There is a bit of stress going on today. With 40+ hours work weeks and fast food diets. There is just not a pill that is going to make quick weightloss happen.
The extra weight did not magically appear overnight and it is probable not going away overnight.
The first thing you will need to do is simple really. Just stay away from junk food. Mainly foods that do not have a health benefit.
Foods that are high in sugar are the main things. Namely goodies, munchies or what ever cute name you have for them.
Sodium is not good for you in high doses. Sodium retains water and can make you heavier than you really are.
Adjust your eating habits from three times a day to five times. You are probable thinking how will I lose weight if I eat more often.
The fact is you need to have smaller portions more frequently. This eliminates the between meal snacking and will also kick the metabolism into high gear.
It will also provide the metabolism with the fuel it needs to burn calories, because it does take fuel to burn stored up calories. Starvation diets do not work for this very reason.
Start a moderate exercise program. Start slow and ad time and intensity as needed.
Playing tennis is okay if you are energetic but if you want a more casual exercise program that is fine also.
Go for a nice brisk walk or park an exercise bike in front of the T.V., watch your favorite show while you exercise, multitask.
There is no pill that is going to make the weight just go away. But if you stay consistent and keep your focus on the end result you will slim down in no time.
