My first response to those people is usually this question: "how many calories are you eating each day?". I can almost guess what they are going to answer before they even tell me. Most people respond with a mind blowing 1,000 - 1,200.
People. LISTEN UP. Your body cannot function on only 1,000 - 1,200 calories a day when you are doing strenuous exercise! Your body will go into starvation mode and start holding on to EVERYTHING that goes in your mouth. Trust me - add in 300 or so extra calories and see where that gets you. I bet you will see a difference.
Now, there are many other reasons that your weight loss might have stalled or you might actually be *gasp* gaining weight. The article below was featured on the TeamBeachbody.com website and I loved it! Instead of recreating the wheel, I just copied and pasted it here for you to read. Much more efficient. Of course, you can always read the original HERE.
Read. Enjoy. LEARN!
