A lot of people who are sick end up losing weight due to a lack of appetite.
Couple that with the fact that many people limit what they eat to just soup which is relatively low in calories (200-300 for 1 can) and you have easy weight loss.
But why would you want to make yourself sick to lose weight?
Why not realize that you have the willpower to do it yourself and you don't need any crutches to make it happen.
You just need to take it a day at a time...make small changes.
First work on changing breakfast..make it a bit healthier, a bit lower in calories...then when that becomes habitual, move onto lunch..then dinner...making incremental changes makes a complete diet overhaul seem more manageable.
If you want to lose some weight, just get used to filling yourself up with not only soup, but vegetables/salads, as well as lean meats and some fruits/nuts.
Other foods to consider are: Oatmeal, yogurt, no
fat cottage cheese and brown rice.
