Tips for maintaining weight loss

Tips for maintaining weight loss

We expend energy (burn calories) through three main pathways:

  • Resting Metabolic Rate (RMR) – 60-75% of energy expenditure. The energy used by all of the vital processes and organs throughout the body.
  • Activity Energy Expenditure (AEE) – 17-32% of energy expenditure depending on your activity levels, and includes exercise and NEAT. NEAT stands for non-exercise activity thermogenesis, and is the energy used for everything that is not resting, eating or exercise. It ranges from walking, typing and house jobs to fidgeting.
  • Thermic Effect of Feeding (TEF) – approximately 8%. The energy used to process, digest, absorb and distribute foods/nutrients.

It is extremely common for those who lose weight to regain the weight lost quickly, and this is not surprising due to several physiological adaptations that occur. Lets take a look at what changes physiologically and why this may lead to the weight re-gain:

  • A decrease in resting metabolic rate (RMR), which results in less energy being used to sustain bodily functions.
  • An unconscious reduction in exercise and activity (AEE) decreasing total energy expenditure.
  • An increase in efficiency during exercise. Therefore, the energy used during exercise is significantly less as the body becomes more efficient.
  • An increase in appetite due to changes in hormone levels such as ghrelin and leptin that increase your desire to eat.

Recommendations for Maintaining Weight Loss

  • The diet used to facilitate weight loss has to be sustained, if you return to your previous eating habits you will regain the weight lost.
  • Therefore, choose a diet that is realistic and you can adhere to.
  • There must be a conscious effort to increase activity and exercise (AEE) to compensate for the unconscious decrease in exercise and increase in efficiency (less energy used during exercise).
  • Increasing protein intake has a large satiating effect (makes you feel fuller for longer), and can result in a reduced food/calorie intake.
  • Spacing your meals out throughout the day and increasing protein intake can offset feelings of hunger.
  • Ensure your diet contains a wide variety of foods to avoid deficiencies.
