Do not blindly believe in articles (or in this case, the title)!
Without making changes in your dietary habits, consumption of this bullet coffee - coffee with added butter and/or coconut oil is likely to cause weight gain than weight loss, as it is high in calories and fat!
As explained by Dietitian Dr Sarah Schenker, ‘Ketosis is only triggered when the liver glycogen stores are depleted, so if you enjoyed a carb-heavy takeaway the night before, your morning cup of bullet coffee won’t be enough to make the switch.’
Enjoy your coffee black, or with milk, preferably low-fat or skimmed milk to minimise fat, sugar and calorie intake!
