The wife rates the Davina one too
I think it has its good points, but I'm not focusing on the exercising
Even if you have a short routine of stretching, jogging on the spot, press ups and situps you can raise the heart rate. Try a routine which lasts at least 20 minutes.
Also take a look at the sticky as this explains how to work out your daily calories required. If you get stuck, shout.
YOu may want to try having high and low carb days to help keep you burning fat without your metabolism slowing. Just reduce the carbs in the meals and increase the protein. 1 gram of carbs is the same as 1 gram of protein calorie wise so the two can be interchanged at meal times.
Just to remind peeps
1 gram of protein = 4 kcals
1 gram of carbs = 4 kcals
1 gram of fat = 9kcals!
Also watch out for simple sugars (most sweet stuff) and look at the labels on low fat stuff as this will probably have a fair bit of sugar too. SO stick to good wholesome food - lean meats, comples carbs(brown rice) and fresh veggies
Good luck
