last 10 are the hardest to lose...

If the last 10lbs are the hardest to lose, than try to lose 20lbs and quit halfway through!

I have found that especially during the summer it helps to have some healthy sweet treats around that are not horrible for you, for instance skinny cow ice creams, and lindt 70% dark chocolate. It helps cure your cravings and saves you from gorging on sweets when you are around them, you need to allow yourself somethings in moderation to be able to maintain and keep losing weight, As for parties, I am starting to bring my own food, like healthier options. I usually take veggie burgers, baked chips and fruit. That way you can eat what you have brought and it won't be so hard with all the other food around. Atleast you have provided some healthy options for yourself. Hope this helps

The discipline is easy to solve - if you bite it write it! Anything you eat enter into your fitnesspal and track. Tracking what you eat is the key to weight loss. When we mentally track things we "generally" remember them all, but then we do forget some and the things that we tend to "forget" are generally the more calorific, these forgotten calories are the ones that will be hindering our weight loss. Use the app, stay within your alloted calories a day and you'll soon shift the 10lbs.

Youre right, they are the hardest to lose! I started out in January and the pounds melted off. Now that I'm down 40lbs, I don't burn as many calories when I work out so I'm trying to add more intense stuff. I was walking at first, then started jogging, broke my toe and foot, then started biking! It seems like I'm losing a little bit more with the biking and I have a HRM and I get all sweaty again like I used to when I walked, so I know I'm working at it harder.
I also have to be more careful with what I eat since my body needs fewer calories to maintain. It's actually just over 1200 now and that's a pain for sure. I've had the same probs with dinner parties, bridal showers, weddings, birthdays, etc. What I've learned to do is plan ahead. If it's potluck, I take something I KNOW I can eat and then add a few other things provided but as far as size-wise, I keep the portions small, usually about 1/2 cup. We need to remember that we should be eating to live, not living to eat. In my family anyway, most get togethers focus around food! It does make it difficult but you can learn how to cope.
If you love ice cream, try some of the Skinny Cow Ice cream sandwiches, etc. I think they have about 100-120cals each. Schwanns, if you have access to them, they have 60-90 calorie orange cream and rasp cream bars (big sized too) and fudge bars. I cannot have regular fat filled, sugar filled ice cream or treats in my house or I'll eat it.
Also, eat some sort of protein, bar or boiled egg whites (17 cals each) before you go to events and make sure you have at least a cup of water before you start grazing. It does make a difference.
And,, last but not least, you KNOW you want this, you have the power to say no, even if it's one 'snack' at a time. Everytime you say NO to something you know you shouldn't be eating, you become even stronger.
YOU can do this! Good luck!
