A Jay said:The heart rate naturally lowers with exercise thanks to improved metabolic efficiency, and I've also heard of people's heart rates being in the low 40s. But a check up is a good idea to make sure there's not something else going on.
What is also implicated in muscle cramps and spasms along with potassium is magnesium, sodium, and dehydration. So what might help with the cramping is drinking some Real Salt water before exercise with plenty of water during exercise.
As for the weight gain after upping the calories, that's pretty normal after coming off of a caloric restricted diet. The body adapts to the lower caloric consumption by down regulating a lot of different processes, and so once an excess is encountered the body wants to immediately shuttle it into the fat cells because it thinks it's in a famine and is trying to preserve itself. It can take up to a few weeks for the body to adapt to a higher caloric intake, and some of the initial weight gain can be just water as you suspected.
Hope this helps!
She does take 400 mg magnesium a day. Night is where she mostly has her cramps/almost cramps (like last night). I think they show up more as the nights start getting cooler. Hydration could be a problem. She doesn't like to drink a lot since she wakes up three or so times a night to use the bathroom and can use it once or twice during a health club visit too. We may try to make the off the diet period longer or add back in even more calories when off the diet.
