I have been on atkins for about a month and a half and have lost 10 pounds initially (in about 3 weeks) but have not budged for 2 weeks even though I am continuing with a basic induction type of diet. Also I feel week all the time and this has an effect on the amount and quality of my workouts. Finally except for a few times in the first couple of weeks my urine never tests positive for ketones.

hey,
there is something your eating that could be causing you to stall and knocked you out of ketosis. if your never testing positive you are most likely not burning fat. it could also be your water intake if it is a lot, but you should atleast have a lightest pink at some time or another.

try backing off the food you are having that you think might be hindering you. you can post what you eat here and im sure we can help you.

i test every morning and mine is always dark purple, but as i drink my water through the day it is light pink to negative. even if it is the lightest pink you are in ketosis.

it is normal to feel weak. your body has to adjust to burning fat for fuel instead of carbs. you should be taking a multivitamin and some type of fish oil a day.

hope this helps.
