Cards

Term
stimulant, was banned in the US due to cardiovascular events and death
Definition
Ephedra
Term
prevents the enzyme alpha-amylase from binding with starches; starches cannot be broken down to sugars to be absorbed in the small intestine
Definition
Phaseolus Vulgaris (white bean) extract
Term
Binds to pancreatic lipases and inhibits their activity; decreases fat absorption by 25-30%; inhibits fat soluble vitamins
Definition
Orlistat (Alli, Xenical)
Term
Diets using this can backfire, may interfere with the ability to regulate food intake leading to inefficient use of calories and weight gain; body tastes fat and gears up to digest fat
Definition
Olestra (fake fat)
Term
Health study showed an average 3-4 lb weight loss when used over 3 months (consumed before each meal); resist weight gain and show no signs of metabolic syndrome
Definition
grapefruit
Term
activates the liver PPAR alpha receptor breaking down fat int oenergy; activates PPARy receptor increasing insulin sensitivity
Definition
Naringenin (antioxidant flavonoid derived from grapefruits)
Term
incretin hormone secreted by intestinal L-cells and some neurons which acts on beta-cells to stimulate insulin secretion and biosynthesis, decrease glucagon secretion, and promote pancreatic beta-cell growth
Definition
GLP-1
Term
produce over 80 proteins and hormones which control appetite, insulin resistance and INFLAMMATION
Definition
Fat cells
Term
Being 15-20% overweight prompts this in adipose tissue
Definition
phenotypic change
Term
Phenotypic change in adipose tissue due to obesity
Definition
results in protein, cytokine and epigenetic shifts favoring weight gain
Term
promote insulin resistance, fat gain and inflammation
Definition
Cytokines
Term
chronic, low grade inflammation
Definition
metaflammation
Term
Excess leptin from too many fat cells
Definition
Stimulates CD4 T cells to produce interferon gamma
Term
Interferon gamma
Definition
signals adipose cells to make histocompatibility complex II
Term
histocompatibility complex II
Definition
proteins expressed to combat virus and bacteria
Term
Excess fat
Definition
attracts immune cells like macrophages
Term
Macrophages
Definition
Form crown like structures aroudn fat cells who have outgrown their blood supply and died
Term
secrete pro-inflammatory cytokines promoting metabolic syndrome and metaflammation
Definition
Macrophages
Term
Obesity Metaflammation Response
Definition
Fat Gain; Less Energy; Hormonal Disruptions; Increases Disease Risk
Term
Fat Gain (Metaflammation Response)
Definition
Up-regulates fat storage enzymes; promotes inactivity and over-eating; disrupts carb metabolism; disrupts appetite regulation; causes brain inflammation
Term
The promoting of inactivity and over-eating by fat gain
Definition
down-regulation of neuropeptide Y and up-regulation of melanocortin pathways in hypothalamus
Term
Less Energy (Metaflammation Response)
Definition
Promotes small, dysfunctional mitochondria
Term
Hormonal Disruptions (Metaflammation Response)
Definition
Increases estrogen production which feminizes men; disrupts women's hormone cycle (PCOS) which increases testosterone in women
Term
Increases Disease Risk (metaflammation response)
Definition
increases risk of metabolic syndrome (insulin resistance, hypertension, elevated blood lipids, central obesity); increase cancer risk
Term
Work best for people who are less sensitive to insulin (25% of population)
Definition
low fat (20-30%), high carb diets (over 45%)
Term
more metabolically active; high amounts may elevate triglycerides and other blood lipids, increase inflammation, increased risk of metabolic syndrome disorder, lower levels of hormones and neurotransmitters, increase lean tissue loss
Definition
Carbohydrates
Term
many studies show that people lose more fat on this
Definition
higher fat (over 30%), lower carb diet (under 45%)
Term
decreased abdominal fat by 11%; better for insulin sensitive women
Definition
Higher fat diet
Term
shows lower triglycerides, LDL and increased HDL. Decreased abdominal fat, promotes fat loss while preserving lean tissue and muscle. Increase hormone levels, promotes immune system, reduces hunger
Definition
High protein diets
Term
as effective as calorie counting all week; does not lower metabolic rate and 'resets' body's carbohydrate metabolism
Definition
intermittent fasting
Term
Intermittent fasting metabolic changes
Definition
lower blood pressure, reduced cholesterol, lower fasting glucose, decreased metainflammation, reduced incidence of metabolic syndrome
Term
As effective as low calorie diets
Definition
intermittent low carb/high protein diets
Term
Several studies have found the best weight loss and health benefits are from:
Definition
low carb diet or fasting 2-3 days/week
Term
Low carb diet was superior to this in reducing weight, body fat and insulin resistance
Definition
low calorie and Mediterranean diet
Term
Epigenetic favorite reduces cardiovascular, metabolic syndrome and cancer risk
Definition
1/3 protein, 1/3 fat, 1/3 carb diet
Term
exercise, protein, spinach
Definition
metabolism boosters
Term
protein, dietary fiber, fat
Definition
appetite suppressors
Term
dietary fiber, exercise
Definition
absorption inhibitors: inhibit fat or sugar absorption
Term
omega 3 fats, moderate carb diet, exercise
Definition
metabolism modifiers
Term
exercise, higher protein diet, magnesium
Definition
stress relieving agents: decrease cortisol secretion
Term
increases muscle strength, fat loss, immunity, bone strength, also decreases blood pressure and blood lipids
Definition
whey protein shakes
Term
Over half of these are fake
Definition
Hoodia (appetite suppressor)
Term
Interact with medications
Definition
St. John's Wort (antidepressant), Cascara (laxative)
Term
can cause electrolyte imbalances (strong laxative)
Definition
Cascara
Term
can result in esophagus, bowel obstructions and even death
Definition
Glucomannan and guar gum (both fiber supplements)
Term
eating fake fat
Definition
may interfere with the ability to regulate food intake leading to inefficient use of calories and weight gain; body tastes fat (CD36 receptors) and gears up to digest fat
Term
when activated it breaks down fat into energy
Definition
PPAR alpha receptor in liver
Term
increases HDL cholesterol, decreases appetite, increase vitamin C intake and stimulates cytochrome p450
Definition
grapefruit
Term
improved insulin sensitivity and glycemic regulation in people with type 2 diabetes
Definition
whole grain barley
Term
normalizes carb metabolism; up-regulates energy metabolism; increases hormone production; increases muscle tissue; promotes a fat burning state in the body with increased energy levels; makes you feel and look younger
Definition
