How can i lose weight?

You can!: Start by keeping a food diary for a week. Write down every thing you put in your mouth for a week, the time you eat, how much you ate, & be honest. Then after the week, analyze it, & see what you can do without, what you can cut back & what you can eat differently & then do a week of the same. Count the calories and see the difference. 500 cal less/day equals 26 # loss per year. + exeercise!

Diet and exercise: The goal is to burn more calories than you consume. Watch your diet; eliminate junk food and don't over-eat. Consider liquids as well; soda, alcohol, etc. Contains lots of calories. Exercise multiple times a week. If you find an activity you really enjoy you'll be more likely to engage in that activity. Avoid fad diets that could prevent you from getting adequate nutrition. Make healthy choices!

Nutrient dense foods: Eat foods that are nutrient dense (like meat, fish, poultry, eggs, cheese, low starch vegatables and water) avoid foods that are not nutrient dense (like starches and sugars, including fruit) nutrient dense foods will increase your basal metabolic rate. On the other hand, starches and sugars impair thyroid metabolism via affects on your liver (which helps activate thyroid hormone).
