What is weight loss support?

This is the broader category around fat burners: meal replacement shakes, high protein low kilojoule powders, fibre and appetite products such as glucomannan and psyllium, apple cider vinegar preparations, and chromium. The common thread is helping you hold a deficit rather than claiming to create one.

Fat loss comes from eating fewer kilojoules than you use, sustained over weeks. Nothing in this category replaces that, and any product promising results without it is overselling. Judged on that basis, the most useful things here are the least exciting ones. Protein and fibre both help with fullness, and a meal replacement removes decisions on days when your eating tends to fall apart. Those are real advantages, and they are advantages of structure and satiety rather than metabolism.

How it is usually used

Meal replacements are generally used for one meal a day, most often the one you are most likely to skip or get wrong. Fibre products need plenty of water and are taken before a meal. Protein is best spread across the day rather than taken all at once. Supplements are not a substitute for medical advice. If you are pregnant or breastfeeding, take prescription medication, or are managing a health condition, check with your doctor or pharmacist before starting something new.

Frequently asked questions

Do meal replacement shakes work for weight loss?

They can, mainly because they make portion control automatic and remove a decision on a busy day. The research generally supports them as a tool when used for one or two meals rather than as a whole diet. They work while you use them, so the part that matters is what you do when you stop.

What is the difference between a meal replacement and a protein shake?

A protein shake is mostly protein. A meal replacement is built to stand in for a meal, so it includes carbohydrate, fat, fibre and a vitamin and mineral profile as well. Using a plain protein powder to replace meals regularly will leave gaps in your intake.

Does apple cider vinegar help with weight loss?

The evidence is thin and the studies are small. Some suggest a very modest effect on appetite or blood sugar response, but nothing that would meaningfully change body composition on its own. It is popular well beyond what the research supports.

How does fibre help with appetite?

Soluble fibre absorbs water and forms a gel, which slows stomach emptying and increases fullness. That makes a deficit easier to stick to. Fibre products need to be taken with plenty of water, and increased gradually, or they cause bloating and discomfort.

Is protein useful when trying to lose weight?

It is one of the most useful things you can get right. Protein is the most filling of the three macronutrients per kilojoule, and keeping intake high while in a deficit helps preserve muscle rather than losing it along with fat. That is a bigger lever than most products in this category.
