Weight loss is extremely well understood now and very well documented.
It's energy balance. Nothing more. Going low carb doesn't mean
anything for fat loss. You can go low protein, carb, or fat and still lose weight. The reasoning for lowering one group over another will depend on your goals.
Generally, it's wise to go for a high protein, high carb, low fat diet when trying to cut body fat down. Reason being:
- Protein builds muscle. The notion of "I don't want to look like a thumb" is preposterous, because that's not going to happen easily. You'll likely need steroids and a damned near perfect routine + diet for 4+ years, with lucky genetics to boot. Those people do not represent a couple years of muscle building - not a single one of them. You'll likely want to build muscle for a year or two at least, male or female. You need protein for that, so high protein is a good idea.
- Carbs are your main energy source. Simply put, with a carb deficit you're going to feel tired as fuck. That's going to severely impact exercise. If you want to go the keto route, you're free to do so, just understand that is has ZERO impact on the effectiveness of weight loss. That is a proven, observational fact. Once ketogenesis kicks in, you should start to feel MUCH better, so you'll have to suffer with some major energy loss for a while before that happens. I personally hated it when I tried it.
- Fat is responsible for a lot, typically mental & hormonal functions. This is the one macronutrient you can cut back fairly large on with minimal impact, though. An average guy can get away with 20g of fat per day without side effects. That's why many athletes choose to go low fat when they're cutting body fat down.
If any of you are interested in adopting a fitness lifestyle, I cannot recommend it enough. The energy and mental clarity is stronger than taking an adderall on one of your rough days, but it's consistent. You just feel like your body is operating like it should. I sometimes tell people I feel like I have the energy of a little kid again.
The r/fitness subreddit can be pretty toxic (especially the mods), but their wiki is a fantastic resource, and very easy to follow. It will give you everything you need to know. Their weekly threads are good for getting advice, but I wouldn't bother making a post. Almost all of them are blocked. I think it was honestly inevitable with it being a default sub. Before the mods got ban heavy we saw "why am I not losing weight" posts every hour that could be answered by reading the wiki.
I'd also highly recommend Buff Dudes and Jeff Nippard on Youtube. Very entertaining videos, and they back up what they talk about with research - not just results.
Lastly, I wanna shout out cronometer. It's helpful for tracking your macronutrients and micronutrients. You don't have to worry about micronutrients for your fat loss, but it's huge for overall health. So, your skin, overall mood, sleep, joint pain, and many, many other functions are heavily impacted by the micronutrients. I waited a good year before I focused on them.
