Let’s say you’re trying to lose weight and have unwittingly eaten 600 calories more than your body has burned for the day. You go jogging for 30 minutes at night, which burns about 300 calories, with maybe another hundred calories burned from the “afterburn” effect. You’re still 200 calories over your expenditure, and that means no reduction in total fat stores for the day—and maybe even an increase. You could continue like this for years and never get lean; instead, you could slowly get fatter. This is the most common reason why people simply “can’t lose weight no matter what they do.”
