2 weeks ago, I started cutting out an evening meal, drinking only a fruit/vegetable shake. I only eat weetabix and mango for breakfast and 2 sandwiches(4 slices of loaf) for lunch. The only other thing I eat is mixed nuts in the evening when very hungry.
I was 89 kg and dropped to 87 kg, but now 88 kg. I am 190 cm tall.
I also run 25 km per week.
What could I be doing wrong?
