Bahar Takhtehchian, a lifestyle expert and the founder of Bahartak.com</a>, shares her tips for surviving the holiday season with your waistline intact.<br /><br />Eat Healthy Fats<br /><br />[caption id="attachment_1001687702" align="alignnone" width="384"] Getty[/caption]<br /><br />Not all fats are bad for you! In particular, unsaturated fats — found in avocados, almonds, and walnuts — increase satiety, improve insulin metabolism and help your body to absorb vitamins.<br /><br />Try a New Workout<br /><br /><br />Crummy weather isn’t an excuse to lounge around the house. When the temperature drops, stay active by trying a new activity, such as indoor cycling or running on the treadmill, both of which will help get your pulse rate up quickly.<br /><br />Add a Supplement<br /><br /><br />A dietary supplement can help you achieve weight-loss goals. Zantrex has a range of formulas that the brand says let you not only lose weight, but keep those winter pounds off as well. (Available at Walmart, Amazon and zantrex.com.)
