  2. Lose Fat…Not Muscle! • 1-2 pounds per week is recommended • Faster weight loss usually mans loss of water and muscle • 1lb/week = 500 calories/day (eat less or exercise more) • Remember 1 lb = 3500 kcal

  3. Energy Balance is Easy! • 40% of adults are trying to lose weight on any given day.

  4. 3 options for weight loss • Diet only • Reduce calories coming in • Exercise only • Increase calories going out • Combine Diet and Exercise • Best option! • Reduce calories coming in and increase calories going out.

  5. Diet only • Reduction in metabolism • Loss of water • Loss of fat free mass • Loss of fat mass

  6. Exercise only • Slow and gradual • Most people want a “quick fix”

  7. Diet AND Exercise • Reduce calories coming in (300-500 kcal) • Increase calories burned (300-500) • Offset decrease in metabolism • Keep most of your muscle • ACSM recommended weight loss in 1 week = 2 lbs or less

  8. Healthy Weight-Loss Strategies • Eat 1,700 to 1,800 calories to meet your body’s energy needs • Remember your BMR • Include your favorites in moderation • 80/20 rule • Eat a variety of low-calorie, nutrient dense foods • Drink plenty of water

  9. Being Underweight Can Also Be Risky • Underweight – a condition in which a person is less than the standard weight range for his or her height • May be normal • Genetics • Fast metabolism • Some diet to stay extremely thin • Little stored fat (energy reserve) • May not get enough calories and nutrients for healthy growth • Can lead to fatigue and decreased ability to fight disease

  10. Healthy Weight-Gain Strategies • Increase your calorie intake • Eat often and take second helpings • Eat nutritious snacks • Build muscle • Resistance training

  11. Going ON a diet suggests that you will go OFF… Aim for LIFESTYLE CHANGES!!!

  12. The diet industry • The dieting industry is a $40 billion industry • Americans spend yearly… • $2.4 billion on pre-packaged weight loss meals • $1.7 billion on weight loss shakes • $15 billion on diet soda

  13. Dieting today • Today • 70% of high school girls have tried to diet at least once • 1964 • Only 15% of American adults were dieting

  14. Fad Diets • Weight-loss plans that are popular for only a short time • May promise quick and easy weight loss • Most very low calorie • Weight loss is not permanent • Associated with medical problems • Impaired glucose tolerance, liver and G-I abnormalities, sudden death

  15. Low Carb Diets • Ex ) Atkins • Idea is that if you restrict carbs…your body will burn fat • Problem – your body needs carbs to burn fat • Not healthy in the long-term because they are low in grains, fruits, and veggies

  16. Liquid formulas • Ex) Slimfast • Lowers the number of calories per day by replacing meals with liquid • This can be dangerous – most likely not getting all of the nutrients your body needs!

  17. Stimulants • Ex) ephedra, caffeine • Reduce appetite and give a feeling of energy • Bad side effects – nervousness, dizziness, headache, increased blood pressure, heart attacks, and seizures

  18. Fasting • Not eating • Weight loss is initially rapid as the body uses fat stores for energy • Body proteins are broken down to provide the missing energy = loss of muscle mass

  19. Diet Pills • A pill that causes you to lose weight without the need for low calorie diets and exercise • No SAFE pill exists! • Only 1 diet pill is approved by the FDA • Diet pills can claim whatever they want – don’t have to have scientific proof

  20. Surgery • Gastric bypass – changes the structure of the digestive tract by bypassing part of the stomach • Reduces the amount of food you can eat

  21. Weight Cycling • The repeated pattern of loss and regain of body weight • People on diets gain more weight than non-dieters • Dieters lost 1 billion lbs/year and GAINED 1.2 billion pounds • Within 5 years 95% of dieters will regain all the weight they lost
