I'm currently at 193lbs from being 210lbs-ish last year, but I wanna be in the 150's by this mid summer, so my vote went for 30+
I used to be way heavier though at 320lbs. I'll be turning 29 next month, so perhaps it's just easier to lose weight at this age than it is for some of you more mature slappers, but this is what I've been doing...
Back in early summer 2019 I cut sugar from my diet besides natural sugars and also started calorie counting. As for working out I would walk 4MPH for one hour and I started to do some beginner weight lifting, I would do this about 4 or 5 times a week. I also drank a ton of water daily, like a gallon or at least close to it. After being consistent for a bit I dropped down to 220lbs-ish by early 2020...
So then in 2020 when shit hit the fan, I only lost about 10lbs and plateaued for the entire year despite still working out and even skating again for the first time in almost a decade. I blew it because despite keeping active I was no longer counting calories and casually consuming sugary snacks again. It sucks, but at least I maintained my weight and no progress was exactly lost.
Since the beginning of this year I'm back to calorie counting and cut down on sugar but I didn't cut it out completely this time though, for example if I want a sandwich or something and it only has like 3 grams of added sugar or so I'll let it slide for the day. At worst I'll consume a few grams but try to keep it under 10 and not make it a daily habit. For exercise I'm doing heavier weight lifting now and only walking 4MPH for half an hour afterwards just for a little cardio. I'm only working out 4 days a week but would like to skate during the other days once the weather around here clears up.
Anyways, that's pretty much what I've been up to in order to try being healthy again. I've never tried any gimmicks or trends, just simple exercise, a healthier diet and staying hydrated. I'm also laying off salty foods sometimes but not as drastically as sugar.
As for food, this is what I regularly eat:
Eggs
Tuna
Turkey Bacon
Skinless Chicken Breast
Oatmeal
Beans
White Rice
Fruits and Veggies
Chorizo
Sugar Free Jello
Potatoes
Peanut Butter or Bologna Sandwiches...
And I'll usually allow myself a cheat day on Fridays, but I just try not to go overboard.
So yeah, that's about it, and as for why I was so heavy the TLDR version is I tore my ACL back in 2010, reinjured it in 2011, stopped skating, finally got the surgery in 2013, fell into depression and picked up bad eating habits from my Mexican family while sitting at home.
Good luck.
