Curious!

I've done it. That was the first time I concentrated on weight loss, about 10 years ago. Did a lot of running, a lot of lifting, but paid no attention to my diet at all other than ensuring I got enough macros, and went from about 220 (my heaviest ever) to about 180 at my lowest. I didn't look too bad, but I could have looked better had I dieted as well.

Right now I'm about 170, which is a good weight for me. I couldn't have gotten here without dieting.

My brother does all sorts of gym and cardio and strenght exercises. He is overweight and has never lost weight because he doesnot cares about diet. it has been 10 years to it.

Well, if you can burn 500 calories or so consistently (unless you're fine with slower weight loss rate) AND if working out doesn't ramp up your appetite I don't see a problem. If I were you I would still log the food. You don't have to change how you eat, but you need the record to see if you're creating the deficit you want or not. If you notice that your diet is consistently using up all the calories you're generating through activity, it's time for a new plan. Note that diet doesn't need to change too much if you were thin at some point, the types of food can stay the same but how much and how often can be tweaked to your liking.

I'd agree with others here. I have been a regular runner for 20 years and was a little overweight for the duration. It was only when I cut back on eating that I started to lose weight. Exercise is important for health, but it does make you hungry, and, if you don't know the calorie count of food, it's easy to "reward" the exercise with food that contain more energy than you've burned.

Guess it depends on how much exercising you'll do compared to what you are eating.

I've never been able to! I've been active and fit (though overweight) almost my entire adult life! I can run for an hour at a time, I play competitive soccer once a week, I do cardio and lifting workouts at home--I exercise 6 times a week! Yet--I have just watched my weight slowly creep up....it's been disheartening honestly. Since Jan 1 I've been CICO and very mindful of what I eat and portions...I'm down 8 lbs and have momentum....I would say to find a way of eating that isn't so restrictive that you feel like you can't live with it but that will help you reach your goals!

I've never been able to not care a whim about what I was eating, unless my activity was absolutely off the charts.

That being said, until I got the dreaded desk job, I didn't have to really watch or count calories - cut down on the fast food or soda or candy bars and I'd be good to go. Going from active jobs to sitting on my butt all day, however, was a complete game changer, and I didn't realize it until FAR too late.

Now, with my current exercise program, I don't feel like I'm "dieting" but I still have to count my calories (still have weight to lose) but I workout enough that I can fit some crazy things into my daily calorie allotment (as in, a large fast food meal without the soda can fit into my day and still have 2 smaller-than-normal meals). Once I finally reach my "goal" I will probably relax on the calorie counting, but I will probably have adjusted to the eating by then, too.

Without the added exercise, yes, I'm going to feel like I'm dieting, and will likely be miserable in that department.

I first started exercising for a pe credit for my degree. I was slowly losing weight, but it wasn't until wk 3 wheb the instructor pointed us to myfitnesspal for the wks assignment that I put 2 and 2 together. Diet With exercise propelled me into my wright loss journey where i lost 50 lbs!

When I was eighteen, I took a year off before college and worked on goat and sheep dairy farms. I went from being quite sedentary to moving around a lot every day, milking sheep twice per day, cutting grass under the electric fence, etc. I was vegetarian at the time and I think I ate fairly healthily, but all throughout high school I was a chunky 120 lbs (I'm 5" tall). When I went back home for Christmas, I found I had lost 20 lbs. I was right around 100 lbs. People kept commenting on how I had lost all this weight and looked great, but because I had been fairly unaware of my weight throughout high school it didn't really affect me that much I'm 152 lbs now and would be thrilled if I somehow lost 20 lbs without realizing it. (Though I wouldn't actually like it to happen because probably it would mean I was horribly sick in some way and that would be bad). The moral of this story.... Yes, it is possible, but you have to exercise A LOT. Like changing your entire life style. It's like the Amish diet I heard about once: eat whatever you want and work in the fields for 16-18 hours per day.
