Everyone is different as to what agrees with them at 7 weeks. For me it was always beef. Chicken thighs over breasts- as they are moister. No tuna salad until after 6 months but I could do chicken salad... Still almost 2 years out cold cuts aren't my friend. I couldn't microwave anything- too rubbery.

Make sure it is moist, chew well, small bites....add a little broth, sauce, or condiment if needed.

I was going to try the 5 day meat test simply because I'm 7 weeks out and have only lost 18 lbs but nothing lately ... What kind of meats are best ? 

My surgery was on June 11th and I enjoy having that one cup too!  Thanks for asking this question.  My doctor said he prefer me to have ice coffee for a while and possibly decaf due to dehydration.  I'm ok with decaf, I just like the warm mug in my hand. ?

Honestly, I'd just eat LCHF and write down literally everything.  If you're eating under 1200 calories and not losing weight, you're either overeating, or eating too many carbs and not tracking them.  Carry a notebook with you and immediately write down each bite as you eat it.  I discovered pre-op I was eating far too much.  I was shocked at what I was eating!

Also, 1/3 cup of nuts has 273 calories.  A cup of veggies has like 50.  It's also much easier to overeat nuts than veggies.  You'd be better off eating 3 ounces of beef instead for slightly fewer calories and 2x the protein (or more).

I ate 1/2 a waffle house waffle with sugar free syrup and a few bites of hash browns with my eggs before my pre op liquids.

I think I also ate a donut also.

Other than that- I was good because I had been dieting for 6 months prior due to insurance req- and had already lost 50 pounds before surg
