I'm doing my 2 week preop diet, this first week is HMR shakes and entrees, I'm having a hell of a time eating this food, has anyone else had to do this diet? Well, I'm wondering I'm allowed 2 entrees a day and unlimited fruits and veggies, I was thinking I would do a 4oz chicken breast or broiled cod in place of my meal. Do you think this is ok? The entrees have 200-250cal in each so I would be consuming less calories than the meals and the chicken/fish is 110ish calories....any advise??

I would speak with your doctor regarding not just cals but carb/protein/fat levels. My doctor put me on HMR 500 (just liquids). I lasted 6 days lost no weight and was having an allergic reaction so I stopped.

What kind of allergic reaction do you have? To the shakes?

After drinking the shakes I was getting a tingling sensation in the back of my throat. My brother gets that feeling when if he eats brazil or hazelnuts (deathly allergic). I was'nt taking any chances. Again, also gave it enough time to lose some weight and I lost nothing. I was doing an hour of moderate cardio daily so based on the whole calories in/out business I should have lost a lot of weight. At that point I weighed more than 300 pounds.

What does HMR mean?

Its a brand of medical weight loss food system. Some people do liquid diet only 500 or 800 calories others get to have prepared foods like Nutrasystem.
