Diet & Sports Nutrition

Sports and diet nutrition is easy to overspend on, so look at cost per serving and grams of protein or carbs per scoop rather than the tub size. Taste and mixability matter too, since a powder you dislike ends up wasted. We rank by genuine customer ratings, and for brands like Optimum Nutrition or Science in Sport we add ratings from beyond Amazon. Meal-replacement products support a plan, not a whole diet, so speak to a GP before big changes.

Common questions

How much protein per serving should I look for?

Most whey powders give around 20 to 25 grams a scoop, which suits general training. Check the price per serving, not per tub, since scoop sizes differ. If you struggle to hit your protein from food, a shake helps, but whole foods should still do most of the work.

Do meal-replacement shakes help with weight loss?

They can, by controlling portions and calories, and brands like SlimFast build a routine around that. The weight tends to return if you go back to old habits, so treat them as a short-term tool. Anyone with a health condition should check with a GP first.

Are energy gels worth it for casual exercise?

For runs or rides under an hour, usually not, since water and normal food cover you. Gels like Science in Sport come into their own on long endurance efforts where quick carbs matter. For everyday gym sessions they are an extra cost with little real benefit.
