You have to make the time to exercise, just like we make time to eat, sleep shower, etc. Exercise can make you less tired. Eat smaller meals more often with some protein at each meal, so you feel less likely to grab too many snacks. Protein keeps us fuller longer. Bring a cooler to work with you packed with your food for the day. Get up a half hour early in the morning, a few times a week, and do a 30 minute workout. Jillian Michaels 30 day shred is short and will kick your butt in to shape. If you belong to a gym, pack your clothes the night before and make yourself go a few times a week. Bring your sneakers and go for a walk on your lunch break. Don't make excuses. Find your motivation to live a long healthy life. Good luck!
