When your body fluctuates from day to day, you are not actually losing or gaining weight (fat/body mass). Those fluctuations are due to how much water you are restraining, what part of your cycle you are in, etc. You will not get accurate results if you weigh yourself every day. You should pick one day a week, and weigh yourself at the same time on that day. Also, if you reduce your calories but don't do exercise, specifically strength training, some of the weight you lose will be from muscle-- not just fat (usually 60-70% fat, 30-40% muscle/lean mass). Doing more exercise will also help your skin tighten up once you lose weight. I recommend the fooducate app. If you pay $5 for the upgraded version, it will track all of your nutrients (% carbs, % protein, % fat) as well as your grams of sugar, saturated fat, net carbs, salt, etc. It's extremely helpful in figuring out what you are getting too much of and too little of. It's super easy and, if you stick with it, you will absolutely see results. I don't have any weight to lose anymore, but I still use it to help me stay on track. What I discovered using the app is also that a lot of seemingly healthy foods that you buy in the grocery store have ingredients that are actually really bad for you-- if you scan those in fooducate, it will point that out and offer an explanation. For instance, the 98% lean turkey I was buying had a bunch of unhealthy stuff in it-- so now I buy a different brand without that stuff.
