One way I've been losing weight is by consuming more protein and less carbs. It has worked so far. But every now and then I get a upset stomach. It usually hppens after I drink my protein shake for breakfast. The protein shake is GNC brand 100% chocolayte flavor Whey Protein mixed with skim milk. Lots of protein very little fat and carbs. Tastes good. But could this be causing my upset stomach? I ask because when this happens I eat more carbs the following day and there is no upset stomach. Could it be that even though I am losing weight using this method I need to consume more carbs? Perhaps I should go every other day switching between carbs and protein.
Any suggestions, answers are welcomed and needed.
