I want too start jogging tomorrow but i feel embarrassed--how can i lose weight?

Start with a plan: Congratulations: it is important to start with a plan otherwise you will not have longterm success. Also make sure you get a complete physical, i recommend starting with a personal trainer just for a month, and start with moderate to fast walking and then build. Look at fineonedayatatime on facebook.

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).
