Yes... exactly!
They key to losing weight and being healthy is a healthy diet and exercise!... the first thing you do is go into the fridge and throw out the butter tub, cheese, mayo jar, ice cream, and whole milk... replace the whole milk with skim milk, then go to the pantry and throw out the peanut butter jar and the cookies... all of these "so called" foods are very high in fat!
Your body has to do very little to fat in the digestion process and it goes straight to being body fat! There's an enzyme in body fat called Leptin, when you burn body fat your Leptin level drops sending a signal to your brain that you are hungry even though you may not need to eat... it is a built self preservation device and is the main reason overweight/obese people feel like they need to eat even though they don't!!!
A low fat diet rich in raw fruit, vegetables, and very lean meat (mainly skinless baked poultry) and low fat soups will make a healthier fitter you!
