If you've been trying to lose weight but are finding it challenging after a certain point, it might be time to consider cutting the carbs.

That's according to Dr. Jim LaValle, author of 'Cracking the Metabolic Code' and Clinical Director for the Performance Health Program for the Pro Football Hall of Fame. He says a lot of times not only can carbs hold you back in your weight loss journey, but they can also make you feel bad.

Dr. LaValle says to know for sure if certain foods are contributing to your weight loss challenges is called the elimination diet. He says you remove 'the big three' and see what your progress is after a few weeks and then you can slowly add a few things back to your diet and monitor how you respond both physically and psychologically.

Another component is dealing with gluten. Dr. LaValle indicates it is important to monitor how you feel after you eat certain foods.

If you try these things and they do not work, Dr. LaValle says it is important to consult your doctor and maybe get some blood work done.
