How weird that you're doing this now. I've been battling with weight for most of my life. Last June I stepped onto my scale and it read 330lbs. I'm 5'11". At once I started a sort of change in life style and within a few months I was down to 300. Then it got slow and it took the next three months to get to 290. Then I just hung out there until three weeks ago.
My issue is food control. So I decided to do something about it with Soylent. I spent an entire week doing test runs, taking notes on how my body reacted etc. My research is still far from conclusive. Here is some of what I've learned.
Don't mix it with anything. This was hard for the first week but then it became routine. In my case I decided to take extreme steps that shouldn't be taken, however my employment has next to no physical labor and I deemed it necessary. I decided on five snack sizes a day. That's 1250 calories a day; again dangerous. I take them at 8AM, 11AM, 2PM, 5PM, and 8PM. That's a three-hour block between each. I go to bed at 9PM and wake up at 7AM. The weekends are havens. I can do whatever I want, but I'll note that in a second.
I got a decent size piece of heavy Tupperware that could hold a bag of Soylent and the lid formed a tight seal. I left a half cup measuring cup inside the container.
Mixing was the first hurdle. It took forever to mix it in a coffee cup. Then I had what I consider a stroke of brilliance. Mason jars. On an unrelated note, I also discovered that I can scramble eggs for French Toast in a mason jar and it works perfectly. At first I was putting the powder into the jar, then the water but this made it a bit harder to shake the mixture. So I reversed the steps. It worked way better, but had a few issues. I had a hard time getting the powder into the jars. I got a mason jar funnel and that fixed the issue. Then I realized that I was only having three meals at work. So I decided to put the powder into three jars and take them to work instead of the Tupperware, funnel, and single jar. At some point I went back to powder then water since it was tedious carrying a one cup measuring cup and I kept forgetting it at work.
I discovered that I had to let the mixture sit for 10 minutes after mixing to remove burps and farts, completely by accident. During early trial runs, I would let the coffee cup sit to try and get rid of clumps. I never changed this and it only occurred to me later when my sister had gas trying to imitate me. I had her let it sit and low and behold, a missed research note was added to my notes. It also tastes better if you let it sit. Don't make it too far in advance as it gets sour in two hours. No idea why since there isn't any extra gas in the jar which would show signs of fermentation.
On the weekends I eat what I want. However, after the first week I can't seem to eat as much. I fill up faster. I also get annoyed at cooking. Doing a snack of Soylent only takes a few seconds and the jar rinses out creating no dishes. Still, I love eating. I realized early on that candy is a no-go after my sister brought in a box of Reese's Cups. That took the second week to recover from.
I figured out something I call result noise. It's fluctuations in the data cause by poop in the system. After two to three days, the noise is gone. Without the noise in the calculation I know I have base weight, or the lowest possible weight. I weigh myself in the mornings right after getting up and before I drink any water. A shirt, socks, and underwear only. I do this daily and record it on a spreadsheet with a graph.
In three weeks, I've gone from 292, to 274. The noise was about 6.5 lbs. So in reality, I've gone from 285.5 to 274, so 9.5 lbs in three weeks. I only do this Monday through Friday and I messed up one Monday, so fourteen days. That's not bad. It's sustained weight loss. I found that licking a block of salt kills my cravings during the week.
As stated, this is inconclusive. My target weight is 220lbs. However, I'm currently aiming for the 260 range at base. 1250 calories is just above starvation mode, so I have to be careful to not exert myself during the week. I can do my workouts on the weekends without issue.
These are the more important of my notes. I did mess up badly the first day. I took a Vitamin and had a minor overdose of Iron. Thankfully it didn't have any lasting effect beyond a minor silent migraine that night.
