Here goes nothing

Welcome to MFP! This is a great site with tons of helpful, friendly people. You CAN do it! Since you asked - a few quick bits of advice, which you may or may not already know/follow. (When someone asks for general advice, it's hard to know what their starting point is or where they are coming from... so pardon me if these seem a bit "basic")

-It looks like you don't have much weight to lose (based on your profile) - don't expect it to come off quickly! The less you have to lose, the slower it is. You should have a pretty low goal as far as loss per week (1/2 to 1 lb) - if you lose more, great - but it's not good to have too high if a deficit if you don't have much to lose.

-Drink enough water! This is one of the biggest factors for me - when I don't drink enough, it's much harder to lose weight, even if I exercise and eat right.

-As far as what foods to avoid - the more procesed foods you avoid, the better. Fresh, homemade foods are ALWAYS better for you - not only do you control exactly what goes in it (therefore avoiding the excess sugar/sodium/bad fats/etc. in processed foods) but you also avoid some of the preservatives/chemicals that many people think can be harmful in the long run. If you eat mostly from these foods, you'll be just fine: Lean meats, fish, fresh fruits/veggies (starchier veggies are okay in moderation, especially the healthier ones like sweet potatoes, winter squash, peas), legumes, eggs, dairy, lighly processed whole grains (oatmeal, quinoa, barley,etc.), nuts/seeds and healthy fats (olive oil), etc.

-Learn to read food labels - You CAN be healthy and buy some processed/canned/etc. food - but you have to learn to buy the lower-sodium, no-sugar added, etc. options when they're available. Generally the fewer ingredients the better. Ex. buying peanut butter that is made only from peanuts, rather than having extra salt, sugar and oils added in.

Good luck!! You can do it
