Hi!
I am wondering if you potentially aren't eating ENOUGH. I know that sounds counterproductive, but if you are only consuming 1370 kcals (or around that number) per day your body may be in starvation mode. I am a Biologist with emphasis in Anatomy and Physiology and it might be that your body requires more fuel so that it doesn't hold on to fat and burn your lean body mass. Have you had your body fat tested? If you have been consistently working out burning on average 800 kcal let's say 5 days a week and eating only 1370, and your bmr is somewhere around 1500 kcal (I don't know how old you are but that is with an age of 25 and height and weight added in) then you would be putting yourself at a daily deficit of 930 kcal per day, 5 days a week which is cutting out enough calories to lost about 1.5 a week for 7 months should be 42 pounds! When you first began this process your body was "shocked" by the change in your eating and exercising habits and began to shed the fat. However, sustained time periods of severe calorie deficit in the form of not enough fuel being put INTO your body (not the same as burning it through exercise) can cause your body to worry that it won't be getting the proper amount of calories and it begins to actually store fat, and use your lean body mass (see that as muscle) for fuel. The hard thing about that is that protein is actually less calories per gram when used (4 as opposed to 9 for fat) and this causes your metabolism to SLOW DOWN. Unfortunately many people believe that eating less food and exercising excessively will help them to lose weight faster, when in reality staying close to your BMR of 1500 (maybe only cutting out 100 calories of food) and exercising to BURN calories is a better way to lose weight consistently. This way your body isn't going to "hold on" to the fuel it desperately needs, your metabolism stays boosted (eating 5-6 small meals for those 1400-1500 kcals helps a lot too!), and you continue to consistently lose weight without the plateaus that extreme caloric deficit can cause. I hope that helps, perhaps sticking to a strong 1500 kcal diet and burning those 800-1000 kcals a day would be a good boost for your body for a few weeks and you would probably see a loss in that time (not huge but should be about 1-1.5 lbs per week with your BMR calculation). Also adding in strength training of any kind (lean muscle burns calories when you aren't doing anything!) is a great way to boost your BMR so that you can stay within a reasonable calorie consumption number without starving your body. I know that was really long but I hope that it helps! Keep trying and stay positive!
