10kg goal, what to expect week by week during your first month
In the first month of a 10kg goal, expect a fast start, a slower patch around week 3 and, by week 4, habits that begin to feel normal. 10kg is about 1 stone 8lb. Knowing in advance how the early weeks tend to unfold stops you from giving up just when things are starting to work.
A coach from the club reviews your circumstances alongside you and suggests the right next steps.

Week 1, the number that flatters
The first few days often bring a big drop on the scales. Part of it is water, because your body holds less fluid when you eat fewer salty and starchy processed foods. Enjoy it, but do not expect every week to look the same. Some people also feel a little tired or irritable in these first days as their routine changes. That usually passes quickly once meals become regular.
Use this week to set the basics. Eat 3 regular meals, base them on the proportions of the government Eatwell Guide, and notice when and why you snack.
Week 2, finding your rhythm
The novelty fades and real life returns. A birthday, a late meeting, a tired evening. This is where a plan for awkward moments helps. Keep 2 or 3 quick, balanced meals you can make in 15 minutes, and our list of snack ideas for when hunger strikes between meals.
Week 3, the slow patch
Many people see little change around now. The water effect is over, and fat loss shows up more slowly. The NHS advice on overweight and obesity suggests aiming for 0.5 to 1kg a week, so a slower week is normal, not a failure. Look at other signs. Is your belt on a new notch? Are you less hungry at 4pm?
Week 4, habits that hold
By the end of the month, the morning routine and the regular meals should feel less like effort. This is the moment to add 1 thing, rather than 10. A daily walk, for example, or a vegetable at every lunch. For a sense of how to keep going, read our page on keeping weight off for good.
Weigh in the right way
- Same day, same time. Once a week, in the morning, before breakfast.
- Write it down. A line on your phone is enough, so you see the trend rather than a single number.
- Look at the month, not the day. A month of steady effort tells the truth better than any single morning.
A morning start in Bicester
At Bicester Nutrition, the first assessment is free, and it is where a coach trained in nutrition helps you set your first targets. Members then have breakfast at the club each morning before work, which keeps those early weeks on track. If you live in Elmsbrook or Kingsmere, it fits easily into the drive or walk to work.

Your weight loss curve
Add your profile and the curve is redrawn at once.
Losing 8 kg at the median pace would take roughly 11 weeks, or around 4 months at the gentlest one.
Most guidance puts lasting weight loss at 500 g to 1 kg per week, which is the ideal zone on the chart. Lose more than 1 kg per week consistently and the body eats into muscle and not just fat, shown by the hatched zone.
This projection is a rough guide only. Each person’s journey is their own, and results are not the same for everyone. The sums are done on your device, with nothing stored or sent anywhere. Over 65, speak to your doctor before anything else.
How this curve is calculated
At the top, the zone’s edge marks 500 g per week, the gentlest rate. At the bottom, its edge marks 1 kg per week, the point where risk starts.
Weight comes off faster in the first weeks, much of it water, before the pace eases. Beyond 40, the median curve gradually flattens as metabolism slows down. With the same effort, men generally lose a little faster than women.
Like real life, the journey curve includes plateaus a few days long and minor regains. It is no prediction of the path you will follow.
