Define junk food. If you're talking about lots of refined sugar / white flour, probably bad. If you're talking more fats and proteins, and you have good genes, you might be fine. IMO vegetables are important for digestive health, but don't really help you lose weight.

I'm surprised you have the energy if you're only eating junk food.

My impression: Weight loss is calories in and calories out (though lots of things affect both sides). It takes a lot more effort to burn calories, so if you want to lose weight, cut calories.

BUT if you are in caloric balance, you're going to do OK if you exercise a lot, even if you eat a lousy diet, up to a point. You still have to have some fruit or veggies, don't guzzle soda, etc., but you can eat burgers and donuts regularly.

Full disclosure: This is probably informed by my bias as a slim, active, middle-aged guy who eats reasonably well but could do better.

Data point: At the 2008 Olympics, Usain Bolt literally ate nothing but Chicken McNuggets and bottled water. He set three world records. (https://olympics.nbcsports.com/2020/04/21/usain-bolt-beijing-olympics-2008-chicken-nuggets/)

Skinny fat is just as bad as fat fat, health wise.

Do you have study to back up your claim or just pure speculation?

There are several. I’m just sick of posting links that people then refute without having read the source. It’s being skinny fat, aka “thin on the outside, fat on the inside,” (TOFI). It’s just as bad as being obese (a percentage of whom, about 30%, are just healthy people who literally are just genetically fat) because it’s all visceral fat, the most active fat. It might even be worse than obesity (seriously, how are you “concerned people” going to “share your concerns” with the right people going forward? I’m worried about you guys.)

I’m seriously sick of providing thoughtful links to be ignored, so here’s a throwaway. https://drhyman.com/blog/2015/07/16/why-skinny-fat-can-be-worse-than-obesity/

OP here, and this makes me so sad. As a result of this thread, as of this weekend, I've upped my routine to 1 hour 15 minutes x five days per week vs. the previous 1-hour x five days per week. Not sure how much of a difference that will make, but I am willing to work harder to continue to eat what I like.

Doesn’t work like that. I’m late 40s and I actually eat pretty healthy and used to only exercise 2 or 3 days a week. Now I work out 5 days and it includes strength training, spinning classes, rowing, running, HIIT classes and it is still not enough. Weight in the mid section cannot be prevented. My weight is only a few pounds more than before and I’m in excellent shape overall, but once you get to your mid to late 40s, unhealthy eating cannot be compensated with an extra 15 min of exercise per day.

+1. I'm early 50's and stopped being able to eat whatever I wanted (butter, red meat, ice cream, cookies, rich desserts, etc) in my late 40's. I run and strength train 1-2 hours a day and thought I could eat whatever I wanted because I never gained weight. The problem was that even though my weight was on the very low end of normal, my cholesterol was through the roof and my skin was bad. I always ate a lot of fruits and vegetables and cooked most of my meals from scratch, so that was not a change I had to make. The change I had to make was to eat less red meat, dairy, chips, and sweets, and to add more whole grains. I did not cut out any foods, but just eat less of the processed foods and more of the good. I used to eat a bag of potato chips for lunch but can't do that anymore.

So much this.

Just wait for perimenopause and you’ll be wishing you changed your diet. Even with same amount of exercise and same amount of food, you will start to gain weight. Really hard to lose it.

No it isn't. Having large/excessive amounts of fatty tissue damages organs, disrupts hormones, reduces lung capacity, strains joints.

Yes, it is. If someone is skinny fat and is thus metabolically unhealthy, they have the exact same issues with poor health that a fat fat person has. There, now you have more people to fat shame - your problem will be trying to figure out which skinny people are skinny fat and thus in need of fat shaming.

“Skinny fat” carries a much much less fat percentage than an obese person. They are not comparable at all. There is no indication that someone who is “skinny Fat” or whatever that even is..has any metabolic problem at all. It just means they aren’t athletic and don’t have exceptional muscle tone, but that isn’t a medical problem

I kinda think you all may be having the wrong conversation here.

OP asked if eating 1800 calories of junk and exercising a bit will have a bad outcome. The answer is yes. And that has nothing to do with BMI and everything to do with nutrition.

The originally quoted OP had it right.
