Welcome to 3FC
Congratulations on wanting to make changes!
Have a plan. Have goals. We can't just wish the weight away. We can't pretend it will disappear if we aren't actively
doing something about it.
You don't have to change everything all at once, but take a good hard look at your habits about food and movement.
Here are some starting suggestions.
1) Write down everything you eat for a week. Don't change anything... just look at what you're eating. Notice any patterns? Notice what kinds of foods you're eating? AND the quantities? Notice what you're drinking and how much?
2) Find support. You've reached out to 3FC which is amazing! Keep coming back

If you have a support system around you (family/friends/weight loss groups) then reach out to them, as well.
3) Here's where "have a plan" comes in. Start adding in healthy habits. Bulking up on vegetables and fruits for parts of your meals and snacks. Cut out full sugar sodas and juices and start drinking water and/or diet soda. Look for opportunities to take the stairs or to park far from a store you're heading into.
This can seem like a daunting process. But, truthfully, it's worth every step. Cut up your goals into manageable pieces. Don't force yourself to change everything all at once if it seems like too much. Be proud of any and every healthy habit you start building up.
And, most importantly, never... never give up. There may be difficult days, there may be days when we make not-so-great choices, but it doesn't matter. If we keep returning to healthier habits, the weight will come off, and we'll never quit.
You can do this.
Do you have any ideas about what you'd like to do?
