Does it matter what you eat ?

For your health, Hell, yes, it matters.

For weight loss, No, not a bit. You can lose eating anything. The biggest problem with junk food, as related to weight loss, is that you'll be so much hungrier. You can eat a lot more lettuce and apples that you can peanut butter cups and ice cream.

A bunch of people will pick on you for using the word "clean." Some get very personally offended by that word and throw temper tantrums over it, lol.

No it does not, but if you would like to hit your macro and micro targets, you will want to have some whole foods mixed in your diet.

I eat all the foods.

No it makes no difference in weightloss. It will make a difference in your energy levels. The best diet is one you will be able to follow so if an occasional MCD day works for you then do it. Good Luck

Well...

Of course you can eat only McD or BurgerKing or KFC or whatever their names are..

Very basically you lose weight if you burn more, than you eat.

So you also can lose weight by eating 2x 100g chocolate bars a day. But nothing else.

But do you want that?

I see my weightloss as a chance for a new healthy lifestyle.
So junk food only in very restricted doses. Not much sweet stuff and trying to cook myself so I know exactly what I eat.

Even while losing weight your nody should get everything he needs. And that he can certainly not find in McD.

There is actually a very good doku about a guy eating only junk food and what it did to his body. Including lab tests and so on...

^^^ i agree with this. esp about the hunger factor. healthier foods tend to keep you fuller longer than something like ice cream, after which most people have a sugar crash and get hungrier. harder to stay within calories.

The man lost weight and lowered his cholesterol eating at a calorie deficit with balanced macros. He ate beef, chicken, fish, bread, cheese, vegetables,etc... It just all happened to be from McDonalds. I think the point is that food is food, just because it was from a fast food restaurant doesn't make it "junk". It won't make you unhealthy or cause weight gain, the over consumption of it will, just like any food.

It might make a difference for you personally, if it affects how you feel or how easily you can sustain the calorie restriction.

In theory, if you really keep all else equal, it shouldn't make a significant difference (there are slight differences in how much of the total calories from food you actually take on, vs. using up in digestion and so on). However, that's more theoretical than how it works in practice for people, just as most people (anyone not doing an experiment, IMO) don't eat 100% broccoli or 100% bananas or 100% cookies or 100% Big Macs.

no, but yes lol you can eat whatever as long as you don't go over your calories ...

but if you eat junk you will be hungry all the time ... n feel like you're stravin when really you will be. 300-400 calories for 1 slice of pizza ... n still be hungry .. or a HUGE salad with some meat (trukey or whatever) n cheese n dressing ... n you'll be stuffed for hours .... n it may be 300-400 calories.

Nope, it doesn't matter. I proved it several years ago.

Does it make a difference if you eat 1,500 calories at McDonalds or 1,500 calories of clean food when losing weight ? I know, clean food is better for your health, but I'm just asking in terms of losing weight, does it matter if I eat 1,500 calories of burgers or 1,500 calories of salad and apples everyday ?Cause someone actually lost 37 lbs eating only at McDonalds: http://sploid.gizmodo.com/man-loses-37-pounds-by-eating-exclusively-at-mcdonalds-1496972541

I agree with everyone else that purely for weight loss it does not matter. I will however add to this. If you ate 1500 calories of McDonalds I would say that you would probably have a high probability of eventually not sticking to your diet. 1500 calories of fast food is likely to be much less satiating then if you ate fruits, vegetables, lean meats, fiber, etc. While 1500 calories is 1500 calories, you need to think about the likelihood of adhering to your plan as well. If the amount of food you get is going to be insufficient for your appetite then your odds of eating more then 1500 calories increase.

Agree with all this.

That having been said, I don't eat especially "clean" and in fact just ate a gigantic pumpkin cupcake...and I would do it all over again.

I don't think I ever "pick on" anyone, let alone for using the term "clean" for food. However, although I didn't happen to even notice it this time until Kalikel commented, it's true that I think it's an unfortunate and quite silly word to use to describe food. Usually what people mean is "nutrient dense" food, but it gets confusing because some use it to mean food that is not whatever arbitrary thing they've decided people shouldn't eat, like anything containing grains or added sugar or even dairy or saturated fat or the like. It's confusing and relies on the premise that others are eating "unclean" foods, which sounds a bit Levitical for a discussion of nutrition.

The first time I saw the word, I thought it was some fad diet word. I have since come to learn that the definition varies as much as the definition of "moderation." Different people use these words in very different ways. Nine times out of ten, the word "healthy" could be substituted for "clean", but not always.

Lean, white meat is clean to many, but not to vegans. Etc. it does get confusing.

If you've picked on anyone or thrown a temper tantrum, I haven't noticed it. But it happens. Someone says "clean" and the fur starts flying. The mocking begins. You must have noticed this. I think people should be warned.

Alright, I'm posting an opposing opinion here...

It sure does. Fruits and veggies will keep you full for a longer period of time, and you won't experience sugar crashes or vitamin deficiencies.

How is that an opposing opinion? No one said it doesn't matter for satiety--many (including me) said that it probably does. But the question assumed that satiety was not a problem and the calories in question were, in fact, achieved.
