I highly recommend the book The Obesity Code to give you some additional insights into how to lose the rest and also keep it off.
Some of the insights he has:
Your body has a set weight that it will work really hard to get you back to. Most of the contestants on The Biggest Loser end up regaining all of their weight because of this.
The key to resetting your body’s set weight is lower your insulin resistance via long term fasting and avoiding snacking.
Long term fasting (longer than 2 days) has a massive amount of health, mental and longevity benefits.
Plant based diets are hugely important.
