Popular types of Lose Weight products
Tablets and sachets are often chosen by people who prefer to keep their usual meals and use a product around mealtimes, following label directions. Meal replacements (ready-to-drink shakes, powders and bars) can suit shoppers who want a more structured approach to portion planning—particularly on busy days—while keeping at least one balanced meal as part of a wider routine where directed. On this page you’ll see popular formats from XLS and Slim Fast to help you compare like-for-like.
How to choose the right option
- Pick your approach: meal replacements are for planned portion control; tablets and sachets are used alongside meals as directed on the label.
- Choose a format you can follow consistently: ready-to-drink for convenience, powders for at-home routines, bars for portability, tablets/sachets for simple mealtime use.
- Check suitability before you buy: review age guidance, allergies/intolerances and warnings—especially if you have diabetes, digestive conditions, or take regular medicines.
- Avoid doubling up: don’t combine similar products unless a pharmacist or GP advises it.
- Start with a sensible pack size: try a smaller pack if you’re new to a format, then scale up once it fits your routine.
