NOG 12. Weight Control and Slimming
Background
The rules in this section are designed to ensure that advertisements for weight control and slimming products and services receive the necessary high level of scrutiny.
Definitions
This section applies to advertisements for weight-control and slimming foodstuffs, aids (including exercise products that make weight-loss or slimming claims), clinics and other establishments, diets, medicines, treatments and the like. If applicable, they must comply with Section 11: Medicines, Medical Devices, Treatments and Health or Section 13: Food, Food Supplements and Associated Health or Nutrition Claims.
12.1 Radio Central Copy Clearance – Radio broadcasters must ensure advertisements subject to this Section are centrally cleared.
12.2 If they are necessary for the assessment of claims, broadcasters must, before the ad is broadcast, obtain generally accepted scientific evidence and independent expert advice.
| CLEARCAST GUIDANCE Clearcast expects to see substantiation, usually in the form of clinical studies, in support of claims for the efficacy of products that are claimed to aid weight loss. Such evidence should be comprehensive and robust and should prove of the claims made. Evidence supplied will be submitted to one of Clearcast’s experts for evaluation. If evidence does not stand up to scrutiny, claims may be rejected. Advertisers should use Clearcast’s Claim Support Model document when submitting scientific evidence. This can be found here. If products are licensed by the MHRA and claims do not go beyond those outlined in the products’ Summary of Product Characteristics, Clearcast will not need to seek independent expert advice. If products are registered as Traditional Herbal Medicines they should carry a statement to that effect e.g. “a herbal remedy traditionally used as an aid to slimming”. |
12.3 Advertisements for services offering remote personalised advice on health matters related to weight control or slimming are acceptable only if all staff providing that advice are suitably qualified and subject to regulation by a statutory or recognised medical or health professional body and the advice given is in accordance with its relevant professional code of conduct (see rule 11.9). That does not prevent advertisements that offer general information on health matters related to slimming or weight control.
| CLEARCAST GUIDANCE When considering advertisements for remote services, Clearcast requires sight of assurances that those providing advice are suitably qualified and registered with appropriate bodies. |
12.4 Advertisements must not encourage indiscriminate or excessive use of a weight-control or slimming product or service.
| CLEARCAST GUIDANCE Advertisements should do no more than encourage people to reach their ideal weight and should not suggest that regular dieting is healthy or desirable. |
12.5 Advertisements for slimming or weight control products or services must not be addressed to people under 18, use creative treatments likely to be of particular appeal to them, or feature any person whose example people under 18 are likely to follow or who has a particular appeal to them. This rule does not apply to advertisements for calorie-reduced or energy-reduced foods and drinks, provided the product is not presented as part of a slimming regime and the ad does not use the theme of slimming or weight control.
| CLEARCAST GUIDANCE Unless they are playing an incidental role, no one under the age of 18 should feature in advertisements for slimming products. Clearcast assigns a restriction to all slimming advertisements to ensure they are scheduled away from programmes that are directed at or likely to appeal particularly to those under 18. See rule 32.2.4 of the BCAP Code. |
12.6 Broadcasters must obtain suitably qualified independent medical advice or other suitably qualified health specialist advice on the safety and efficacy of weight control and slimming products or services before broadcast. In particular, the advice must satisfy broadcasters that:
- 12.6.1 the slimming product or service is likely to be effective and will not lead to harm
- 12.6.2 clinics and other establishments offering medically supervised treatments are run in accordance with the National Minimum Standards Regulations issued by the Department of Health or, if they operate abroad, broadly equivalent requirements.
| CLEARCAST GUIDANCE Clearcast expects to see full details of diets and eating plans. These will be submitted to one of Clearcast’s experts for evaluation and confirmation that they are safe to follow and nutritionally sound. If Clearcast or its consultants are not satisfied with information provided, advertisements may be rejected. The ASA has ruled on this issue. The ruling can be found here. |
12.7 Promises or predictions of specific weight loss are not acceptable for any slimming product.
12.8 Health claims in food product advertisements that refer to a rate or amount of weight loss are not permitted.
12.9 Claims that refer to specific amounts of weight that have been lost by an individual must state the period over which that loss was achieved and should not be based on unrepresentative experiences of the slimming or weight-control product or service (see rule 12.8). The amount of weight lost and the period over which it was lost must be compatible with generally accepted good medical and dietary practice. For those who are normally overweight, a rate of weight loss greater than 2lbs (just under 1kg) a week is unlikely to be compatible with good medical and nutritional practice. For those who are obese, a rate of weight loss greater than 2lbs a week in the early stages of dieting could be compatible with good medical and nutritional practice.
