Episode notes
Diet vs. Exercise Impact
- Calories consumed from diet have about 20 times more impact on weight than calories burned by exercise.
- Basal metabolic rate accounts for about 60% of daily calorie burn, greatly outweighing calories burned through physical activity.
Exercise Alone Limited Weight Loss
- Exercise alone typically leads to minimal weight loss, around one pound every six weeks on average.
- Adding exercise to diet results in only about two additional pounds lost over months, often not clinically significant.
Beware Exercise Calorie Overestimation
- Do not overestimate exercise’s ability to burn calories.
- Remember an hour of brisk walking is needed to burn off just one slice of pizza.
