This is how to lose weight. I watched a guy in my office lost 50+ lbs and kept it off. First, he bought one of those micro finger stickers to track blood sugar. Tone down carbs, and monitor when you go into kitosis. (Spelling?) This is when you body has exhausted the carbs you dumped in it, and now running off stored fat.
Once you have your carbs under control and are regularly going kitosis, you begin 12 to 18 hour fast. This can include your sleep time, so it's not that bad. Just a couple hours on either end of your sleep time.
Next, add some level of excercise to speed the process up.
This is the only diet I ve seen that really works. It doesn't work over night, but not that slow. It is the only diet I have seen that you don't hit "the wall" (insulin resistance) and stop losing.
Once you are where you need to be, watching carbs is easy. Go on vacation cheat away, then back to it on return.
It's been a year and he hadn't gained it back.
He goes to lunch with us probably 2 of the 5 work days, and brings his keto stuff on the others.
Once you have figured out when you go into ketosis you don't have to keep doing the blood test.
