Most people are familiar with calories but few know exactly what they are. Calories are units of measure assigned to foods to show how much energy it contains. Your body expends a certain number of calories as energy everyday. If you consume more calories than you expend, the excess will be stored as body fat. If you consume less than you expend everyday your body will have to use stored body fat to meet energy needs.
If you're among the 30% of Americans who sleep less than six hours a night, here's one simple way to whittle your waistline: catch more Zs. A 16-year study of almost 70,000 women found that those who slept five hours or less a night were 30% more likely to gain 30 or more pounds than those who slept 7 hours. The National Institutes of Health suggest adults sleep seven to eight hours a night.
I felt like I had a pretty good grasp on nutrition, but what mid 20-30s female doesn't suffer from constant pressure to be as skinny and fit as possible!? My first marriage was falling apart when I decided to pick up racing, and the training was a good escape. I had managed to get a little more fit with P90X but I really enjoyed my YMCA family more than Tony and sweating it out in a garage. Plus, I grew up in the south and truly enjoy experiencing food wherever we are (my mom should have been a pro, but my little brother is a chef! We really love to eat) I managed my fitness with Y memberships and what I thought was "balanced eating" but even in triathlons I needed a racing coach and a separate nutritionist. I know I was guilty of the "I rode 40 miles and ran 10" I can eat what I want mindset and luckily my mid 30's seemed to allow for that! Even though I experienced success and thought that the racing got me into the best shape I had been, I still felt all over the place with fitness and nutrition. Add in migraines, less an less "quality" sleep, fatigue and a metabolic panel suddenly all over the place, I was ready for something that was consistent, manageable, and did a lifestyle improvement rather than a quick fix.
On high carb days protein intake should be lowered to 0.95 gram per pound of body weight. To calculate this you must multiply your body weight by 0.95. This means if you weigh 180 lbs. then on your high carb days you should eat 180 grams of protein. Don’t worry about losing any muscle mass as a result of lowering protein. The higher insulin levels from the extra carbs will be more than enough to preserve muscle.
When food intake and carbs are low, leptin levels will lower. This will send signals to the body that energy intake is low and the metabolism must be lowered to compensate for the lack of incoming energy. When carbs are kept in the diet it will help keep elevated levels of leptin and other fat burning hormones even when total calorie intake is low.
