Advice for newbie with tired muscles?

I'm 37, 5' 10" and 186lbs. About 5 weeks ago, I was about 205lbs and
wanted to get into some kind of shape after doing nothing about it my
whole life. I changed my diet significantly and started on the
treadmill and using weights (all done at home). I do about 45 mins.
on the treadmill one day, then the next lift weights (not trying to
get huge or incredibly cut so I just do all major muscle groups in
about an hour) and repeat with no days off if I can help it. Lately
though, my arms have just been feeling very tired all the time...even
just brushing my teeth or toweling off after a shower I can just feel
my muscles almost burning. Is this normal?? Do I need more rest days
or do you think it's a nutrition thing? Below is an average day of
what I eat...(I seem to have a high metabolism and get hungry alot
during the day which is the reason for the bars)....only liquid is
drinking water all day. Any advice would be appreciated (and even if
it has nothing to do with my problem...please feel free to criticize
my eating habits...I'll take any help I can get).

Breakfast 8am:
Light Yogurt
Bowl of cut up melon/canteloupe

Snack 10am:
Zone Perfect bar

Lunch 12pm:
1 PB&J (Whole grain bread with natural peanut butter and a little
jelly)
1 banana

Snack 3pm (not always...sometimes just wait until dinner):
Zone Perfect Bar

Dinner 6pm:
Grilled chicken on Wheat roll with lettuce and tomato w/honey mustard

Snack 8pm:
Either Zone bar or an apple with a light yogurt

That's a lot of weight loss for 5 weeks. Calorie intake looks too low
for the amount of exercise you say you are doing. have some eggwhites
in the morning and shitcan the banana and jelly for lunch, too much
sugar, maybe a nice garden salad with some protein... try adding the
usual supplements and for the pain in your joints get some MSM.
