Winter is definitely a tough time to start or continue a diet and exercise program. The holidays fill you up with a large quantity of unhealthy foods and beverages. It can also be a stressful or depressing time for many people so individuals are more susceptible to emotional eating or poor eating habits in general. The winter weather limits outdoor activities and the lack of sun and warmth can reduce motivation as well. The first step in my opinion to healthy weight loss, or more specifically fat loss (because muscle and water weight are beneficial and necessary), is to make a commitment to yourself and others that you will get healthier. Diet and exercise both go hand in hand, they are interdependent and you will only get limited benefits if you excel in one and not the other. Also, I believe that one healthy choice will often lead to another healthy choice so you just need to start that positive cycle and avoid the opposite cycle of unhealthy behaviors. You also just have to go out and do it. I've found that you might dread it, and it might suck in the beginning, but 5 or 10 minutes into it and by the end of it you'll be happy you got that workout in. And you will definitely thank yourself down the road.
