I’m taking a course called “Fitness and prescription” [Conditionnement physique], which is (naturally) all about prescribing fitness interventions. Fair enough. We’ve just finished a unit on body composition, in which a short section at the end delineated “guidelines” to follow on how to address weight gain:
– Eat often; eat larger portions; snack; drink milk and juice with meals (fair enough)
– Eat high-calorie foods, but stick to low-fat options (uhhh)
– Above all, do not gain too much fat. Aim only to gain lean body mass (wait, what?)
The prof went on to explain that while weight gain is necessary, fat gain shouldn’t be the goal. At this, I raised my hand. “What about women with amenorrhea? They’d definitely benefit from gaining some body fat.” Cue blathering about “critical fat mass” and women below 13% body fat and yes, amenorrheic women might benefit from gaining some fat, because sometimes women who drop too low in body fat percentage skip their menstrual cycle for a few months.
Well. As someone who skipped 30 months of her menstrual cycle, fat gain was definitely in my interest. So I gained weight. On larger, more frequent meals, full-fat dairy products, additional carbohydrates. Lots of vegetables and fruit throughout. This was by no means unhealthy. I am now the proprietor of a body with more lean mass, and (yes) more body fat. I had to go above and beyond my previous “high” weight to restore my menstrual function, and I’m maintaining here without exactly trying. I exercise regularly. I eat when I’m hungry and as my schedule allows. I eat a lot of vegetables. I don’t usually get enough sunlight or enough sleep.
I’m not entirely comfortable at this weight, but this is where my body wants to be right now. This is where I can drop and do sprint workouts whenever, make the half hour trip to school in the morning and back again in the afternoon (weather permitting). This is where I can lift heavy (for me) weights, or skate or ski, or attend random classes, or train for a 10k race. I can spontaneously go to yoga (as is the plan tonight) with a friend and stretch beyond what I believe I can do.
I have health-related goals, like working out more regularly or attending yoga classes at least once a week because they relax me or going to bed earlier to ensure I sleep enough or walking in the sunlight to maximize my vitamin D even in these frigid winter months, but weight loss or anything related to food-restriction can’t be a part of those.
Just a friendly reminder that body fat is an endocrine organ. Hunger/satiety hormones such as leptin, grehlin, and neuropeptide y are directly related to body fat levels; these communicate with the hypothalamus. The hypothalamus then uses this hormonal information to regulate a huge number of physiological processes, such as appetite and temperature and yes, fertility (generally via pro-hormones). This is a gross over-simplification, but all that to say that we actually do need body fat, and sometimes fat gain can be the primary goal. This culture of fat-fearing needs to stop.
Women need enough body fat to be fertile. End of story. While I have no intention of having children any time soon, I value the proper functioning of my body and see my menstrual cycle as a sign that I’m on the right track, health-wise. Enough body fat also regulates appetite, and I’m not chronically hungry any more (meaning I can think of things beyond my next meal). These are well worth the “extra” (required) weight.
