Knowing the main causes behind weight gain is very important towards successful weight loss.
A lot of us know that it is not wise to consume fast foods and fried foods; however, what are some of the lesser known evils of obesity.
In this article I will list three factors which influence weight gain.

1. Lack of physical activity.
   Routine physical activity is very important for those individuals who want to stay thin and fit.
   Exercise increases your metabolism; helps you burn more calories and build muscle.
   
2. Poor nutrition habits.
   There are many things we can do in order to improve our nutrition habits.
   We can switch form refined grains to whole grains.
   We can switch from whole milk to low fat dairy.
   We can consume fish at least twice a week.
   We can replace some of our meat with beans.
   Healthy meal preparation can also help us achieve a slimmer physique.
   Instead of frying, we can try grilling and steaming.
   It is also beneficial to consume plenty of fresh fruits and vegetables.
   Fresh produce provide our bodies with vitamins, minerals and fiber.
   
3. Poor Meal Planning.
   Consuming food too often or too far apart can have bad results.
   When we starve ourselves majority of the day in order to consume fewer calories, we are only setting ourselves up for mindless snacking and overeating.
   The best thing is to consume mini meals every 3 to 4 hours.
   These mini meals should consist of some sort of protein and fiber (to help you feel full longer).
   

These are three of the main causes behind weight gain.
Being smart about your eating habits and fitness regimens can help you lose weight.
Other valuable tools include all natural diet pills (such as hoodia) and whey nutrimelt protein shakes.
