those who don't. Additionally, researchers found that well-rested dieters lost more fat than those who were sleep deprived, who lost more muscle. "Whenever I don't sleep enough, I'm ravenous the next day," says Weil. To keep her hunger in check and help her maintain her slim figure, she tries to get at least 8 hours of sleep every night.
That first summer of all in was the summer of forming healthy habits and making lifestyle changes. They say (who is they? the internet? scientists?) it takes 30 days of doing something every day to form a habit. While that might be true for most people, it wasn’t for me because it took me the entire summer to form my habits. My nutrition habits were focused on eating nutritious foods and figuring out what those were. Specifically, I wanted to eat nutritious foods that fueled my body, figure out the right amount of foods I needed, eat less processed foods, and monitor sweets. My exercise habits were focused on incorporating activity into each day. Specifically, I wanted to start running, lifting, and be active every day.
The key to losing weight is eating fewer calories than you expend. That creates an energy deficit, so your body taps into other sources of fuel — namely, your fat stores — to make up the difference. You’ll be able to lose weight safely by creating an energy deficit of up to 1,000 calories a day, which will allow you to lose up to two pounds per week.
Research shows your body also unleashes human growth hormone, which helps you burn fat and maintain muscle, after just 10 to 30 seconds of high-intensity exercise. High-intensity exercise also appears to help curb your appetite and trigger hormones that regulate feelings of hunger and fullness better than lower-intensity exercise, so you’re less likely to overeat.
