Aw but you don't look like a girl!!
Dude,....the protein intake is huge.
If you aren't getting it, your body cannabilizes your muscle tissue for what it needs,...resulting in weight loss but not a long-term beneficial way to go. Your body cannot convert protein to fat or stored energy. it either uses it or passes it through,..if you are drink your 60+oz of water a day,...otherwise you set yourself up for kidney stones.
I found the 60 gms a day presribed by the WLS diet is an absolute minimum for guys. Most health and sports magazine and internet articles will prescribe 1 gm of protein for every pound of desired weight,...that would be more like 180-200gms a day (how you doin??). Plus some exercise to keep the body realizing it wants that muscle tissue for work and not lunch.
I hit an energry wall when I started walking 4+ miles a day. I learned about increasing my B12, for energy, (I take a sublingual 2500 mcg tablet and a 1000 mcg liquid B Complex every morning plus another 1000 mcg of B12 in the afternoon). I now take a (pre-natal) multivitamin with 28 mg of iron twice in the morning and if it is a heavy strenous day (manual labor or workout), I;ll take two more in the late afternoon. The iron improves the oxygen carrying ability of the blood to the muscle tissue for metabolizing energy. And lastly, I take a potassium supplement and try to eat 1 or 2 bananas a day as it helps to build muscle tissue and it keeps me from feeling weak-kneed during the day. I also take a potassium pill or eat a banana after going for a 6 mile jog/walk (its a part of the good stuff in Gatorade without the sugar and carbs of Gatorade).
You are experiencing a standard aspect of Post-op recovery. How you deal with it has long term health impacts. Step 1 is to get your vitamins and supplements balanced as work best for you and step 2 is to keep pushing the envelope and you will have great results as the body responds. I started walking 5-10 minutes a time once to 3 times a day and that took effort to get out there but they promised it would make me feel better. I can now go 6 miles in 1 hr 20 minutes (slow athleitc wise but vast improvement for me). I'm down from a 60 pants to a 40 and down 176 lbs form 408 to 232 and losing. I have never felt better and been happier about my health. I am just getting cranked on regular upper body weightlifing and trying to increase my jogging to jog an entire 10K without having to walk. It is an amazing transofrmation way beyond the results I had hoped for after surgery but I am loving it. I tell you this not to brag but to enusre yo that you can do at least this good and probably better yourself as you stay with the program and get some exercise in areas that you enjoy.
Just hang in there so you don't become a punie flabby girlie-boy!!!
