  3. 3.  Substantial evidence, retrospective, prospective, animal & human,  Exercise has a neuroprotective effect (Kramer,Erickson,Colcombe)  Delay the onset of cognitive decline,Alzheimer’s  Proliferation of active capillary beds  New dendritic connections  Neuronal growth in hippocampus  Data demonstrated exercise several/week(Institute Brain Aging UCI) – Reduces rate of cognitive decline with age – Increases BDNF – Decreases B-amyloid
  4. 4.  Gunstad press Comprehensive Psychiatry – 408 subjects – 20-82 yo – Body mass index inversely related to performance all cognitive tests  Regular exercise improved cognitive performance  Overall sense of well-being
  5. 5.  Diet and exercise represent the mainstays of obesity treatment. No systematic review has been conducted comparing the effect of dietary and exercise intervention in reducing metabolic risks in overweight children.  To compare the effects of diet-only intervention with those of diet plus exercise or exercise only on weight loss and metabolic risk reduction in overweight children.

  8. 8.  Fifteen studies were identified 1975-2010  Both diet-only and diet plus exercise interventions resulted in weight loss and metabolic profile improvement.  Addition of exercise to dietary intervention led to greater improvements in – HDL – Fasting glucose, fasting insulin – triglycerides – Improved sense of well-being
  9. 9.  Dietary interventions in conjunction with exercise interventions are effective in reducing metabolic risks, particularly HDL-C and fasting insulin levels, in overweight and obese children
  10. 10.  How much is enough(exercise and weight loss)  Must be enjoyable – Reward – Negative reinforcement – Punishment  Aerobic vs anaerobic  Effect throughout life-cycle (peds-gero) – Gonadal steroid modulation  Fad diets vs sound nutritional intake – Many claims, limited data  Supplements, herbs etc  All things in moderation 02/05/15 RiverMend Health, LLC 10
