-Do cardio.
-Eat veggies but don't overboard (if it's mostly water and fiber you have to plan accordingly so you don't kill your appetite). Pick some higher calorie dense type like legumes (peas, beans), starchy root vegetables (like potatoes), sweet peppers just track the cals.
-Broccoli is still a staple for me though.
-You could use fresh squeezed fruit juice (calorie dense) to your advantage.
-Having a big meal at night before bed sometimes stimulates appetite (include carbs in that last meal).
-Chew sugar-free gum before a meal....the brain is fooled into appetite stimulation even without the sugar rush.
-supplement with probiotics to aid digestion and nutrient absorption which will prime you for the next meal.
-Give yourself time to adjust to the cals. Move up in cals slowly.
