No exercise needed for weight loss?

Exercise is certainly not worse for weight loss, but you can lose weight without exercising. It's all about calories in vs calories out, if you're in a calorie deficit without exercise then you'll lose weight, if you're in a calorie deficit while exercising, you'll lose weight. If you're in a calorie surplus in either situation then you'll gain weight

To lose weight you need a calorie deficit. You can create a calorie deficit:

1. Through diet alone
2. Through exercise alone
3. Through a combination of diet and exercise

Most people opt for a combination of diet and exercise as it doesn't require the large time commitment devoted to exercise of approach 2 and allows for more food to be consumed than approach 1.

Exercise is not mandatory for weightloss. Due to some medical issues, I am unable to exercise at this time... but with calorie restriction I have lost almost 16 lbs in 8 weeks. I hope to eventually be able to add exercise into my habits, simply because exercise IS mandatory for optimal health... and I want to not only be thinner, but healthy as well.

it's not "Mandatory" .. no.. as long as the math adds up.

but the idea that not exercising is better than exercises is ridiculous simply because of the math.. ( outside of medical reasons). if helps to created a deficit that's all that REALLY matters, but as stated, easier to created a deficit with you are moving even just a bit.

You should stop listening to whatever idiots you're taking weight loss advice from. How would exercising make weight loss harder? That makes no sense.

Exercise isn't completely unnecessary. It's beneficial for both weight loss and general health. However, it's not a requirement if you're unable to do it. I personally think being too lazy to exercise is a sorry excuse, but that's just my opinion. If you don't want to exercise, don't, but you'll need to eat less in order to lose weight than you would if you were exercising.

I don't know what 'people' you're listening to, but you need to find replacements! Or perhaps become a better listener. LOL
Yes, exercise is not necessary for weight loss. And yes, unlimited free eating simply because one exercised will kill your potential deficit and impede weight loss or even result in gain. But where did you get this idea that exercise makes things worse?
In a perfect world one would address an overly large body mass with a multi pronged approach. First, there's diet. The total number of calories consumed by the day or by the week must be smaller than the amount of calories expended by that same measure. This is simply the law of thermodynamics at work. There's no 'work around' or cheat for this. Second there's exercise. Raising ones daily TDEE through exercise allows for larger deficits. It can make eating at a deficit easier. Moving more in a variety of ways just makes bodies feel better over time as well. Cardiovascular health improves. Muscle memory leads to greater mastery. Balance and motor skills are more fully developed. Mental health improvements ensue that directly impact sleep, resilience, delayed gratification, and the immune system. None of these in and of themselves lead directly to weight loss, but they will help maintain your deficits as you lose body mass because you are able to work harder, faster, longer as time goes on. A third area many fail to recognize would be rest and sleep which are so important for regulating the hormones associated with hunger, satiety and fat storage. Well rested bodies are more efficient bodies. Fourthly there's nutrition. Not just the calories we touched on above but the detailed nutrient content of those calories. That's too big to go into here. And it's not necessary to simply lose the excess weight; it is more important for keeping it off long term and enjoying optimal health.
I personally feel folks need to get to a point where they are integrating all of these details for optimal good health. But I've listed them in order of importance. You can just lose weight with the first or a combination of the first & second. The people who stop there, however, are the same people who probably ultimately regain in my opinion.

I think it may depend who you're hearing this from and what the particular circumstances are... for instance, someone who has Chronic Fatigue Syndrome may be worse off from exercising because it sets them back healthwise. Someone who is severely out of shape and severely overweight may have a tendency to "overdo" and lay themselves up for several days.
But for the average person - increasing cardiovascular health, increasing muscle which is metabolically efficient than fat... these are all good things! Start off slow and increase your activity level.

In my mind, exercise is not required for weight loss is true. Exercise being worse for weight loss however is false.

All I know is that my normal amount of calories is too few to allow for beer. If I run I can have a beer. Running = Winning.

I lost a lot of weight by focusing exclusively on diet. The sum total of my exercise was shoveling a bit of snow every couple of weeks for a month or so and then a stroll once a day after winter. I found it easier to use my mental resources to focus on fixing my diet, than trying to do that AND focus on working out. One thing at a time worked for me, or I just would have exhausted myself and given up by trying to change too many things at once.

Now, after I lost the weight, gym membership was my reward for reaching target, so I could work on cardio fitness and muscle tone.
