Weight Management

A pulse eaten whole, ground into gram flour, or blended into hummus, with the large kabuli and small desi types differing in seed…

Satiety and appetite: Some trials report greater fullness and reduced later energy intake after chickpea-containing meals compared with equal-calorie control meals.

A complete package of protein, fat and micronutrients built to grow a chick, split between a protein-and-water white and a…

Satiety and appetite: Some trials report that an egg-based breakfast increases fullness and reduces energy intake at the following meal compared with a carbohydrate-based breakfast of the same calories. Effects on longer-term body weight are much less clear.

Yogurt strained to remove much of its whey, roughly doubling the protein per spoonful and leaving a thicker set. Products…

Satiety and appetite: Some trials report greater fullness and lower subsequent energy intake after high-protein yogurt snacks than after lower-protein or carbohydrate-based snacks of equal energy. The studies are short.

Flat pulses sold whole or split, and the only common legume that cooks from dry without soaking. The USDA reference entry is for…

Satiety and appetite: Some trials report greater fullness and lower subsequent energy intake after pulse-containing meals than after equal-calorie control meals, with less consistent effects on body weight over longer periods.

Whole oat groats that have been steamed and pressed flat so they hydrate quickly. The USDA reference entry is for the dry flake;…

Satiety and appetite: May support fullness within a meal: several crossover trials find oat porridge rated more satiating than equal-calorie breakfast cereals, with smaller and less consistent effects on what people eat later in the day.

Dried ground fruit of hot Capsicum annuum varieties. The USDA entry is per 100 g of the dried spice; a shake over a dish is well…

Satiety and appetite: Small crossover trials report modest reductions in appetite ratings and in energy eaten at the following meal after a capsaicin-containing meal. Effects are small, short-lived, and appear blunted in people who eat chilli habitually.

The pectoral muscle of the chicken, made up largely of fast-twitch fibres, which is why it is pale and low in fat compared with…

Satiety and appetite: Some trials report that meals built around lean poultry produce more fullness per calorie than lower-protein meals. Findings come mostly from short appetite studies rather than long-term intake data.

The most widely cultivated mushroom in the world, sold at several stages of maturity under different names. White button, cremini…

Satiety and appetite: Some trials report that replacing meat with mushrooms in a meal lowers energy intake without reducing reported fullness. The trials are small and short, and the effect follows from the lower energy density rather than anything specific to fungi.

A pome fruit grown in temperate regions worldwide, with thousands of cultivars differing in acid, sugar and polyphenol content.…

Satiety and appetite: Some trials report greater fullness and lower energy intake at the following meal when a whole apple is eaten beforehand, with the effect largely lost when the same apple is given as juice. The trials are small and short.

A large single-seeded berry with dense, oily flesh, unusual among fruits for being mostly fat rather than carbohydrate. It ripens…

Satiety and appetite: Some trials report greater fullness and lower desire to eat after meals containing avocado. Whether that carries through to lower total energy intake over a day is much less consistently shown.

Rice with the bran and germ left intact, removing only the inedible hull. The USDA reference entry is for raw grain, and rice…

Body composition: Evidence is limited for weight effects. Substitution trials report small or no differences in body weight, and observational associations are difficult to separate from the rest of the diets involved.

The kidney-shaped seed that grows beneath the cashew apple, always sold shelled and heat-treated because the shell contains…

Body composition: Evidence is limited: trials adding cashews to the diet generally report no meaningful change in body weight, which is itself a useful finding given their energy density.

A cultivated Brassica oleracea grown for its dense head of undeveloped flower buds. Its mild flavour and low carbohydrate content…

Satiety and appetite: Substituting cauliflower for a starchy staple lowers the energy density of a meal, and lower energy density is associated with reduced intake in feeding studies. Trials on cauliflower specifically are lacking.

A large cold-water groundfish with lean, flaky white flesh that stores its oil in the liver rather than the muscle. That anatomy…

Satiety and appetite: Some trials report greater fullness after fish-based meals than after equivalent meat-based meals. The number of studies is small and the differences are modest.

