I can't lose weight despite i managed to lower high carbohydrate foods.

That's a start: If you can distribute your food including slow carbs like quinoa, amaranth, and buckwheat groats soaked for 8 hours, rinsed and cooked for 15 minutes with vegetables, berries, beans, and fish into 6 small equal meals followed by 10 minutes of movement like walking after each meal, stress reduction, and a good night sleep weight loss happens.
