Let me clarify something from a personal trainer's point of view. When stress, family problem and emotional state of mind is involve during a weight lost means you were not giving your body the calorie amount it is use to. Hence, your system goes into the catabolic state and start to eat your muscle mass to sustain.
During this time the weight you have lost was muscle mass not the fat or burn calories. Muscle mass weight more than fat. I recommend get back to eating to increase the calories from high protein and complex carb from the veggies. Start by taking the amount of calories you normally intake for the day and divide it. The largest meal should be breakfast containing 60% carbs from oatmeal, fruit and whole grain bread, 20% fat from good source and finally 20% protein from egg whites. Then start on a full body workout three days a week. do not do too much cardio, you want to rebuild your muscle mass.
