Hello and welcome enigma42
What has worked for me is a combination of things. I have a photo of me when I was at a good weight and quite fit, which I have put on my laptop background screen - it acts as a reminder as to how I can look and is a great motivator. I want to be that healthy fit person again.
Next I made up a plan which involved listing the foods that I need in order to promote health and weight loss (Salads with small portions of cheese, chicken or tuna, wraps instead of bread, generally something like Egg or beans on toast or homemade muesli mix for breakfast, homemade mix of dried fruit, seeds and cashew nuts for snacks) I have one of the meal replacement shakes about every other day - usually for the evening meal. I always try to have some protein in each meal. I have celery and carrots available for snacks, but don't use them much. I have cut out the obvious baddies of icecream, margarine, sausages, chips, potato chips, lollies etc and cut back on bread, only having two slices of multigrain bread each day whereas before I got through a loaf in about 2-3 days, I've cut back on cheese (one of the loves of my life
) I was getting through nearly a kilo a week of cheddar, now I just have a couple of small slices with the salad. High density meats like beef I rarely have now, and when I do it is about half the size that I used to have. ... and I drink plenty of water.
I got some acai berry capsules at the same time I got the shakes from the chemist. I take two of them in the morning about the same time as I do my exercise.
Exercise: I have a fairly high tech, heavy duty exercise bike (probably similar to what they have in gyms) and started out at 10 minutes (which was about all I could do about 3 weeks ago) twice a day. I built up to 15min, 20min, 30min and I am nearly doing 40 min now.
In my plan I also set myself targets as milestones to my final destination, another good motivator. The targets are not set in stone and can be revised if they prove to be unrealistic or too conservative. In my case I never expected the weight loss to be quite so dramatic, having lost nearly 17kg in two months, and 11kg in November alone.
I had a medical before embarking on this journey to a mini-me, and found that heart, and blood pressure were up to it, and blood tests were good apart from an elevated blood sugar level (which I reckon was a binge on chocolate honeycomb a few days before)
And then I just did it. I joined this forum a few weeks later, and it has been very supportive and full of sensible advice.
So get a medical to make sure there is nothing in your blood chemistry which is responsible. Then make a plan. Get rid of the bad temptations that might be in the house, and replace them with healthy alternatives. Make exercise a habit.
So endeth the lesson
Now get to it!
