Any keto insight? I lost 9lbs in the first week, and now 2 in 2 weeks.

Went to the gym and showered in time to still get to church even with a late start.

Question- if I win round 1 and don’t lose enough round 2 but lose my 10% by round 6. Do I still win $? I think I just won’t win round if I use the above scenario... someone help! :) this is my first 6 mo diet bet so I’m a little confused. Thanks all!

Feeling a bit lost. I am eating healthier but im struggling with activity. Im starting a new position at my company and it scares me. I am stressed trying to learn it and when im stressed i want to eat. So far i have resisted but its hard.

Had ribs today. Just normal amount. Weigh in went fine. Still below to win first round. Tomorrow eat normal. Then back to daniel fast on Monday for 5 days. I believe I can get the next round goals by Sunday.

My husband was wiping our son down after he had a cupcake and handed me the rest of the cupcake to throw away. I just stood there looking at him until he realize what he'd done. Let's just hand an alcoholic an open bottle of rum, shall we? I did throw it away, but today, it was a real struggle.

I’m so so so so so proud of all of you who are hitting your round 1 goals already!

It’s also so heartbreaking for those of us who aren’t. Those of us who aren’t even close. Sigh. I’m not giving up. I’m not quitting. I’m hanging in. And I’m pushing. There’s still time!

So I bit the bullet and joined a gym - I realized I just need the guidance and accountability factor because I'm not getting it done at home. I refuse to let all of my fitness progress over the last year reverse just because I couldn't kick myself in the rear and stick to a routine! So off to gym classes. Perhaps I'll make a few friends :)
