...information for health professionals

Pregnancy Royal College of Midwives Logo

We worked in collaboration with the Royal College of Midwives (RCM) to develop our policy on the best way to support our members in managing their weight during pregnancy. The RCM were pleased that Slimming World were able to offer this support – and, importantly, to help women avoid excess weight gain, which could result in an increased chance of problems during pregnancy and birth.

If you’re not a health professional, and you’re interested in joining Slimming World while pregnant, your local Consultant can give you more information.

Our policy for pregnant members

Slimming World do not advise on weight change during a member’s pregnancy and do not encourage weight loss during this time. Instead, we support members in eating a healthy diet and remaining physically active. We also support members in achieving any weight change recommendations made by their healthcare team, particularly in preventing excess weight gain during this time.

Therefore, as part of our policy:

  • Any member wishing to continue to attend their Slimming World group during their pregnancy is required to gain the support of their midwife.
  • Slimming World do not advise members on their weight change during pregnancy.
  • Slimming World group Consultants support the member in maintaining a healthy balanced diet to manage their weight safely, as advised by their midwife.

Collaboration with the midwife

  • We have a Pregnancy Weight Management Form for our members to take to their midwife at each appointment.
  • This can be used by the midwife to make any necessary recommendations or suggestions regarding their weight control.
  • If the member does not require their weight to be monitored during their pregnancy, this can be indicated on the form.
  • With the midwife’s support, the member can then continue attending their group to receive the encouragement and regular support in continuing to eat a healthy, balanced diet and remaining active during their pregnancy.

If we notice that a member is losing weight during pregnancy, we will monitor their weight and food intake carefully, following the procedure outlined here:

  • If a pregnant member reaches a cumulative weight loss of 5lbs during pregnancy – and she hasn’t been recommended to lose weight by her midwife – we will ask her to fill in a food diary during the following week in order to check that she is eating a plentiful and varied diet, and is not being too restrictive.
  • If a pregnant member loses 4lbs or more in any one week during her pregnancy, again we will ask her to fill in a food diary.
  • If a pregnant member continues to lose weight and reaches a cumulative weight loss of 7lbs – and hasn’t been recommended to lose weight by her midwife – we will ask her to consult her midwife, taking her food diary with her to show she is following a healthy balanced diet.

Slimming World recommends breastfeeding mums consume a healthy, varied diet to supply all the extra nutrients needed and advise that they make healthy food choices rather than increasing their intake of high-fat or high-sugar foods.

A booklet detailing the current recommendations for healthy eating and food safety during pregnancy and breastfeeding is available to members in group.

Slimming World's approach supports members to make lifestyle changes for the future of both themselves and their family. It’s not about a quick fix or fad, diet but a healthy, balanced diet to enhance good health. Through their programme they also encourage people to begin to build activity into their daily lives
