Did you take your measurements before starting your quest? Sometimes the weight loss will slow but we lose inches instead.... and vice-versa.
Make sure to keep yourself hydrated...drink purified water.
Also, when you're walking, throw in some "spurts" along the way. Walk steady for say 5 minutes, then for 30 seconds walk as fast as you can, then walk steady again. Do that for several workouts and see if that helps, it should.
ok ok i just learned this in nutrition class last week !
when you excersice (sp?) do it when your glucose levels are low so then u use the stored sugars ( glucose aka glycogen). when you workout when you have high levels of sugar in you blood ( 30 mins to and 3hr after a meal) you use that before the stored fat for ATP(energy) also are you walking at a normal speed? if so your not bringing up your heart rate ! so walk faster until you find yourself on the edge of "out of breath" when your heart is pumping ! also dont eat at least 3hrs before bed...
i have been seeing rapid results by doing this
-jog 20-30 mins a day
- eating 5 times a day (whatever i want)
- talking Flax seed oil (nasty)
and focusing on the positive results rather than the negative
-let me know how it goes
