i think it's a pretty good plan. because when you start planning on exercising out your diet, well, you end up having that 800 cal starbucks muffin. because, you know, you're going to work out this afternoon. then you might supersize your lunch. you know, because you're going to work out this afternoon. and when you have dinner, well, you pick up dessert and maybe a little larger portion because you're working out later. and while you do need to increase your intake if you are working out a lot, most people who try to use the "i work out so of course i should have this" thought process seem to think they are michael phelps' training partner, and that's what gets them when they try and use exercise that way. i mean, if you really are working out in a manner that's comparable to michael phelps' training regimen, you can do that and more. but i would guesstimate that most people burn less than 7000 cals a week through exercise. which translates to less than 1000 cals burned a day through exercise. so having one of those is doable. two maybe. but when people get themselves into that mentality, they tend to overspend their workout calories [in other words, if their workout was 400 cals they'll spend 200 on a chocolate milk after, 200 on two glasses of wine with dinner, have a yogurt and granola for 200, have an extra square or two of chocolate as a treat, and if you've noticed they have already eaten back what they burned and then some.]. and then if they start skipping workouts, they don't cut back.
that's why diet is far more important. you do factor in exercise, but it can do a lot more than exercise, seeing as how most people have bmrs of well over 1000. and that and daily activities account for at least 2/3 of most people's total daily burn. so even a person working out 1000 cals a day isn't going to be able to burn more through exercise than living and whatever else they do in a day. and in that sense it's easier to focus on the thing that has the most impact.

Well, how easy is it to "not eat" a 300 calorie cheeseburger. And how long does it take to burn 300 calories in the gym?

It's a heck of a lot easier to make healthy dietary choices to reduce a few calories per day than to exercise them away. Hence the 80/20 thing - even small changes in your diet can mean massive amounts of calories restricted daily but it can take loads of exercise to burn off the same numbers.

Basically, what it means isn't that there's some kind of mathematical accuracy to it, but rather it's an easy way to remember what matters.

You can do all the exercise in the world you like, but if you don't get your diet under control... you won't lose. If you've ever been to a gym, you've seen them. The women who sit on the thigh-working machines, talking and barely trying, but never change their diet. They vanish after a few weeks, because nothing happens.

Getting fit and losing weight is a lifestyle change, and frankly... you can't lose weight if you keep doing the same things you were before. Most of your effort should be in the kitchen, followed by a balanced, complete exercise plan to supplement it!

A couple of thoughts: exercise helps with your physical strength, flexibility, & heart health--but you cannot chase a poor diet w/ exercise an expect a positive outcome.

The food(s) you choose to feed your body will affect the extended chemistry of the body. Think NUTRITARIAN. Typically many tend to eat high calorie, low nutrition. But gains are made in feeding your body excellent nutrition--especially fruits & veggies. (check out "Eat to Live" by Dr. Joel Fuhrman)

It's like "Genius is one percent inspiration and ninety-nine percent perspiration." It's meant as a clever, memorable quote, not an actual formula. It just means that exercise alone doesn't create the conditions for weight loss and nutrition is very important.

Depending on where you are in your weight loss, the balance of importance changes. If you're 200 pounds overweight, you can lose large amounts through nutrition with next to no exercise (although of course exercise is always important for cardiovascular health.) If you're 5 pounds overweight, you probably can't cut enough calories to make much of a deficit, so exercise becomes crucial (but still insufficient without calorie control.)

We all know the key to weight loss is a healthy diet/exercise plan. I've heard numerous times the quote '80/20' - losing weight is 80% what you put in your mouth and 20% what you do physically. What's your opinion?
