off, keep it off, and learn how to change their lifestyle? They are being given a gift of a longer life. That should be worth a little "run until you puke" (as long as that isn't followed by starvation or a whole pizza) The fastest way to lose weight is by running. (It helps to be taught proper stretching and form to reduce the chances of injury.)
Diet pills and tricks don't work. I've discussed "weight loss" before. Here are my tips:
See a physician first. Know what your goal should be based on your gender, height and health. Be aware of what is "Normal Range" and considered a "Healthy Weight" for you. Aim for that number.
Take measurements. If you don't lose weight, you might lose inches as you get in better shape. That counts. It's not only about the weight. It's about overall health. A pound of muscle and a pound of fat are still a pound, but a pound of muscle looks smaller on you, which is why the inches are important.
You did not gain weight overnight. You will NOT lose it overnight, either. It will take TIME, and a committment to an overhaul in "Lifestyle." Make realistic goals, and reward yourself weekly for small/any gains towards your goal (but, not with food items.)
Find a buddy who is about the size you are, likes the same exercise you do, and wants to lose about the same amount of weight. Make regular appointments to get together to exercise so that you don't shirk it.
Environment. If you don't buy it, and it's not in the house, you can't eat it. If you live with other people who do not want to change their bad habits, buy your own food, and don't eat theirs. This takes pre-planning and discipline.
Impulse control and Deprivation. You are in charge of what you put in your mouth, and nobody else. You really DON'T have to have a slice of cake at every office party. "No, thank you" really SHOULD be enough. Be clear.
Don't deprive yourself. Eliminate "bad" foods one at a time if you have to. Don't give up something you love forever. Just be aware of portion control.
Replace foods you gave up with things you've never tried before. I've discovered how much I like Quinoa and didn't even know it existed before I gave up trans fats.
If you are going to eliminate anything? Eliminate TRANS FATS. closely followed by: hydrogenated anything, saturated anything, and anything with more than 3g fat.
Do NOT starve yourself! Use portion control, but eat MORE often if you are exercising, not less. (I eat six times a day, but they are an ACTUAL "serving" and no more.)
I measure portions. I know what an actual "serving" is for one person. I don't go over that.
I know it works. How? I went from being 5'5" and 196 lbs. to and 129 lbs. without ever being hungry, feeling deprived, or sorry that I started eating correctly and exercising regularly. How long did it take? five years.
Why? The were a few reasons.
1. Because I didn't focus on weight loss. Then again, I wasn't on a television show where my team was counting on my overall weight loss for the week. I focused on slowly changing my lifestyle in ways I knew would stick first. That's smarter.
2. The first three years I lied to myself. I talked myself into keeping some bad habits, and justified them. For example, I would reward myself for lap swimming by eating at a fast food restaurant, figuring one would cancel the other out. (uh-- nope.)
3. The fourth year I focused on strength more than on weight loss. I worked out a lot, but I didn't reeeeaaallly change my eating habits. (I just told myself I did.)
4. Although it took me five years to get here? It actually took me a year. Why? I stopped lying to myself, learned about what I needed to do, and used the sense in my head to get there. I made realistic goals I could stick with, and decided that this was a BENEFIT to me, and not a detriment for me to hate. Now? I feel like crap if I eat badly. I feel like I've missed out if I didn't at least get in some cardio.
5. I deliberately found a job where I am not sedentary as part of my committment to health.
Weight loss really is a lifestyle change that you can stick with. A goal is a dream with a deadline. Make it realistic. Focus on "Overall Health" and the weight loss will follow.
Hope that helps!