| CLEARCAST GUIDANCE Clearcast considers claims such as “drop a dress size” or references to inch loss as references to specific weight loss and asks that they are also accompanied by a statement of the time in which the drop or loss was achieved. e.g. drop a dress size in six weeks”. |
12.10 Low-calorie foods and drinks, if advertised as, or as part of, a slimming regime or if advertised using a slimming or weight-control theme, must make clear in the ad that the product merely helps weight loss as part of a calorie-controlled or energy-controlled diet.
12.11 Except where stated in 12.11.1 and 12.11.2, advertisements for weight control or slimming products or services must not be targeted directly at individuals with a Body Mass Index of 30 or above (obesity) or use testimonials or case histories referring to subjects who were or seemed to be obese before using the advertised product.
| CLEARCAST GUIDANCE Clearcast will seek specific written assurances that those featured in advertisements have a BMI between 25 and 29.9. If there is any doubt about precise BMIs Clearcast may seek signed testimonials from individuals. |
- 12.11.1 Advertisements for clinics or other establishments that offer treatment under suitably
- 12.11.2 Lifestyle weight management programmes which meet the following standards may make responsible references to obesity in their advertisements. These programmes must:
- be shown to be effective at 12 months or beyond
- last at least three months
- be multi-component; addressing dietary intake, physical activity levels and behaviour change
- be developed by a multi-disciplinary team; including input from a registered dietitian, registered practitioner psychologist and a qualified physical activity instructor, and
- be provided by staff who are trained to deliver the programme in question.
| CLEARCAST GUIDANCE NICE guidance can be found here. |
12.12 Advertisements for weight-control or slimming products must not suggest or imply that to be underweight is acceptable or desirable. If they are used, testimonials or case histories must not refer to subjects who are or seem to be underweight. Underweight, for the purpose of this rule, means a Body Mass Index below 20.
| CLEARCAST GUIDANCE Clearcast will seek specific written assurances that those featured in advertisements have a BMI of 20 or above. If there is any doubt about precise BMIs, Clearcast may seek signed testimonials from individuals. |
12.13 Advertisements for specially formulated products intended for use in energy-restricted diets that, when used as instructed by the manufacturer, replace the whole of the total daily diet or one or more meals of the daily diet must comply with the Foods Intended for Use in Energy Restricted Diets For Weight Reduction Regulations 1997 (as amended), specifically:
- 12.13.1 advertisements for such foods may not be offered under any name except “total diet replacement for weight control” or “meal replacement for weight control”
- 12.13.2 advertisements for such foods may not refer to the rate or amount of weight loss that could result from use of the product.
12.14 For the purposes of this rule, very low-calorie diets (VLCDs) are those with a daily intake of less than 800 kilo-calories. They must comply with the provisions of the Food Safety Act 1990 and relevant regulations made under it, including those on advertising. These conditions apply to advertisements for such products:
- 12.14.1 the ad must include a clear injunction to consult your doctor before embarking on the diet
- 12.14.2 the diet must be positioned as a short-term measure only
- 12.14.3 testimonials or specific case histories must not be used
- 12.14.4 independent medical advice must be sought on whether the proposed ad accords with the guidance on “Obesity: the prevention, identification, assessment and
| CLEARCAST GUIDANCE Clearcast will require sight of the independent advice sought. The advice needs to be provided by a suitably qualified medical professional. |
12.15 Advertisements for establishments offering weight-control or slimming treatments are acceptable only if they make clear that dietary control is necessary to achieve weight loss. An exception is made for clinics and other establishments that provide immediate weight loss surgery under suitably qualified medical supervision and are run in accordance with rule 11.9. Those clinics and establishments must not refer to the amount of weight that can be lost.
