SNIFFING OUT DANGER
For extreme low-carbers. When ketones the by-product of a body burning gat instead of carbs, become too elevated in the blood, they can release an alcohol-like odor.
High-protein diets can produce a bleach or ammonia scent, a sing that muscle might be being used instead of fat for fuel, which can slow metabolism, making it harder to keep off weight.
Picky eaters or those trying to restrict their calorie intake may over-spice the select or bland things they regularly consume, which can cause a garlicky aroma.
If you're catching weird whiffs, see your GP and, ideally, an R.D., who will help get your body running efficiently again.
