tab23 is right... small changes can make a big difference in the long run.
At the end of the day it all comes down to making good choices about we eat...
Choose whole foods like fruits, veggies, nuts & lean proteins you'll never need to think about dieting ever again. Choose processed foods & sugars and you'll deal with weight issues forever.
Some tips that helped me:
-Try eating 5-6 small meals a day (basically every 2-3 hours)... That way you're never starving and you don't need to over eat since you'll be eating again in just a couple hours.
-Always eat fresh & avoid processed crap (anything that comes in a bag, box or can with a long shelf life). Someone one said to me "the longer the food's shelf life, the shorter yours is". wise words.
-Reward yourself with a "cheat" meal once a week. This will keep you from feeling deprived of your favorite things.
-Drink water. So many people chug down sugars all day not even realizing their packing on pounds just by drinking
Hope this helps!! & Good Luck on your journey!!
