Could My Protocol Stopped Working?

I have watched the Stop Overeating Workshop and have been for years on a diet that consisted mainly flour and sugar 🙁

When I built my protocol two months ago I removed flour and sugar as well as snacking completely and lost a lot of weight but am stalling for three weeks now with no weight loss at all. Here’s my protocol:

Breakfast = Venti size cappuccino (with whole milk)
Lunch = 2 scrambled eggs with smoked salmon, two baked potatoes medium size, venti size cappuccino
Dinner = 1 cup of steamed white rice, 5 oz. of grilled fish, 10 oz. of veggies

What ain’t right?
