some time we considered that just to avoid ourselves from eating helps us in reducing weight but we eat something to live anyway. we need to see what we eat is it full of fats, carbs or proteins and other important thing is or we taking enough fibers or not. Finally our Muscles mass quantity of water level and bone density also count all these can be assessed by weight, height and type of physique. hope it will help.....

The type of diet program matters on your problem. If the program your using doesn't work there are a lot of program to try  in diet that probably suited to you like sugar smart diet.  This program or plan focus on inhibition or reduce your sugar intake that found in process food and fruits that content high sugar. Minimal sugar could help reduce fats and loss weight. This sugar smart diet plan requires days before to get a result  in4 stages and guaranteed.  

In the beginning you know your weight and your height and your age

So I can see how much calories you need per day

2. You ordination drinking water equivalent to cups water or3 liters of water spread over the day given the importance of water to help the body processes

3. does not have to lose weight through diets, food only, but you have to exercise some aerobic exercise a total of minutes per week distributed among the running, swimming and biking and skipping rope

4. Reduce the proportion of fat to eat and have provided the malediction proteins in your diet because the protein strong catalyst for the flesh, do not save fat

5. vitamins and minerals have a key role in weight loss more than Alkhaddraruat eating fruits that contain iron and zinc due to their importance in preventing oxidant food and burn fat

6. more than green tea, ginger and cinnamon and mint because they have incentives to burn fat

7. diet and sports is different from her body and portability from one person to another

It seems you do not drink  an adequate amount of water. You need at least  3 liters a day.
