So, I been on a diet since the beginning of May (intermittent fasting - basically 4:3). Since that time, I've lost just under 10 pounds, which averages out to almost a pound a week. However the rate of weight loss has not been steady (I lost significant weight some weeks, and none others). Nor have I uniformly lost the weight off of my whole body (it has mostly come off my waist, when I was already hourglass shaped prior to beginning the diet). Why is this? (If relevant, I am a medium-sized woman in my late 20s.)
First: For weeks 1-2 and 6-8, I lost basically no weight. For the other weeks, I lost between 1 and 3 pounds each week. Why is this? Even accounting for the monthly weight spike during my period and ovulation (which don't seem to correlate with what I've been describing, anyway), this just seems odd, since I have been eating roughly the same diet for the past 10 weeks. For instance, I lost no weight for three weeks (weeks 6, 7, and 8), and then I lost three pounds the following week (week 9). What is going on here? Why is the rate of loss not even if my calorie consumption is roughly equivalent week by week? I don't think that this is water weight (as per this
helpful question recently), because I have already accounted for that (I typically lose 2 pounds on my fast day, which I assume is mostly water weight, as I have then have gained 1.5-2 of those pounds back after a day of normal eating)
Second: Also, the weight has not come off my entire body uniformly - it has largely come off of my waist, and to some extent my thighs and upper arms. My bust is the same size as previously, as far as I can tell (the cups of my bras still fit fine, although I have maybe tightened the band), and my hips seem to be pretty much the same size too. I was already fairly hourglassy before starting this diet (38" bust (34C or 36C) - 28" waist - 38.5" hips), and now I am more so (27" waist [or maybe 26.5"], with the other measurements the same). If I am hourglassy to begin with, why would my body not pull fat from my hips and breasts to even it out rather than pull from my waist? I'm not complaining (it actually helps me because I like to wear 50s dresses and don't wear jeans much, so I'm not super concerned by my big hips right now), but it just strikes me as a bit odd. If I were to do a different sort of diet (low-fat or low-carb), would this change the places from which I would lose weight? What controls where I lose weight from, and can I influence this? Also, the only exercise I have been doing has been walking. Would other exercise influence where I lose weight from?
