1. Not Eating Enough
With today's societal pressures, you may feel like this the exact opposite of your current concerns. Often, we try to limit our calories, and while that does technically play a role in weight loss — we can't forget that calorie intake is actually essential to our body functioning properly and healthily. 

If you're trying to lose weight, drastically cutting calories doesn't help in the long-term. Your body enters 'survival mode,' and instead tries to hold onto as many calories as it can. Not eating enough affects your physical and mental health, so be sure you're taking in adequate food and approach eating from a nutritional perspective.
