Will carnation instant breakfast cause weight loss or weight gain?
I tried to do this....I drank one on the way to work and at about 10 am, my stomach would start to hurt and I'd feel nauseous. I don't know if it was just me or not, but I had to stop.
Reply:There's no way to tell with the information you provided. If you eat more calories during the whole day than your body burns, you'll gain weight. If you eat the same amount of calories, you'll maintain your weight. If you eat less calories than your body burns, you will lose weight.
