In April, the nurse at our GP surgery took my BP and it was 138/94 and my HR was 79. She was concerned and I don't remember it being that high before. Shortly afterwards, my partner bought an Omron inflating-cuff monitoring machine for his own use - so I had a go.
On 11th May my BP was 141/91 and resting HR 74 bpm. OK, but not good.
Today, after Week 7, it's 119/80 and resting HR 59 bpm which is well into the 'healthy' range again.
Both times I took the reading was best of 3 measurements and all 3 were at this time of day.
So if you're disappointed with the amount of weight loss, think beyond the scale. The benefits to your cardiovascular health are hidden, but perhaps more important than your weight.
