Hi Freedom! 
ANY time of day is best for exercise. Unfortunately there is this mindset that we must exercise at such-and-such a time only but that is untrue. Whether you walk a mile in the morning or at night you are still burning the same calories. Burning calories is what causes us to lose weight. When we burn more calories than we consume. I know it’s simplistic but sometimes we lose focus of the basics and we need to be reeled back in. 
A time of day, hormones or magic pills don’t make you burn more or less calories. It’s how much physical effort you put into exercising.
The point is to do it when you are least emotionally and physically tired so that you will be able to enjoy the invigoration that exercise often brings. Figure out when this is for you. Definitely not directly after a meal; give yourself time to digest first.
When we set rigid rules about when we can exercise we find that suddenly things get in the way of our schedules and we miss our window of opportunity. Spontaneity is the key.
It’s the same with eating. It is easier to eat spontaneously and listen for your body’s hunger cues rather than force yourself into eating 3 big meals a day. This is where people get the idea that you eat several small meals a day.
This is why the dieting and exercise industry makes so much money, because it fails. If anything worked exactly then it’d be that one thing only that we’d see selling like hotcakes.
Definitely make yourself a "To-Do" list for the day and have exercise be on that list. It’s up to you how many times during the day you want to exercise and for how long. It may be easier for you to find a few 15 minute windows here and there throughout the day to get some exercise in, or, it may be easier to do it all at once.
What I find that helps is trying to do a little here and there. I try to get strength training in first (it truly invigorates me). Maintaining and working lean muscles really eats up the fat. Burning calories is essentially but lean muscle mass is a must as well. Later on in the day I walk fast, run, or jog. This really restokes my inner fire and pumps me up. I usually do this in the later afternoon when I’m sick of doing chores, bored or want to procrastinate from something else. After doing that I have a renewed sense of accomplishment and am able to get back to whatever I was doing.
The key is to set a goal for what you’d like to do each day and tell yourself "No excuses, one way or another its getting done." Then you just have to find what works for you. Since each body is different and no two people maintain homeostasis the same then only you will discover what your body needs for weight reduction. You CAN do it.
All things in moderation!
Also, learning new ways too cook and eat can help. Cooking Light tends to have great recipes and I really like cookbooks that do a fat and calorie makeover of comfort foods (such as "More Healthy Homestyle Cooking: Family Favorites You’ll Make Again And Again" by Evelyn Tribole). By adapting this kind of cooking into your repertoire you learn how to easily make substitutions later on.
Another thing that helps with weight loss is to not look at food as good or bad, but just for what it is: Fuel for the body. When you start to see food in this light your eating habits change and you find you are practically able to eat what you want but your mentality about food changes. In other words, sure, a chocolate cookie would taste so good right now but how much nutritional benefit will my body get from it, considering I’m going to workout soon? I’ll stick with the granola, cherries and vanilla yogurt- it tastes just as good and has more vital nutrients that my body needs. I’ll save the cookie for later. Thinking like that.
Sorry, I carried on longer than I meant to. I am really passionate about being healthy but in a gentle, simplistic light. You can do it! Godspeed!