A fresh, unripened cheese made by acidifying milk and draining the curd without pressing, leaving the loose grains in a little…

Satiety and appetite: Some trials report greater fullness after high-protein dairy snacks than after carbohydrate-matched alternatives. The studies are short and test protein amount more than cottage cheese as a food.

Immature seeds of the pea plant, eaten fresh or frozen while still sweet and starchy rather than dried. Unlike the dried pulses…

Satiety and appetite: Evidence is limited. Small trials report increased fullness after pea-containing meals, with inconsistent effects on later energy intake.

Leaves of Camellia sinensis heated soon after picking to stop enzymatic browning, which leaves the catechins largely intact. The…

Body composition: Meta-analyses of green tea catechin trials report very small average weight differences, generally around a kilogram or less over several months, mostly using high-dose extracts often combined with caffeine. The effect is too small to be worth building a plan around, and the extract doses carry their own liver caution.

Beef trimmings ground to a uniform texture and sold by lean-to-fat ratio, most commonly between 70% and 95% lean. The ratio is…

Satiety and appetite: Some trials report greater fullness after high-protein meals containing beef than after lower-protein meals of the same energy. Most of this work is short, single-meal testing rather than evidence about long-term intake.

A hard-shelled Australian nut with the highest fat content of any common nut, dominated by monounsaturated fat including the…

Satiety and appetite: Evidence is limited to a few short trials suggesting nuts in general increase fullness; macadamia-specific appetite research is minimal.

Milk fermented with Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, which acidify it until the casein…

Body composition: Some cohort analyses link regular yogurt intake with less weight gain over time. The trial evidence is thin and confounding by overall diet pattern is a serious limitation.

The white pectoral muscle of the domestic turkey, leaner and larger-grained than chicken breast. Fresh roasting joints and…

Satiety and appetite: Some trials report higher fullness ratings after lean high-protein meals than after matched lower-protein meals. The effect is attributed to protein content generally rather than to turkey as such.

Cow milk with its fat left in, standardised to around 3.25% in most markets and almost always pasteurised. It is an emulsion in…

Body composition: Some trials report modest effects of dairy intake on body weight and fat mass within energy-controlled diets. Results are inconsistent and heavily dependent on what the dairy replaces.

The edible seed of a stone fruit closely related to the peach, eaten raw, roasted or ground into flour and butter. The USDA…

Satiety and appetite: Several trials report that almonds increase fullness and that adding them to the diet produces less weight gain than their calorie content would predict, partly because some fat is not absorbed from intact nuts.

A cereal grain sold either hulled, with the bran intact, or pearled, with the bran abraded away. The USDA reference entry is for…

Satiety and appetite: Evidence is limited for appetite effects. Small crossover trials report greater fullness and lower subsequent intake after barley meals, but the studies are few and short.

The dried unripe fruit of the Piper nigrum vine, used whole or ground. The USDA entry is per 100 g of ground pepper, whereas a…

Body composition: Piperine is sold as a metabolism-raising ingredient in fat-loss products. Human trials testing piperine on its own for body weight or fat mass are essentially absent, and the products it appears in almost always contain caffeine as well.

Cream churned until the fat globules coalesce and separate from the buttermilk, leaving a product that is overwhelmingly fat.…

Body composition: Evidence is limited for butter affecting body composition. Claims built on its conjugated linoleic acid content come from supplement trials using doses many times what butter supplies, and those trials themselves report small and inconsistent effects.

The fibrous leaf stalks of a cultivated umbellifer, eaten raw or used as an aromatic base in cooking. It is mostly water by…

Satiety and appetite: Celery is very low in energy and high in water and fibre, and foods with those properties are associated with lower energy intake in feeding studies. That is a property of the food category rather than a finding about celery itself.

Tiny seeds from a Mexican member of the mint family that form a thick gel when hydrated, because of soluble mucilage in the seed…

Body composition: Chia is widely marketed for weight loss, and the trials that tested it do not support that. Randomised trials adding chia to the diet have generally found no meaningful difference in body weight or waist circumference.

