I was instructed and have followed religiously NO drinking 30 minutes prior to eating and 30 mins after eating.
Also, I used a timer on my phone. I would wake and drink a protein shake, set my timer for 30 minutes, eat a mushie, set timer for 30 minutes, drink 8 ounces of fluid, set my timer, eat a mushie, set timer....etc. the entire day. It helped me get in 600 calories a day while I was losing. But I think while I was at 2 weeks I was lucky to get 400 calories a day and I would do atleast 2 protein shakes a day. Can you add milk to your shake instead of water ? helps get in some calories.
