I've found over the years, that it's not so much that people don't know what to do to lose weight, but it's more of an issue of IMPLEMENTING those healthier habits, and sticking to them.
We all know what foods are good and what foods aren't. Fresh fruits and veggies, lean meats, fish, whole grains get 2 thumbs up. Limit your refined carbs, such as white breads, cookies, cakes, etc. Decrease your soda supply, even if it's diet. Get more water in you (even Crystal Light, Wyler's Light, decaff tea <with sweetener, no sugar>, all count towards your water intake).
Move more...even if just walking. You can get some really great Walk Away the Pounds videos on ebay for cheap, and you don't even have to leave your home to do your walking in these colder/wet Ohio months.
But see, most of these things you alreay know, I'm sure. It's having the determination, willpower, and drive to actually DO them.
Don't think I'm coming down hard on ya, I'm not. I'm speaking, unfortunately, from 7 years of experience of fighting the same thing. I KNOW what to do, but it's easier to be lazy and just eat what I want.
I've found that eating healthier doesn't have to necessarily be expensive either. I buy the canned (no sodium only) and frozen veggies...and same with fruits (light syrup & rinse well). It cuts costs dramatically, instead of buying the fresh, and you still DO get the nutrients.
Try googling "quick healthy meals" or "cheap healthy meals", and you'll get a ton of ideas that way, for new recipes. Chicken is a GREAT lean protein...and there's TONS of ways to fix it so that you don't get bored. (Stirfry, baked, grilled, in casseroles, etc.)
Keep in mind, too, that even buying more fruits and veggies, even if fresh, that if you stop buying the crappy foods (chips, cakes/cookies, ice creams, pizza, etc.), you're actually going to come closer to breaking even, or spending slightly more or less depending on your family's tastes, likes/dislikes.
Another tip...shop at places like Aldi's or Save A Lot. I do the majority of my shopping at Save A Lot and for a family of 4, I can spend, on average, about $35-50 per week on healthy meals there. I'm a huge fan of crock pot meals...throw it all together and let it cook all day.
Weight loss doesn't have to be expensive...I think we convince ourselves that it is, so that it gives us an "out" so we don't have to attempt it. I'm guilty of that a lot!!! This month I have really resolved to get fit, though.
I'm in the Stark County area, and was a patient of Aultman Hospital's physical therapy department. Once you've been a patient there for PT, you can become a member of their gym for only $30 a month. There's no contracts, no yearly commitment, you can go month to month, and that price includes your spouse! My husband spent a lot of time traveling the past year and packed on 20 lbs. So we've decided to go to the gym together, an hour each time, 2 days a week, then I'll go a 3rd day, by myself. I have more to lose than him, lol.
Another thing is if you want to count your calories and such, www.fitday.com is an awesome, FREE website. It has thousands of foods already in storage, with the nutritional information already stored. You just enter what you've eaten for the day, and it calculates everything for you. You can even track your exercise on there, and it has a journal area, for you to write your thoughts, experiences down.
I hope this has helped and I'm sure you'll get tons of replies on this. Having an accountability partner can help too. Someone to check in with you and say, "hey what'd you eat today", or "did you walk?". Good luck with your weight loss journey!
