My insights after a month and I keep going

Hi, I'll be forty this august, i was 208 last year and lost some weight before my gallbladder surgery last December, 3 weeks after surgery I was 173, well after that I got lazy and ate whatever I liked and I gained back, until a month ago I made a decision to take my Health seriously, so I weighted 182 two weeks ago, now I am 175 and looking forward to be 125 in six months. I'm 5'5" and I work out 5-6 days a week. Also, I am eating 1200-1500. What I have figured out is that you gotta make a decision today and turn that switch to eat the necessary, food to nourish not to enjoy it, because that is the problem when we start to enjoy it that much that we overindulge. So weight loss and to keep it off is about 70% diet, 30% exercise in my opinion. I cut dairy, carbs ( I only eat a piece of sprouted grains bread or a cup or 1/2 of brown rice or a sweet potato only after working out) sugars (including the fake ones, you will forget about sugar cravings soon). I eat 4-8 oz of protein a day, plus 2 boiled eggs, plus protein shake no sugar added. I eat two servings of fruit a day( berries, 1/2 grapefruit, apple, pear only these have less sugar ) I eat all vegetables that I can, when cooking I don't use any oils, I use instead broth and it works. But a spoonful of fish oil a day works so you can have your ration of fats a day. I take a multivitamin and I drink a lot of water, I also divide my meals in 5 small throughout the day, sleep good.
Workouts: I jog/walk 4 miles( now I stopped jogging because knee problems so I focus and other types of exercise) swim laps in the pool, elliptical in the gym, rowing machine in the gym. When I just started I did little but I pushed myself into do more, you gotta read your body, and very important to stretch for at least 10-20 min before and after working out.
Never give up, listen to your body rest, if you failed one day, next day continue until you achieve your goal.
Good luck
