Just finished sunday workout. Today it was stair climbing around 30 floors in total, all this while wearing my 25 pound weighted vest and carrying an extra 13 pounds on each arm, so about a total of 50 extra pounds, I finished with 50 pushups and some bicep curls. On Valentine's day I ran 10 kilometers, my time was 58.30 new personal record, I am new to running and I don't know if that's a good time but I weigh 247 pounds So, be gentle with me. Keep up the good work, thanks for your support and I'll see you on the other side.

I deliberately overlap DietBets in order to push me past the goals on one of them by having a larger goal on another: it keeps me ahead in the 6-month games like this one.

I'm now below my goal weight for Round 1 because another bet I'm in needs me to be below that already, so...it gets me ahead of the game.

I was close in that game this round, so yesterday I minimized my intake and drank a ton of water and a pot of green tea, and I made it. There will still be fluctuations, but I'm on a downward trend again, and I'm really really grateful for the encouragement and demands of these groups.

I will turn 49 on April 27. I'm at 268 now. My goal is to be 250 by my birthday. Totally achievable if I stay focused.

My weekly weigh in was approved this morning. I have met my month one goal. How is you weight loss going? Are you on a downward trend?

I’ve been very strict with my diet these past 3 weeks. But today was just difficult for some reason. Ate a little over my calorie restriction. Hoping it doesn’t show up on the scale.

My kid is in our h.s. musical, which is Spamalot this year as the property manager, my kid needed to find coconut shells, which were $10/ea on the internet. So we bought coconuts for $1/each at the market. Husband helped them use a hack-saw to slice them in half, kid pried out all the coconut meat, and I gave away most of the coconut to friends, then took a tray-full of shaved shards (used a mandolin to slice them) and toasted them.

DELIGHTFUL crunch, lovely flavor, and a light touch of sweetness. Nibbling on 1/4 to 1/2 c of the toasted slices...mmmmm.

Hey Team! Happy Friday!
I have two days left of my first 5 day water fast. It's harder than I thought it would be! You don't realize how much of your day is spent around food until you take it out! Lord, help me!
Also, if you want to see a really interesting docuseries full of more information on our nation's current health crisis than you can imagine, check out https://therealskinnyonfat.com/episodes/replay-weekend-guide.html.
This series is what got me back on track. It may only be available this weekend. Each video is over 2 hours long, but worth it!
