Congrats on the weight loss but why do something as gross as that?
With a good, tasty, hearty diet you could have lost that weight in half the time.
Oatmeal is a wonderful diet food as long as you don't use sugar. If you must have sweetener the I guess splenda is okay but I'd recommend staying away from artificial sweeteners.
Yogurt also is a great diet food. It's been shown that dairy products like milk and yogurt are not only very healthy for you, they keep you full longer and help with losing fat, especially from the mid-section.
Cottage cheese is a good food to incorpotate into a healthy diet.
And why CONDENSED milk? If your worried about fat then use skim but that fat in 1% or even 2% can be healthy for your body. Little tip: I always alternate between skim an 1% or 2%. I drink upwards of 5 gallons of milk a week so drinking only 2% would be alot of fat.
