Hi there, KATX . . .

. . . glad to meet you.
Sometimes, we actually eat more than we think we do -- or, at least, make some poor food choices that do nothing to nourish our bodies and give us the strength to lose weight. It is also very possible to eat too little and this can force your body to try to hang onto every little calorie it can get.
Not saying this is what is happening with your case . . . but how about giving us a sample of your daily eating and maybe we can help you tweak things into action a little better.
Look forward to hearing more from you soon . . .

. . . and congratulations on the loss so far.
