... burn to create a deficit to lose 1 kg. Doing some research the general consensus seems to be approx 7700kcal. Suppose I eat a enough calories to exactly meet my TDEE and then consume a litre of Olive oil my caloric surplus would be approximately 8067kcal (according to nutritional information provided). This would mean that with this surplus slightly greater than 1kg of fat should be stored however due to the specific gravity of olive oil being approximately 0.91 that means that a litre of olive oil would only weigh 911 grams and couldn't possibly create more than 1kg of fat stored due to the law of conservation of mass. Any thoughts or explanations ? Thanks
