It can be a challenge to prevent weight from creeping up over time in the current culture and with busy, demanding lives where time for you can be hard to prioritize.
The most sensible goal for your actual weight is usually for it to be generally stable over time and to resist trying to keep it somewhere under this that is unrealistic and unsustainable.
The problem with focusing on weight loss, apart from the fact it doesn’t work after the first few weeks, is that you totally miss that actually you are doing well just being healthy and stable. It can also prevent you from appreciating other things that may be changing and are more meaningful, like blood pressure, sleep or mood.
Shape change is inevitable and normal throughout life, but particularly noticeable at times like pregnancy, menopause and older age for women. Studies have shown for a long time that being about 10% overweight is associated with better health and living longer (even though I never recommend comparing yourself to population based measures like BMI).
So occasionally check in with yourself, look at the big picture about your health and lifestyle and reorganize your lifestyle if you need to. Heath at all ages, shapes and weights comes first and deserves all your appreciation and respect – and some time.
