Week 1 review:
My maintenance calorie level should be between 1700 and 2100 according to different calculators.
Sat cal:2,400
Six days following : Average of 1425 per day (high of 1582, low of 1345)
Week average calorie per day: 1564
Result: Weight loss of 300g or .7lbs
This is not a lot of weight to lose but I only lost 1lb over the previous two months eating less than this. So this is working. I will change what I'm doing again because I don't think my metabolism has increased, or if it has it fell back again. I think this because over the last three days I was really cold. (I was reviewing students work in a hall and I was the only one who needed a coat). I do loads of exercise so I think to increase it a refeed more frequently or a block of refeed days may help. I'm following a low cal low GL diet, protein twice daily, with of one snack per day that's none of these.
The way my weight altered over the week was strange.Two days after my refeed day I weighed exactly the same, which I find really weird. I thought that my weight would go up soon after. On the Wednesday though my weight fell and remained at that lower weight each day after. So I seem to have used more calories on the Tuesday and the Wednesday and then maybe my body adjusted down again? So the leptin boost (if that's what's happening) lasted for three days after my refeed day.
Unfortunately I was too busy at work last week to shop for different foods to do a mid week refeed but I am determined to do this next week and see if this boosts weight loss further.
Next weeks plan: Sat and Wed refeed of 2200kcal, about half high carb foods
I will weigh myself every day this time to see if I can figure
out the pattern of weight loss/gain.
K9Owner, I had a similar problem on Saturday, I was still eating until 10 trying to get enough calories in me. It did not sit well in my stomach eating so late. I'm definitely aiming to eat earlier today.
According to body builders (who regularly get down to 0% body fat) high carb foods are exactly what you need on a refeed day, and they use past and pizza and sweet stuff to get their calories and their glucose levels high. So this may not be what you want to eat but it may be necessary. Protein is high in calories but won't give you loads of glucose and it's both that will cause the body to produce more leptin, according to some theories that I've read on leptin production, and body builders sites and forums, talking to a pro rugby player and one diet book.
One explanation that I read is that the body stores energy in three different ways. Glucose is stored in the liver as glycogen and blood short term, protein in muscle and fat everywhere. Glucose is the first thing that the body accesses, it's the easiest. When the glycogen stores are high then there is more leptin sent out as food is plentiful and our metabolism is raised, or returned to normal after a low cal period. If there's too much glycogen then it gets stored as fat after a time of course, but the body craves high calorie food on a diet because it wants to have this access to easy sources of energy to maintain a high metabolism. Short term doses of high cal food may be good for us. In theory. The day before a rugby match pro rugby players eat tons of high cal carbs, pasta especially, so that on match day they will be able to easily access far more energy than by eating any other food. These men run and wrestle almost constantly for eighty minutes every time they play and of course I don't but what they say and do ties in theories that I've read about leptin release. If the glucose stores are used up within a few days then this high cal food won't get stored as fat, and the metabolism is higher than previously so low cal eating will have a greater effect then.
I'm not sure when the body starts breaking down muscle instead of fat but I did read that there is a minimum amount of calories you can reduce before it does that. Muscle as I'm sure you know uses energy so if we're starving having less muscles means that we will live longer. So for this reason as well there must be a low limit for how little calories to eat and maintain fat loss. Do you know what that is? Right now I'm wondering if this new weight loss I had is due to higher leptin levels or is it because I'm not breaking down muscle to maintain a low metabolism because I'm above the minimum average calorie level for me.
I wish that I could find scientific studies to prove this stuff. At least body builders and rugby players seem to be a good source of information, and from long years of success keeping their fat low and energy high I believe what they say works for them but even then on their forums they have differing theories of when to refeed and how often. And I'm not lifting weights like crazy or playing rugby. I feel like doing a study myself on normal humans.

After the refeed day did you feel like you had more energy?