Dried inner bark from several Cinnamomum species. Almost all supermarket cinnamon is cassia, which contains far more coumarin…

Body composition: Cinnamon is heavily marketed for weight loss and appetite control. The trials that measured body weight or fat mass are few, short and largely null, so there is not enough human evidence to support that use.

Fat extracted from coconut flesh, solid below about 24 degrees Celsius and dominated by saturated fatty acids, principally lauric…

Body composition: The weight-loss claim rests on medium-chain triglyceride research using purified oils at doses well above culinary use. Trials of coconut oil at realistic amounts do not show meaningful effects on body weight or fat mass.

The dried seed of Cuminum cyminum, used whole or ground across South Asian, Middle Eastern and Latin American cooking. The USDA…

Body composition: Cumin is promoted for weight loss on the strength of a few short trials with methodological limitations and no independent replication. That is not enough to draw a conclusion from.

The rhizome of Zingiber officinale, used fresh, dried and ground, or pickled. Fresh and dried ginger are not interchangeable in…

Body composition: Ginger is widely marketed for fat loss, often as a tea or shot. The trials that measured body weight are small, brief and inconsistent, with average differences too small to be meaningful, so there is not enough dependable evidence to support that use.

A large, bitter-sweet citrus fruit, a hybrid of pomelo and sweet orange. Pink and red varieties owe their colour to lycopene,…

Body composition: The idea that grapefruit has a specific fat-burning property dates to mid-century fad diets and has no dependable human research behind it. Where trials show weight change, it tracks with eating fewer calories overall rather than with anything particular to the fruit.

A tart, deep red infusion of dried Hibiscus sabdariffa calyces, drunk hot or cold and containing no caffeine. It is one of the…

Body composition: Hibiscus is a standard ingredient in slimming and so-called cleansing teas. The trials measuring body weight are few, short and inconsistent, and any weight change from a laxative or diuretic effect is not fat loss.

The large red-skinned variety of the common bean, and the one carrying the highest concentration of the toxic lectin…

Body composition: White kidney bean extract is marketed as a starch blocker for weight loss. The trials are small, short, of poor quality and inconsistent, and none of this applies to eating cooked beans as food.

Salted napa cabbage layered with chilli, garlic, ginger and usually a seafood element, then fermented by the bacteria native to…

Body composition: Evidence is limited for kimchi affecting body weight or fat mass. A handful of small short trials exist with inconsistent results, and the popular weight-loss framing goes well beyond what they show.

A highly acidic citrus fruit used mainly for its juice and zest rather than eaten whole. Citric acid makes up a large share of…

Body composition: Lemon water is heavily promoted for weight loss and for changing body pH. Neither idea has dependable human research behind it, and blood pH is held in a narrow range by the lungs and kidneys regardless of diet.

Botanically a legume that ripens underground, not a tree nut, though its fat content and culinary use put it with the nuts. The…

Satiety and appetite: Some trials report that peanuts increase fullness and displace other snack intake, with body weight generally unchanged despite the added calories.

A hollow aggregate fruit made up of many small drupelets, harvested from thorny Rubus canes. Fragile enough that most of the crop…

Body composition: Raspberry ketone became a popular weight-loss ingredient on the strength of rodent and cell studies. There is no dependable human research showing that either the supplement or the fruit changes body weight or fat mass.

A cold-hardy cereal grain used mainly for dense breads and crispbreads in northern and eastern Europe. The USDA reference entry…

Satiety and appetite: Some trials report greater and longer-lasting fullness after wholegrain rye bread than after refined wheat bread, with less consistent effects on total daily energy intake.

The dried stigmas of the Crocus sativus flower, harvested by hand and the most expensive spice by weight. The USDA entry is per…

Body composition: Saffron extracts are widely sold for appetite control and snacking behaviour. The supporting trials are few, small and largely commercially sponsored, which is not enough to draw a conclusion from.

A starchy storage root in the morning glory family, unrelated to the potato. Flesh colour ranges from white through orange to…

Body composition: Sweet potato is frequently recommended as a weight-loss carbohydrate. There is no dependable human research showing that substituting it for other starchy foods changes body weight or fat mass.
