your period should in no way affect your OVERALL weightloss efforts.... Yes, you might experience a stall during whatever phase of your cycle causes you to bloat up like a water balloon (for some its during ovulation, for some during teir period itself, for others, the week before). This has NO EFFECT WHATSOEVER on your FAT LOSS... it merely MASKS the fat loss during that period (pardon the pun)
Fat loss will/can still continue within your body even if the opposite isshowing up on the scale for a few days, as long as you continue to be in a caloric deficit.
HOWEVER, keep in mind that FAT LOSS CAN AFFECT YOUR PERIOD.
Women whoa re hormonally more sensitive, or doing a more aggressive deficit--esspecially when coupled with aggressive exercising-- can lose their periods. Some feel its a blessing, but a woman's menstrual cycle is a vital sign of sorts. If it starts acting wonky its a sign that your body is TOO STRESSED. So keep a watchful eye and take note if your cycle starts to change in any way...... lighter, more frequent, less frequent, etc.
I lost my period for over 2 years. Every doctor i saw (OB/GYN, GP, Endocrinologist) they all wrote me off and told me i had forced my body into menopause (at 30!!) and would never have children again......
i know thats not what you asked about, but i saw an opportunity to bring up an important issue
