I'm no fan of short intensive programs. They may be too much for you to sustain, and in any case, even if they work if you consider them 'done' and revert to bad habits once you are done they haven't really accomplished much.

Better to find a balance where you can bear to sustain it 'forever' with modest allowances for misbehaviour, and to keep at useful and sustainable things (e.g build a garden wall, use a mechanical pusher mower, replace shopping by car with bikes or a rucksack - or replace commuting to work by walking or cycling (if you *must* drive or use public transport because of distance/terrain, then parking some reasonable distance away and walking a significant part of it is still better than door to door). If you get in your 'minimum' recommended activity in your daily movement to and fro, then failure to be consistent with additional 'fitness' training is far less damaging than if you structure things so you *have* to do the 45 minutes on the exercise bike or lifting weights. You can still try to do both, but have the flexibility to modify activity and diet to suit what you actually find yourself doing.
