Study Notes

Energy Balance and Obesity

Energy balance refers to the equilibrium between the calories consumed through food and beverages and the calories expended through metabolic processes and physical activity.
The importance of energy balance:
- Weight management
- Metabolic health
- Physical performance
- Nutrient availability
- Cognitive function
- Hormonal regulation

Obesity Prevention and Management

Balanced diet
Active lifestyle
Family and friend support system
Policies and regulations

Herbs for Weight Loss

Cardamom:
- May support weight loss
- Animal study found that cardamom powder reduced belly fat in rats on a high-fat, high-carb diet
Fenugreek:
- May help control appetite and reduce food intake
- Studies found that fenugreek fiber increased feelings of fullness and reduced hunger and food intake
Ginger:
- May aid weight loss
- Review of 14 human studies showed that supplementing with ginger decreased body weight and belly fat
Ginseng:
- May aid weight loss
- Study found that taking Korean ginseng twice daily for eight weeks resulted in quantifiable reductions in body weight
Turmeric:
- May aid weight loss
- Study found that taking curcumin twice daily for one month was effective in enhancing fat loss and decreasing belly fat

Protein and Weight Loss

Protein changes the levels of several weight-regulating hormones:
- Increases levels of satiety hormones GLP-1, peptide YY, and cholecystokinin
- Reduces levels of the hunger hormone ghrelin
Digesting and metabolizing protein burns calories:
- Thermic effect of protein is higher (20-30%) compared to carbs (5-10%) and fat (0-3%)
Protein burns more calories (increases “calories out”):
- High protein intake tends to boost metabolism and increase calories burned
- Study found that overfeeding with a high protein diet increased calories burned by 260 per day
Protein reduces appetite (fewer calories):
- High protein intake leads to an automatic reduction in calorie intake
- Study found that protein at 30% of calories caused people to automatically drop their calorie intake by 441 calories per day
Protein cuts cravings and reduces desire for snacking:
- Study found that protein can have a powerful effect on both cravings and the desire to snack at night
Protein helps prevent muscle loss and metabolic slowdown:
- Eating plenty of protein can reduce muscle loss, which helps keep metabolic rate higher as you lose body fat
