you need carbs in the morning and pre and post workout , a good meal replacement in between your breakfast and lunch and btween lunch and dinner would be great , only veggies with your other meals no starchy carbs , you need to incorporate some protein with that oatmeal in the morning as well , other than that ditch any nuts , snacks , drinks , juice , milk , cheese , bread , rice , and pasta. if you arent going to use a meal replacement some tuna and 2 rice cakes would be a perfect replacement , you want about 250 calories no more. if your serious about losing weight you need to be consistent to see what will make your body change then make adjustments from there. you make your diet sound effective but i know from experience that juice and nuts and any little snacks however small can add up 3-400 calories which could very well put you at maintenance or even into a caloric surplus
