Summary of Transcript:
In this video, Thomas DeLauer discusses how our metabolism slows down when we lose weight. He references a study that showed after just 13 days of consuming 1100 calories per day, there was a 17-20% reduction in the resting energy expenditure. He then discusses two longer-term studies which showed that after 8 weeks of 500 calorie severe deficit, there was not only a decrease in metabolism associated with weight loss, but an enhanced decrease in metabolism above and beyond that associated with weight. He then references a mice study which showed that when obese mice lost weight, their bacteria was placed in lean mice which caused the lean mice to immediately start gaining weight. He concludes by discussing how intermittent fasting can be a good way to maintain a healthy metabolism as it triggers metabolic responses in the body and has a mild increase in metabolism during the fast.

Understanding Why Weight Loss Slows When Dieting
When it comes to weight loss, it is important to understand why it slows down when dieting in order to safely lose weight and maintain weight loss. Low-calorie diets can lead to a decrease in metabolic rate, which can make weight loss more difficult. Fasting can also be used for weight loss, but it is important to understand the effects it can have on weight maintenance. Finally, a study of The Biggest Loser contestants showed that the contestants’ metabolic rates decreased significantly after the show.
Low-Calorie Diets & Metabolic Rate
Research has shown that low-calorie diets can lead to a decrease in metabolic rate, which can make weight loss more difficult. A study published in the Journal of Applied Physiology found that a low-calorie diet could lead to a 10-15% decrease in metabolic rate. Another study published in the American Journal of Clinical Nutrition found that a low-calorie diet could lead to a decrease in resting metabolic rate of up to 20%.
Fasting for Weight Loss & Weight Maintenance
Fasting has become increasingly popular for weight loss. While it can be effective for weight loss, it is important to understand the effects it can have on weight maintenance. A study published in Nature found that fasting can lead to a decrease in metabolic rate, which can make it more difficult to maintain weight loss. Another study published in Diabetes Care found that fasting can lead to a decrease in resting metabolic rate of up to 10%.
The Biggest Loser Contestants
A study of The Biggest Loser contestants showed that the contestants’ metabolic rates decreased significantly after the show. The study, which was published in the journal Obesity, found that the contestants’ metabolic rates decreased by an average of 500 calories per day after the show.
How Fast Does Your Metabolism Slow Down when Dieting?
The exact rate at which your metabolism slows down when dieting can vary depending on the type of diet you are following and your individual physiology. However, research has shown that low-calorie diets can lead to a decrease in metabolic rate of up to 20%, and fasting can lead to a decrease in resting metabolic rate of up to 10%.
