Have you ever wondered why it is so hard to keep the weight off once you have reached your goal weight?
Well, a new study (published in the journal Obesity) has revealed that it is because as you lose weight your appetite increases.
According to the research your body will crave an extra 100 calories for every 2 pounds it loses.
What research was undertaken?
During this study 242 people with type 2 diabetes were given a daily dose of Invokana, a new diabetes drug or a placebo pill.
This new drug is designed to help reduce blood sugar levels by causing you to dump some through your urine.
As this sugar is lost so will the amount of calories you absorb.
Scott Kahan, MD, director of the National Center for Weight and Wellness at George Washington University in Washington, DC had this to say about the drug:
“Getting rid of those calories also leads to weight loss, but in a covert way.”
“People don’t notice major changes in weight from the medication, but it’s enough that we can study what the change in weight and appetite would be.”
At the end of the year long study both groups lost weight, although those who took the Invokana drug lost the most.
The 89 people in the placebo group lost around 2 pounds, while those in the Invokana group lost an average of 7 pounds.
From looking at an equation they created the researchers were able to conclude that while the drug was causing weight loss, the bodies of the volunteers were fighting against the losses, prompting them to eat more to make up the calorie deficit.
The researchers concluded that if someone who would usually eat 2,700 calories daily lost 9 pounds, their bodies would prompt them to eat around 400 calories more than before to regain the lost weight. This would mean that they were eating 3,100 calories daily.
What else causes you to regain this lost weight?
This is not the first study to show why it is hard to keep the weight off.
Another study from earlier in the year showed that your bodies ability to burn calories at rest (your resting metabolism or RMR) slows down as you lose weight, making it easy to regain weight.
