Weight does not equal fat...
At your height and weight, all that riding will have made you stronger; your muscles are likely to be firmer and stronger adding weight.
I have not lost one kg in the last five months, but I am leaner, skinnier, stronger and fitter than I have been in years. My legs are solid now.
When I take measurements I can see that the fat is going down and that the muscles are firming up.
I am doing the same as you; reveling in the fitness and loving the time I get on the bike. It is like meditation for me, and I am getting fitter as I go.
Sure, I would love to have lost another 10kg over the last half year, but what I have gained in fitness, strength and metal health is so much more important to me...
I also know that if I threw in some salad/tuna lunches, more fruit instead of bakery items, and a little gym work, I would probably knock those 10kg off pretty quick. But, for me, the weight loss journey is more of a lifestyle choice. I choose to ride because I love it, and it will help me lose the weight over time without having to be specific about my eating.
Oh, and don't worry about the Lycra... Many of us are the same. You are who you are and just being out on a bike enjoying life makes you sexy!!!
Keep on rolling Fiona!!!
