I want to get in shape, my biggest issues is my body fat(my weight by extension but I want to be slimmer). I think what I struggle with most is my eating habits because I get a fair amount of exercise just walking every day, even on the days where I don't then later actually go to the gym.
Portion control is probably where you want to start. I have a cheat because I'm still a smoker, and I get the appetite suppressant benefit of it. (Not recommending you take up smoking for weight loss though.) So I don't suffer as much from hunger eating less.
Or rather than portion control, you could try doing just two big meals a day. But they need to be good, wholesome meals that hit all the macros in balanced proportions.
Also finding snacking vegetables you don't hate. Vegetables don't have much in the way of calories or macros, but they have plenty of micronutrients AND they fill you up. Carrots and spinach are my go-tos right now because they're veggies I can tolerate raw.
Another trick is just to chew your food twice as long as you are now. The act of chewing signals your body to release leptin, a hormone that tells your body its full. More chewing = more leptin = getting satiated faster. This is a really hard one for me. When I'm ready to eat, I want to fucking EAT. So slowing down to masticate my food more thoroughly is tough.
It also comes down to body type. Are you an ectomorph, an endomorph or a mesomorph? As an ectomorph, my metabolism is pretty high by default. As such, I haven't followed a super rigorous nutrition plan, but between my workout intensity and the quality of food I'm eating, I'm losing weight pretty consistently. I'm still getting a daily dose of sugar, probably about 80g a week total, and enjoying carbs at least twice a day, which if you take advice from fitness experts is a no-no. And yet I'm still consistently dropping weight because of MY body type. it works because my metabolism can compensate. If you're an endomorph though, with a slower metabolism, you may have to exercise way more discipline in your dieting.
And let's also be realistic: dropping more than 20 pounds in 3 months is pretty extreme if you're not horrendously overweight already. I've managed around that, and that comes out to 1.6 pnds a week. Often our desire to lose weight outstrips the realities of time and metabolism. As long as you're dropping weight consistently, even if it's not a huge drop, you're on the right path and just need to put in the time. I'd say around August I committed to getting a six pack and watching the months tick by without getting it has taken a toll on my motivation. But because I'm in for the long haul, as long as it takes, and I didn't sort out my nutrition until October, I view any weight loss as good weight loss and signs of improvement. I don't even want or need to be beach ready by summer; what is beach ready anyways? It's generally an unsustainable standard of physique that the people pushing it have to go to extremes to achieve. 48 or 72 hour fasts, intentional dehydration, taking all their photos after their workout so they've got a good pump going......all these are temporary illusions of shredness for the most part.
Consider also that people who are shredded and are coaching you to reach shred levels......had to get there first. They didn't just magically in one month go from 22% body fat to 10%. They had to work their way down just like everyone else, and instead of now playing the weight loss game, they're playing the
maintenance game. Which according to a lot of sources I've read, maintaining is way easier and more flexible than slimming down.
So don't let the time frame stress you out. You've got a real life with actual responsibilities and don't have the luxury of making working out your job and nutrition your life, both of which are true for the people pitching many weight loss plans. So your results will be slower than someone who can dedicate all their energy to working out, and all their mental space to a rock solid nutrition plan. For them, being fit = money. That's their extra motivation to watch what they eat, get in all their workouts, and try crazy diets and metabolic hacks to get as shredded as possible as fast as possible. The rest of us? We have to rely on different sources of motivation and our timetables are vastly different. You CAN try to live the lifestyle they do, and it's doable. But probably you just run the risk of not being able to live up to that standard, getting demoralized and falling off the wagon.
If don't let the time required bother you, you will see consistent improvement over time. And as long as you don't plateau (which usually comes down to nutrition), you will continue to slim down until you've burned off most of your excess body fat and can go in to maintenance mode.
TLDR: You can get to where the fitness models are. It's just going to take more time, and more discipline, on your part.
