Medical Weight Loss Updates CarbohydatesFor many years, Dr. Lazarus and the staff at CNC have utilized low carbohydrate diets to achieve weight loss. This remains a common practice among medical weight loss doctors. But what about long-term maintenance of weight loss?

Even after a successful weight loss with a low carbohydrate diet, many individuals struggle with weight regain. A common explanation is that we go back to our old habits, thus returning to our former weight. Part 1 of this series casts doubt on this explanation (read more about the energy gap here). But, really if a low carbohydrate diet was used for weight loss, the low-carbohydrate diet should be continued. Why are low carbohydrate diets helpful for long-term weight loss? Here are several explanations:

  • Assuming adequate protein on the low carbohydrate diet, there is less loss of lean body weight preserving metabolism. This study was published earlier this year (Ebbeling CB, JAMA 2012).
  • It takes a lot of energy to process protein. In fact, more energy is used to process protein compared to carbohydrates or fat.
  • With low carbohydrates available, our body’s must make glucose from protein, which also utilizes a lot of energy.
  • The foods we eat suppress appetite differently in this order:
    Protein > Fat > Carbohydrates
    (Batterham RL, Cell Metabolism 2006)
    So, high protein diets are much more satiating than high fat diets or high carbohydrate diets. In fact, the more fat is present in a meal, the more fat we will eat, without even being aware of the calories we consumed.
